Safety, Tolerability, and Preliminary Efficacy of the Anti-Fibrotic Small Molecule PRI-724, a CBP/β-Catenin Inhibitor, in Patients with Hepatitis C Virus-related Cirrhosis: A Single-Center, Open-Label, Dose Escalation Phase 1 Trial

45 views | Jun 19 2019

Kimura K et al. showed that administration of 10 or 40mg/m2/day intravenous PRI-724 over 12weeks was well-tolerated by patients with HCV cirrhosis; however, liver injury as a possible related serious adverse event was observed in the 160mg/m2/day cohort. [Read the Full Post]

Histone deacetylase 6 inhibitor ACY-1215 protects against experimental acute liver failure by regulating the TLR4-MAPK/NF-κB pathway

179 views | Jun 19 2019

Zhang WB et al. showed that ACY-1215 has potential therapeutic value in mice with ALF by directly inhibiting inflammatory response via regulation of the TLR4-MAPK/NF-kB pathway. [Read the Full Post]

A DSTYK mutation activates ERK1/2 signaling to promote intraspinal dissemination in a case of solitary fibrous tumor/hemangiopericytoma

49 views | Jun 18 2019

Tang G et al. revealed the potential role of DSTYK mutation in the regulation of intraspinal metastasis of SFT/HPC, which might provide new biological insights into this rare disease. [Read the Full Post]

Simultaneous Inhibition of EGFR and HER2 via Afatinib Augments the Radiosensitivity of Nasopharyngeal Carcinoma Cells

112 views | Jun 18 2019

Huang F et al. indicated the potential of repositioning afatinib or other ERBB-family-targeted agents for improving radiation response in NPC cells. [Read the Full Post]

Irisin Is Controlled by Farnesoid X Receptor and Regulates Cholesterol Homeostasis

54 views | Jun 17 2019

Li H et al. showed taht activation of FXR induces FNDC5 mRNA expression in human and increased the circulating level of Irisin in Rhesus macaques. FNDC5/Irisin is a direct transcriptional target of FXR. Irisin may be a novel therapeutic strategy for dyslipidemia and atherosclerosis. [Read the Full Post]

RIP3 inhibition protects locomotion function through ameliorating mitochondrial antioxidative capacity after spinal cord injury

67 views | Jun 17 2019

Wang Y et al. suggested improving antioxidative capacity as a potential multifunctional treatment after SCI and the broader possibility of targeting RIP3 activity as a therapeutic window for spinal neuroprotective intervention. [Read the Full Post]

Puromycin reaction for the A site-bound peptidyl-tRNA

41 views | Jun 16 2019

Semenkov Yu et al. indicated that the transpeptidation reaction per se triggers conformational changes in the ribosomal complex bringing the 3'-end of a newly synthesized peptidyl-tRNA nearer to the peptidyl-site of the peptidyltransferase center. This is detected functionally as the ability of such an A site bound peptidyl-tRNA to react with puromycin. This reaction is highly pronounced at elevated (25 degrees C) temperature but can be hardly detected at 0 degrees C. [Read the Full Post]
