Treatment with XAV-939 prevents in vitro calcification of human valvular interstitial cells

186 views | Nov 10 2019

Dittfeld C et al. indicated that XAV-939 was therefore able to prevent calcification of human VIC cultures, and XAV-939 treatment was accompanied by upregulation of active non-phospho-β-catenin. Although XAV-939 does not downregulate active β-catenin, treatment with XAV-939 results in Sox9 upregulation that may prevent the calcification process. [Read the Full Post]

The novel inhibitor PRI-724 for Wnt/β-catenin/CBP signaling ameliorates bleomycin-induced pulmonary fibrosis in mice

489 views | Nov 10 2019

Okazaki H et al. suggested that the β-catenin/CBP inhibitor PRI-724 is a potent antifibrotic agent that acts by modulating the activity of macrophages in the lungs. [Read the Full Post]

Dual mTORC1/2 inhibition by INK-128 results in antitumor activity in preclinical models of osteosarcoma

0 views | Nov 08 2019

Jiang H et al. showed that INK-128 exerts potent anti-OS activity in vitro and in vivo. INK-128 might be further investigated as a novel anti-OS agent. [Read the Full Post]

Pan-mTOR inhibitor MLN0128 is effective against intrahepatic cholangiocarcinoma in mice

91 views | Nov 08 2019

Zhang S et al. suggested that mTOR kinase inhibitors may be beneficial for the treatment of ICC, even in tumors that are resistant to standard of care chemotherapeutics, such as gemcitabine/oxaliplatin-based regimens, especially in the subset of tumors exhibiting activated AKT/mTOR cascade. Lay summary: We established a novel mouse model of intrahepatic cholangiocarcinoma (ICC). Using this new preclinical model, we evaluated the therapeutic potential of mTOR inhibitor MLN0128 vs. gemcitabine/oxaliplatin (the standard chemotherapy for ICC treatment). Our study shows the anti-neoplastic potential of MLN0128, suggesting that it may be superior to gemcitabine/oxaliplatin-based chemotherapy for the treatment of ICC, especially in the tumors exhibiting activated AKT/mTOR cascade.

An integrative pharmacogenomics analysis identifies therapeutic targets in KRAS-mutant lung cancer

211 views | Nov 07 2019

Wang H et al. developed a genotype-based strategy that identifies CK2 as a promising co-target in KRAS(G12C) mutant NSCLC by using available pharmacogenomics gene expression datasets. This approach is applicable to other oncogene driven cancers. [Read the Full Post]
