3rd IRDiRC Conference – Trends in Patient Advocacy

As mentioned in last week’s blog, the 3rd International Rare Disease Research Consortium (IRDiRC) conference was held on the 8-9th February in Paris bringing together international experts in the rare disease field to discuss progress and to set new goals. One of the sessions of the conference focused on global trends in patient advocacy in the rare … Read more…

3rd International Rare Disease Research Consortium Conference

The 3rd International Rare Disease Research Consortium (IRDiRC) conference was held last week in Paris. It brought together international experts in the fields of public health, funding agencies, academic research, patient advocacy and health industry to discuss the progress in the rare disease field and to set new goals for the next decade. The conference … Read more…

BHD in patients undergoing chest CT and characteristics of BHD in Korea.

To date, there have been no prospective studies attempting to diagnose BHD syndrome or literature reviews on BHD in Korea. Park et al. (2017) address this in their new study that aims to detect BHD prospectively in patients undergoing chest computed tomography (CT) scans and to classify the characteristics of BHD in Korea. The authors … Read more…

TSC1 expression is affected by VHL alterations and HIF-1α production in clear-cell RCC

VHL genetic alterations do not affect the production of HIF-α in clear-cell renal cell carcinoma (ccRCC). However, their effects on tuberous sclerosis proteins (TSC1/2) and heat shock protein 90 (Hsp90) expression are currently unknown. In a recent study, Damjanovic et al. (2016) evaluated the impact of VHL genetic alterations and HIF-α production on the expression of TSC proteins … Read more…

RCC: Updates on Guidelines for Adjuvant Therapy and new drug combination

The European Association of Urology (EAU) Renal Cell Carcinoma (RCC) guidelines panel has recently updated its recommendation on adjuvant therapy with sunitinib in non-metastatic RCC after surgical tumour removal (Bex et al., 2016). These clinical guidelines provide urologists with evidence-based information and recommendations for the management of RCC and the panel includes urological surgeons, oncologists, … Read more…

Nutrient-dependent FNIP degradation regulates FLCN localization and promotes renal cancer progression

Birt-Hogg-Dubé (BHD) syndrome is a rare disorder caused by mutations in FLCN and associated with increased risk of kidney cancer. It has been shown that FLCN-interacting protein 1 and 2 (FNIP1 and FNIP2) double knockout mice, like the FLCN knockout mice, develop renal carcinoma (Hasumi et al., 2015). However, the molecular mechanisms linking FNIP and … Read more…

H255Y and K508R missense mutations in FLCN promote kidney neoplasia

The germline FLCN missense mutations H255Y (Hasumi et al., 2009) and K508R (Toro et al., 2008) have been identified in patients with bilateral multifocal (BMF) kidney tumours and other clinical symptoms of Birt-Hogg-Dube (BHD) syndrome, or with BMF kidney tumours as the only manifestation. Building on their previous work identifying the H255Y mutation in human … Read more…

Annual review 2016

2016 has been a busy year for BHD research. With the new year approaching, this week’s blog will review the studies we’ve particularly enjoyed writing about and revisit the year’s highlights. Iribe et al. (2016) assessed several RCC subtypes from BHD patients to determine if they had similar or distinct patterns of genetic abnormalities. Only a few chromophobe RCC … Read more…

Establishment of a new BHD Syndrome cell line

Birt-Hogg-Dubé syndrome is caused by mutations in the FLCN gene. The FLCN protein acts as a tumour suppressor and BHD patients have a high risk of developing renal cell carcinoma (RCC). The mechanisms of tumour formation in BHD have been investigated using mouse models and human RCC tissues. However, in vitro signalling studies of human renal cells with mutant FLCN … Read more…
