415 views | Jan 18 2019

Bang YJ et al. showed that Ipatasertib/mFOLFOX6 compared with placebo/mFOLFOX6 did not improve PFS in unselected or biomarker-selected patients. No unexpected safety concerns were observed. [Read the Full Post]

Cisplatin is retained in the cochlea indefinitely following chemotherapy

132 views | Jan 17 2019

Breglio AM et al. demonstrated long-term retention of cisplatin in the human cochlea, and they point to the stria vascularis as an important therapeutic target for preventing cisplatin ototoxicity. [Read the Full Post]

Tezacaftor-Ivacaftor in Residual-Function Heterozygotes with Cystic Fibrosis

187 views | Jan 17 2019

Rowe SM et al. showed that CFTR modulator therapy with tezacaftor-ivacaftor or ivacaftor alone was efficacious in patients with cystic fibrosis who were heterozygous for the Phe508del deletion and a CFTR residual-function mutation. [Read the Full Post]

Glucose Metabolism and AMPK Signaling Regulate Dopaminergic Cell Death Induced by Gene (α-Synuclein)-Environment (Paraquat) Interactions

152 views | Jan 16 2019

Anandhan A et al. demonstrated that glucose metabolism and AMPK regulate dopaminergic cell death induced by gene (α-synuclein)-environment (PQ) interactions. [Read the Full Post]

Dipeptidyl Peptidase-4 Induces Aortic Valve Calcification by Inhibiting Insulin-Like Growth Factor-1 Signaling in Valvular Interstitial Cells

164 views | Jan 16 2019

Choi B et al. suggested that DPP-4 could serve as a potential therapeutic target to inhibit calcific aortic valve disease progression. [Read the Full Post]

Efficacy of a bleomycin microneedle patch for the treatment of warts

153 views | Jan 15 2019

Ryu HR et al. indicated the bleomycin microneedle patch can be an effective, convenient, and innovative treatment modality for warts. [Read the Full Post]

A randomized, open-label study of the efficacy and safety of AZD4547 monotherapy versus paclitaxel for the treatment of advanced gastric adenocarcinoma with FGFR2 polysomy or gene amplification

333 views | Jan 15 2019

Van Cutsem E et at. indicated that AZD4547 did not significantly improve PFS versus paclitaxel in gastric cancer FGFR2 amplification/polysomy patients. Considerable intratumor heterogeneity for FGFR2 gene amplification and poor concordance between FGFR2 amplification/polysomy and FGFR2 expression indicates the need for alternative predictive biomarker testing. AZD4547 was generally well tolerated. [Read the Full Post]

MicroRNA-24-1 suppresses mouse hepatoma cell invasion and metastasis via directly targeting O-GlcNAc transferase

252 views | Jan 14 2019

Liu Y et al. suggested that as a tumor suppressor, miR-24-1 may regulate mouse hepatocarcinoma cells migration and invasion, at least partially through targeting OGT, which could regulate the O-GlcNAcylation and the stability of this oncoprotein c-Myc. This may give insight into a novel mechanism and therapy of tumor lymphatic metastasis. [Read the Full Post]
