Irisin Is Controlled by Farnesoid X Receptor and Regulates Cholesterol Homeostasis

89 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

113 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

82 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]

MMP14-Containing Exosomes Cleave VEGFR1 and Promote VEGFA-Induced Migration and Proliferation of Vascular Endothelial Cells

73 views | Jun 16 2019

Han KY et al. showed that MMP14-containing exosomes may be involved in the regulation of corneal neovascularization through degradation of VEGFR1 and VEGFA-induced endothelial cell proliferation and migration. [Read the Full Post]

Increased MCL-1 expression predicts poor prognosis and disease recurrence in acute myeloid leukemia

88 views | Jun 13 2019

Lonafarnib synergizes with azoles against Aspergillus spp. and Exophiala spp

84 views | Jun 13 2019

Qiao J et al. demonstrated that lonafarnib could enhance the in vitro antifungal activity of itraconazole, posaconazole and voriconazole against Aspergillus spp. and E. dermatitidis, suggesting that azoles, especially itraconazole and posaconazole, combined with farnesyltransferase inhibitor might provide a potential strategy to the management of Aspergillus and Exophiala infections. However, further studies are warranted to elucidate the underlying mechanism and to investigate the potential of reliable and safe application in clinical practice. [Read the Full Post]

Vaassen P et al. suggested that MEK inhibitors are likely to play a significant role in providing a cure for one of the most devastating manifestations of NF1. [Read the Full Post]

Combination of Emricasan with Ponatinib Synergistically Reduces Ischemia/Reperfusion Injury in Rat Brain Through Simultaneous Prevention of Apoptosis and Necroptosis

127 views | Jun 10 2019

Tian J et al. concluded that combination of emricasan with ponatinib could synergistically reduce I/R injury in rat brain through simultaneous prevention of apoptosis and necroptosis. Our findings might lay a basis on extension of the clinical indications for emricasan and ponatinib in treating ischemic stroke. [Read the Full Post]

Effect of CHK1 Inhibition on CPX-351 Cytotoxicity in vitro and ex vivo

69 views | Jun 10 2019

Vincelette ND et al. showed that CHK1 inhibition increases the antiproliferative effect of CPX-351 on primary AML specimens ex vivo, offering the possibility that CPX-351 may be well suited to combine with CHK1-targeted agents. [Read the Full Post]

Safety evaluation of combination carboplatin and toceranib phosphate (Palladia) in tumour-bearing dogs: A phase I dose finding study

112 views | Jun 09 2019

Wouda RM et al. indicated the dose-limiting toxicity was neutropenia. Two dogs experienced a partial response, and 6 maintained stable disease. Combination carboplatin and toceranib chemotherapy was well-tolerated. Clinical benefit was observed in most cases. This protocol warrants further investigation in phase II/III trials.
