Why are patient registries important?

by Lizzie Perdeaux in BHD Research Blog

How many people have BHD? Who will develop which symptoms, when?  How severe will they be? These are very straightforward questions, but there is not sufficient information to accurately answer them at the moment. This is where patient registries are … Continue reading →... Read more »

FLCN may act as a molecular switch

by Lizzie Perdeaux in BHD Research Blog

Chromosome translocations involving the transcription factor TFE3, leading to its overexpression, cause roughly 15% of renal cell carcinomas in patients under 45 years of age (Kuroda et al., 2012). TFE3 is constitutively activated in FLCN-null cells (Hong et al., 2010), … Continue reading →... Read more »

Rare diseases are fundamental to understanding common diseases

by Lizzie Perdeaux in BHD Research Blog

Research has historically concentrated on more common diseases, seeking to benefit the many rather than the few, and as a result rare diseases have often been overlooked. However, a growing body of evidence shows that rare disease research can yield … Continue reading →... Read more »

Pheochromocytomas and paragangliomas may be a rare symptom of HLRCC

by Lizzie Perdeaux in BHD Research Blog

HLRCC is a kidney cancer predisposition syndrome characterised by skin lesions, uterine fibroids and papillary renal cancers, and caused by heterozygous inactivating mutations in the FH gene. HLRCC is a very rare disease which affects roughly 300 families worldwide. As … Continue reading →... Read more »

FLCN’s roles in RhoA and mTOR signalling may be part of a single, larger signalling pathway

by Lizzie Perdeaux in BHD Research Blog

FLCN has been previously reported to regulate both mTOR and RhoA signalling. Although currently considered to be two unrelated functions of FLCN, a recently published study suggest that the two pathways may form one larger signalling pathway. Following the finding … Continue reading →... Read more »

How the Saatchi Bill will help rare disease patients

by Lizzie Perdeaux in BHD Research Blog

FLCN deficient tumours may be sensitive to radiotherapy

by Lizzie Perdeaux in BHD Research Blog

Autophagy is the process through which cells recycle proteins and organelles for energy, and is often dysregulated in kidney cancers. A recent study shows that autophagy is increased in FLCN-null renal carcinoma cells, and that these cells are more sensitive … Continue reading →... Read more »

FLCN may control cell-cell adhesion via PKP4 and Rab11a

by Lizzie Perdeaux in BHD Research Blog

In 2012, two separate studies reported that FLCN interacts with Plakophilin4 (PKP4) to regulate RhoA signalling and cell-cell adhesion. PKP4, together with Ect2, interacts with RhoA to regulate Rho signalling, contractile ring formation and contraction, and actin reorganisation during cell … Continue reading →... Read more »

Compound heterozygous and mosaic mutations in kidney cancer predisposition syndromes

by Lizzie Perdeaux in BHD Research Blog
