Multikinase Inhibitor CT-707 Targets Liver Cancer by Interrupting the Hypoxia-Activated IGF-1R-YAP Axis.

Given that Yes-associated protein (YAP) signaling acts as a critical survival input for hypoxic cancer cells in hepatocellular carcinoma (HCC), disruption of YAP function and the maintenance of hypoxia is an attractive way to treat HCC. Utilizing a cell-based YAP-TEAD luciferase reporter assay and functional analyses, we identified CT-707, a China-FDA approved multi-kinase inhibitor under clinical trial with remarkable inhibitory activity against YAP function. CT-707 exhibited prominent cytotoxicity under hypoxia on HCC cells, which was attributable to the inhibition of YAP signaling.

Luteolin Suppresses Teratoma Cell Growth and Induces Cell Apoptosis via Inhibiting Bcl-2.

Luteolin, which is found in plant foods, has a range of therapeutic applications. In order to examine the potential roles of luteolin in ovarian teratocarcinoma, the human ovarian teratocarcinoma cell line PA-1 was selected for functional experiments in vitro and in vivo. We demonstrated that luteolin inhibited the proliferation and colony formation of PA-1 cells in vitro.

[Analysis of 574 cases of high-fall death].

Objective: To establish a database of high-fall death cases for future forensic study and practice, based on the scene investigation, injury characteristics and other informations.

Methods: Five hundred and four cases of high-fall death from 5 provinces and cities were included in the study. Data including personal information of the deceased, scene investigation, autopsy findings, history of mental illness and the results of toxicology were collected and analyzed.

[Application of nested PCR and sequencing technique to detect point mutations of the 23S rRNA gene of Mycoplasma pneumoniae].

Objective: To establish a quick method to detect drug resistance of Mycoplasma pneumoniae (MP) and study the condition of drug resistance in MP infection.

Methods: MP 23S rRNA target gene in throat swab specimens from 200 patients with suspected MP infection was detected by using nested PCR and DNA sequencing. The result of 23S rRNA gene detection was confirmed by MP isolation and drug susceptibility test in vitro for reliability.
