Improved fluorescence assays to measure the defects associated with F508del-CFTR allow identification of new active compounds
0 views | Oct 15 2017
Langron E et al. showed that most known potentiators have a negative influence on F508del-CFTR biogenesis/stability, which means membrane exposure needs to be monitored early during the development of drugs targeting CFTR. The combined use of the two fluorescence assays described here provides a useful tool for the identification of improved potentiators and correctors. The assays could also prove useful for basic scientific investigations on F508del-CFTR, and other CF-causing mutations. [Read the Full Post]

Effects of bavachin and its regulation of melanin synthesis in A375 cells
0 views | Oct 10 2017
Wang JH, et al. found that bavachin inhibited the synthesis of melanin on A375 cells by inhibiting the protein and mRNA expression of TYR, TRP-1, TRP-2, ERK1, ERK2 andJNK2. [Read the Full Post]
Regulation of the Nampt-mediated NAD salvage pathway and its therapeutic implications in pancreatic cancer
654 views | Oct 10 2017
Ju HQ et al. suggested that Nampt inhibition may override gemcitabine resistance by decreasing the NAD level and suppressing glycolytic activity, warranting further clinical investigation for pancreatic cancer treatment. [Read the Full Post]

2855 views | Oct 09 2017
Grygielewicz P et al. provide experimental evidence that EMT-mediated resistance might emerge in gastric cancer patients following treatment with FGFR inhibitors, and mubritinib or AUY922 treatment may be an alternative therapeutic strategy for these patients. [Read the Full Post]
Diverse, Biologically Relevant, and Targetable Gene Rearrangements in Triple-Negative Breast Cancer and Other Malignancies
1145 views | Oct 08 2017
Shaver TM et al. identified a diverse array of novel and known hybrid transcripts, including rearrangements between noncoding regions and clinically relevant genes such as ALK, CSF1R, and CD274/PD-L1 The over 1,000 genetic alterations we identified highlight the importance of considering noncoding gene rearrangement partners, and the targetable gene fusions identified in TNBC demonstrate the need to advance gene fusion detection for molecularly heterogeneous cancers.
