The Genetic Roots of Schizophrenia

by Gabriel in Lunatic Laboratories

I have a friend who lost an eye — not in a war zone like you might suspect given my background — but to his brother. Yes, you read that correctly, his brother tried to kill him and in the process he lost his eye. I’ve told this story before, but whenever new schizophrenia research comes out I feel the need to tell it again. While he has forgiven his brother (partly because not long after, he was diagnosed as schizophrenic), he will not be able to see him again until he is released from prison. A tragedy that could’ve been avoided had he been diagnosed sooner.... Read more »

Sweating Is The Pits

by Mark E. Lasbury in The 'Scope

New research is delving into the possible negative aspects of antiperspirants and deodorants. A 2014 study indicates that bacterial fauna is altered by the use of antiperspirants and can lead to overgrowth of bacteria that actually produce more foul smelling chemicals. On a more important note, research is showing that aluminum from antiperspirants may contribute to breast cancer growth, including promotion of estrogen hormone production, altered iron metabolism, and increased oxygen radical formation. However, no definitive proof shows that antiperspirants cause breast cancer, and a 2013 study showed no difference in aluminum levels from normal to diseased tissue.... Read more »

Zinc and copper and autism

by Paul Whiteley in Questioning Answers

The paper by Li and colleagues [1] looking at serum copper (Cu) and zinc (Zn) levels in a group of participants diagnosed with an autism spectrum disorder (ASD) is the source material for today's post. Highlighting how "mean serum Zn levels and Zn/Cu ratio were significantly lower in children with ASD compared with normal cases... whereas serum Cu levels were significantly higher" the continued focus on the metallome in autism carries on at a pace. I should at this point out that I'm not in favour of the use of the word 'normal' in this or any context (anyone who feels that they are normal, please make themselves known to the population at large)."Bring me... the bore worms!"Anyhow... I've talked zinc and autism / other conditions on this blog quite a few times (see here and see here). Alongside other more recent data [2] there is a growing realisation that zinc deficiency present in at least some diagnosed on the autism spectrum might have quite a few implications. With this thought in mind, I might also draw your attention to the recent paper by Chaves-Kirsten and colleagues [3] talking about how zinc might also show some connection to the protein kinase of the hour, mTOR (see here) and in particular reducing mTOR levels in a rodent model of autism. This follows other work in this area [4].The Li paper alongside looking at individual levels of zinc and copper and how they seemed to correlate with presented symptoms according to the Childhood Autism Rating Scale (CARS) also talks about the zinc/copper ratio which is something that has been previously discussed in the peer-reviewed literature with reference to autism and various other conditions as per the excellent review by Osredkar & Sustar [5] (open-access). The paper by Faber and colleagues [6] for example, indicated that a low Zn/Cu ratio may "indicate decrement in metallothionein system functioning". They also talked about how issues with this ratio "may be a biomarker of heavy metal, particularly mercury, toxicity in children with ASDs" as per the various biological uses of metallothionein [7]. I know this moves discussions into some quite uncomfortable realms but science is science (see here) and one should not be afraid to have scientific discourse on any topic. Importantly too, the Faber results also seemed to show more than a passing similarity to those presented by Li et al. Same goes for the paper by Russo and colleagues [8].The other interesting point recorded by Li and colleagues was their use of the good 'ole ROC curve as a means to indicate an "auxiliary diagnosis of autism". More frequently linked to a certain Egyptian-Saudi autism research group (see here), ROC curves - "a fundamental tool for diagnostic test evaluation" - basically plots the true positive rate against the false positive rate for a test. Li et al projected the cut-off value for the Zn/Cu ratio to be 0.665 for a diagnosis, with "a sensitivity of 90.0% and a specificity of 91.7%". Bearing in mind the relatively small participants included for analysis (n=60), those aren't bad figures for sensitivity and specificity remembering my recent discussions on the observation-based classifier (OBC) from Wall and colleagues [9] (see here) and what they got.There's little more for me to say about the Li data that I haven't already said here and in other posts on this topic. If you want to read a little more about the possible role of zinc and copper in cases of autism, the report by Bjorklund [10] covers quite a bit of the literature on possible links. The next question is what might we be able to do about any issues in this area? [11]So then, The Last of the Famous International Playboys? (not me of course..)----------[1] Li SO. et al.

Need a Kidney? Lab Grown Kidneys Coming Soon!

by Gabriel in Lunatic Laboratories

Stem cells offered the promise of having a patents own organ grown to replace a failing or damaged one. Unfortunately the road to that future has been paved with seemingly insurmountable challenges. Thankfully now we are one step closer, researchers have addressed a major challenge in the quest to build replacement kidneys in the lab. Working with human-sized pig kidneys, the scientists developed the most successful method to date to keep blood vessels in the new organs open and flowing with blood.... Read more »

Inflammation of the Brain and Memory Problems

by Gabriel in Lunatic Laboratories

Neurological disorders typically involve memory issues. Most of the problems are attributed to plaques that build up in the brain (which are typically prions), yet some causes are unknown. New research however sheds some light on at least one cause of memory problems. As it turns out brain inflammation can rapidly disrupt our ability to retrieve complex memories of similar but distinct experiences.... Read more »

Insulin, growth hormone and risk of schizophrenia?

by Paul Whiteley in Questioning Answers

"Overall, the present findings suggest that metabolic and hormonal disturbances such as effects on insulin and growth hormone may represent a vulnerability factor to develop mental disorders". That was the conclusion reported by van Beveren and colleagues [1] (open-access) looking at "disruption of insulin and growth factor signaling pathways as an increased risk factor for schizophrenia"."Years ago you served my father in the Clone Wars"Drawing on data derived from participants taking part in the Genetic Risk and Outcome of Psychoses (GROUP) study [2] researchers looked at blood serum samples "to measure the levels of 184 molecules in serum from 112 schizophrenia patients, 133 siblings and 87 unrelated controls". Multiplex immunoassay was the analytical weapon of choice.The results indicated that "10 proteins were present at significantly different levels between schizophrenia patients and controls" which can be seen here. The insulin synthesis pathway showed more than a passing connection to group differences as per the appearance of insulin and precursor molecules such as proinsulin and C-peptide (connecting peptide). Some of these pathway molecules were also reported to be altered in the sibling group(s) too. Growth hormone also featured as a potentially distinguishing marker, as did adiponectin among others.The authors conclude (again) their findings for "the presence of a molecular endophenotype involving disruption of insulin and growth factor signaling pathways as an increased risk factor for schizophrenia". Perhaps even more interesting is their view of the body of work [3] suggesting that "antipsychotic drugs are known to increase peripheral glucose levels" and how, in light of their findings, "these effects may be intrinsically related to the therapeutic mechanism of action by increasing the peripheral blood glucose levels and thereby increasing glucose availability in the brain".As the authors point out, there is still quite a bit more to do in this area including examining larger samples sizes and importantly, looking at blood glucose levels as a measure of insulin resistance to further complement their findings. I note however that issues with insulin function being potentially related to mood and other psychiatric conditions are nothing new as per the various literature in this area. Anderson and colleagues [4] for example, talked about a diagnosis of diabetes doubling the odds of comorbid depression. Bearing in mind, the possible interfering effect of medication, Verma and colleagues [5] found that in drug-naive (unmedicated) patients with first-episode psychosis there was a significantly increased likelihood of diabetes to be present compared with age and sex-matched asymptomatic control participants. I don't doubt however, that any relationship is going to be complicated.Finally, and bearing in mind the prime directive of this blog (no medical or clinical advice given or intended), there is the question of how this research might translate into therapeutic intervention. A final quote from the authors on this and the possibility of: "novel disease prevention approaches, which could involve nutrition modification, stress reduction and pharmaco-therapeutic interventions, including the application of well-tolerated drugs that combat insulin resistance". Alongside the dietary aspect (which is something very favourable to this blog for lots of reasons), I am wondering whether we could also learn something from times gone by [6]? Perhaps even the appliance of prophylactic psychiatry [7]?Music to close and Andrea Bocelli sings Funiculì, Funiculà...----------[1] van Beveren NJM. et al.

The Origami Brain and a new marker for Schizophrenia

by Gabriel in Lunatic Laboratories

Anyone who has seen pictures or models of the human brain (like the one above) is aware that the outside layer, or cortex, of the brain is folded in an intricate pattern of “hills”, called gyri, and “valleys”, called sulci which give the brain it’s distinctive look. It turns out that the patterns of cortical folding are largely consistent across healthy humans, broadly speaking. However, disturbances in cortical folding patterns suggest deeper disturbances in brain structure and function.... Read more »

Treating autism in the first year of life

by Paul Whiteley in Questioning Answers

I had been waiting y'know. Waiting a while for the paper by Sally Rogers and colleagues [1] to finally appear quite a few days after the media headlines about 'reducing', 'reversing' and even 'eliminating' the signs and symptoms of autism in early infancy had appeared. Personally, I prefer the New Scientist headline: 'Early autism intervention speeds infant development' given the text of the paper. I should perhaps also add the words 'for some' to that sentence as you will hopefully see...I'm sure most people have already read about the study ins and outs: take an intervention called 'Infant Start' (IS), a relation of the Early Start Denver Model (ESDM), and apply it with a small (very small) group of "symptomatic" young infants (n=7, aged between 6-15 months old) showing signs and symptoms of autism. Plot baseline measures and progress of those children under IS using various psychometric tools including something like the Autism Observation Scale for Infants (AOSI) and old reliable: the ADOS (the Autism Diagnostic Observation Schedule) compared against four comparison groups. One of those control groups included those with similar early autism symptoms as judged by "elevated AOSI scores and clinician concerns" but who did not receive IS; a so-called "declined referral (DR) group" (n=4). Record results and report outcome based on said 12-week program and added extra sessions a few months down the line.The headline conclusion: "At 36 months, the treated group had much lower rates of both ASD [autism spectrum disorder] and DQs [developmental quotients] under 70 than a similarly symptomatic group who did not enroll in the treatment study". Further: "the pilot study outcomes are promising". I should add that when it came to the "final visit" and "based on standardized assessments and clinical judgement" 2 of the 7 children in the IS group did eventually receive a diagnosis of ASD/PDD-NOS (pervasive developmental disorder not otherwise specified). This compared with 3 of the 4 children in the DR group who met criteria for ASD/PDD-NOS (the other child "presented with intellectual disability"). Insofar as DQ - specifically "overall DQ at or below 70 at 36 months" - well, one child in the IS group fell into this category compared with 3 children in the DR group (note to authors, you've called this the 'DE' group... sorry to be pedantic). You can um-and-ah about the links between ASD and PDD-NOS for example, but suffice to say that any effect from IS was not universal across all participants included in the trial. If you'd like a few more details about the trial and results, I'll refer you to the press release from UC Davis (see here).Of course this is not the first time that this type of very early intervention has been discussed in the peer-reviewed domain. Take for example another paper by Rogers and colleagues [2] (open-access) talking about the use of ESDM with a cohort of 14-24 month old toddlers "at risk for autism spectrum disorders". The results on that occasions were slightly less dramatic than the more recent ones with the caveat that "both younger child age at the start of intervention and a greater number of intervention hours were positively related to the degree of improvement in children's behavior for most variables". I talked about this in a previous post (see here). Indeed it appears that age at start of intervention might be an important variable after all.So, where next with this research? Well, aside from some discussions reiterating how useful it would be to have something to aid early diagnosis (see here) bearing in mind that it has not been conclusively proven that all autism is present from birth (see here), discussions have turned to why such early intervention might have had the effect that it had. Brain plasticity has been mentioned, and how critical periods in early development might be particularly amenable to such intensive intervention. Of course, without the all-important "testing the treatment’s efficacy" under more controlled conditions and with larger groups, one cannot discount some role for chance in the recent findings. Not buying that as an answer? How about differing developmental trajectories then?----------[1] Rogers SJ. et al.

Omega-3 fatty acids rescues Fragile X phenotypes in Fmr1-Ko mice

by Paul Whiteley in Questioning Answers

"These results demonstrate that n-3 PUFAs dietary supplementation, although not a panacea, has a considerable therapeutic value for FXS [Fragile X syndrome] and potentially for ASD [autism spectrum disorder], suggesting a major mediating role of neuroinflammatory mechanisms".A view @ Wikipedia That was the conclusion reached by Susanna Pietropaolo and colleagues [1] who "evaluated the impact of n-3 PUFA dietary supplementation in a mouse model of fragile X syndrome (FXS), i.e., a major developmental disease and the most frequent monogenic cause of ASD". Looking at the Fmr1-KO mouse model of FXS, a mouse specifically bred to mimic the silencing of the FMR1 gene noted in FXS (see here) with onwards adverse effects for the production of FMRP, researchers looked at what happened when diets were "enriched or not with n-3 PUFAs from weaning until adulthood when they were tested for multiple FXS-like behaviors". The results seemed to indicate that "n-3 PUFA supplementation rescued most of the behavioral abnormalities displayed by Fmr1-KO mice, including alterations in emotionality, social interaction and non-spatial memory, although not their deficits in social recognition and spatial memory". Neuroinflammatory imbalances noted in the knock-out mice were also positively affected by omega-3 supplementation.I don't need to remind you that the Pietropaolo study was a study of mice and one needs to be quite careful about extrapolating animal results when it comes to humans. That being said, given the quite extensive work that has been done on FXS and the detailing of it's molecular background, one might assume that the current results are treated with a little less scepticism than in relation to other more idiopathic 'types' of autism. Still, proper trials with people are indicated as per other research.Omega-3 fatty acids have been discussed before on this blog with autism in mind (see here). The collected literature on their usefulness as supplements for autism is rather mixed at present [2] despite some emerging evidence on their involvement in various biological processes in cases of autism (see here). That being said, I'm not getting too down on omega-3 fatty acids in light of some associations being made with specific skills over and above any condition-specific relationship and some new light being shed on their use in other conditions [3]. I'm yet to find anything like an experimental trial of fatty acids in real people with FXS but did chance(!) upon the study by Lachance and colleagues [4] (open-access) talking about the use of fenretinide (N-(4-hydroxyphenyl) retinamide (4HPR)) in the test-tube and effects "associated with the normalization of arachidonic acid/docosahexaenoic acid ratio in macrophages". The effect talked about translates as a down-regulation in the "production of arachidonic acid (AA), a pro-inflammatory omega-6 polyunsaturated fatty acid, and to increase levels of omega-3 polyunsaturated docosahexaenoic acid (DHA), which has an anti-inflammatory effect". Mmm... possibly some new targets to replace quite a few disappointments when it comes to FXS therapeutics (see here).Music to close. Fontella Bass and Rescue Me.----------[1] Pietropaolo S. et al.
