PTEN activation through K163 acetylation by inhibiting HDAC6 contributes to tumour inhibition

0 views | Mar 23 2017

Meng Z et al indicated that PTEN activation by inhibiting HDAC6 significantly contributed to tumour inhibition. Therefore, non-selective HDAC or HDAC6-specific inhibitors may be more clinically suitable to treat tumours without PTEN mutations or deletions. [Read the Full Post]

Overexpression of GAB2 in ovarian cancer cells promotes tumor growth and angiogenesis by upregulating chemokine expression

1321 views | Mar 22 2017

Duckworth C et al suggestec that overexpression of GAB2 in ovarian cancer cells promotes tumor growth and angiogenesis by upregulating expression of CXCL1, CXCL2 and CXCL8 that is IKKβ-dependent. Co-targeting IKKβ and PI3K pathways downstream of GAB2 might be a promising therapeutic strategy for ovarian cancer that overexpresses GAB2. [Read the Full Post]

Tivantinib induces G2/M arrest and apoptosis by disrupting tubulin polymerization in hepatocellular carcinoma

0 views | Mar 21 2017

Xiang Q et al suggested that the potent anti-tumor activity of tivantinib in HCC was achieved by targeting microtubule. Tivantinib treatment for patients with HCC should not be selected based on MET status. [Read the Full Post]

CD4+ T cell–dependent and –independent cytokine-chemokine network changes in the immune responses of HIV-infected individuals

2185 views | Mar 20 2017

Arnold KB et al identified a critical deficiency in NK cell responses of HIV-infected individuals, independent of CD4(+) T cell depletion, which directs secreted profiles. Our findings illustrate a broad approach for identifying key disease-associated nodes in a multicellular, multivariate signaling network. [Read the Full Post]

294 views | Mar 19 2017

Olesen SH et al. suggested key roles for members of the mammalian Sterile20-like (MST) family of kinases in many aspects of biology. [Read the Full Post]

Synthetic Lethal Screens Identify Vulnerabilities in GPCR Signaling and Cytoskeletal Organization in E-Cadherin-Deficient Cells

291 views | Mar 19 2017

Telford BJ, et al. demonstrated that E-cadherin loss creates druggable vulnerabilities that have the potential to improve the management of both sporadic and familial LBC and DGC. [Read the Full Post]

Tuttle TR et al found that Tadalafil substantially reduced the growth of CAL27-derived tumors in athymic mice. Several drugs which either activate sGC or inhibit PDE5 are approved for treatment of nonmalignant conditions. These drugs could be repurposed as novel and effective therapeutics in patients with head and neck cancer. [Read the Full Post]

Development and Application of a High-Throughput Screening Method to Evaluate Antifungal Activity against Trichophyton tonsurans.

227 views | Mar 18 2017

Several novel compound classes were identified to have activity against T. tonsurans with potency comparable to known antifungals. A robust, reproducible assay is described that permits high-throughput screening in T. tonsurans. [Read the Full Post]

Establishment of Reporter Lines for Detecting Fragile X Mental Retardation (FMR1) Gene Reactivation in Human Neural Cells.

271 views | Mar 18 2017

Li M et al. provided valuable information for the generation of knockin human iPSC reporter lines for disease modeling, drug screening, and mechanistic studies. [Read the Full Post]

Structural and functional screening in human induced-pluripotent stem cell-derived cardiomyocytes accurately identifies cardiotoxicity of multiple drug types

0 views | Mar 17 2017

Doherty KR et al. showed that a multi-parameter approach examining both cardiac cell health and function in hiPS-CM provides a comprehensive and robust assessment that can aid in the determination of potential cardiac liability. [Read the Full Post]

AT-101 inhibits hedgehog pathway activity and cancer growth

817 views | Mar 17 2017

Wang J et al. demonstrated that AT-101 significantly and selectively inhibits Hh pathway activity by potentially targeting Smo and consequently suppresses the growth of Hh-driven cancer. [Read the Full Post]
