Cell Cycle Arrest and Apoptosis Are Not Dependent on p53 Prior to p53-dependent Embryonic Stem Cell Differentiation

235 views | Jun 02 2020

Sushil K Jaiswal et al. found that the multiple roles of p53 in cell cycle regulation and apoptosis were first acquired during pluripotent stem cell differentiation. [Read the Full Post]

The Role of AMPK Activation for Cardioprotection in Doxorubicin-Induced Cardiotoxicity

120 views | Feb 08 2020

Timm KN et al. introduced different agents known to activate AMPK (metformin, statins, resveratrol, thiazolidinediones, AICAR, specific AMPK activators) as well as exercise and dietary restriction, and discussed the existing evidence for their potential role in cardioprotection from doxorubicin cardiotoxicity.

Irinotecan monotherapy as third-line or later treatment in advanced gastric cancer

189 views | Aug 09 2019

Makiyama A et al. showed that Irinotecan monotherapy was relatively safely performed as salvage-line treatment for AGC in Japanese clinical practice. Careful patient selection and intensive modification of the dose of irinotecan might possibly be associated with favorable survival. [Read the Full Post]

The 5-hydrazino-3-methylisothiazole-4-carboxylic acid, its new 5-substituted derivatives and their antiproliferative activity

198 views | Jul 29 2019

Jęśkowiak I et al. showed in the conducted studies, their activity against breast adenocarcinoma MCF-7 and normal non-tumorigenic epithelial cell line derived from mammary gland MCF-10A was substantially lower. The result of this work is claimed Polish patent application. [Read the Full Post]

Non-Photoinduced Biological Properties of Verteporfin

318 views | Jun 23 2019

Gibault F et al. showed that VP is a multi-target drug interacting with several proteins implicated in major cellular processes. Although this does not impact its clinical use, VP does not seem to be the ideal drug for pharmacological inhibitions of YAP/TEAD. [Read the Full Post]

Slow release of etoposide from dextran conjugation shifts etoposide activity from cytotoxicity to differentiation: A promising tool for dosage control in anticancer metronomic therapy

241 views | Apr 01 2019

De Nicola M et al. indicated slow release as a promising novel strategy for stabilizing low drug levels in metronomic regimens. [Read the Full Post]

Release of Moxifloxacin from Contact Lenses Using an In Vitro Eye Model: Impact of Artificial Tear Fluid Composition and Mechanical Rubbing

349 views | Nov 29 2018

Phan CM et al. suggested that sophisticated in vitro models are necessary to adequately model on-eye drug release from CL materials. [Read the Full Post]

Double-loop hairpin probe and doxorubicin-loaded gold nanoparticles for the ultrasensitive electrochemical sensing of microRNA

293 views | Oct 26 2018

Tao Y et al. found that the miRNA was capable of being detected in a limit of 0.17pM and other kinds of miRNA were discriminated facilely by this method. [Read the Full Post]

DW09849, a selective phosphatidylinositol 3-kinase (PI3K) inhibitor, prevents PI3K signaling and preferentially inhibits proliferation of cells containing the oncogenic mutation p110α (H1047R).

423 views | Sep 22 2018

Liu JL et al. suggested that DW series compounds, especially DW09849, selectively targeting PI3Kα with less off-target effects than PIK-75, provide new clues for the design and discovery of new specific PI3Kα inhibitors for cancer therapy. [Read the Full Post]
