Ex vivo AKT-inhibition facilitates generation of polyfunctional stem cell memory-like CD8+ T cells for adoptive immunotherapy

0 views | Jan 21 2019

Mousset CM et al. demonstrated that AKT-inhibitors with different modality of action promote the ex vivo generation of stem cell memory-like CD8+ T cells with a unique metabolic profile and retained polyfunctionality. Akt-inhibitor VIII and GDC-0068 outperformed other inhibitors, and are therefore promising candidates for ex vivo generation of superior tumor-reactive T cells for adoptive immunotherapy in cancer patients.

Cytokine correlation analysis based on drug perturbation

0 views | Jan 19 2019

Wallner FK et al. showed that cytokines are highly co-regulated, which provide valuable information for how a therapeutic drug might affect clusters of cytokines. In addition, a cytokine that is used as a therapeutic biomarker could be combined with its related cytokines into a biomarker panel to improve diagnostic accuracy. [Read the Full Post]

Down-Regulation of AQP4 Expression via p38 MAPK Signaling in Temozolomide-Induced Glioma Cells Growth Inhibition and Invasion Impairment

770 views | Jan 19 2019

Chen Y et al. identified that TMZ might have therapeutic potential for controlling proliferation, invasion of malignant glioma by inhibiting AQP4 expression through activation of p38 signal transduction pathway. [Read the Full Post]

Effect of VX-770 in persons with cystic fibrosis and the G551D-CFTR mutation

539 views | Jan 18 2019

Accurso FJ et al. evaluated the safety and adverse-event profile of VX-770 showed that VX-770 was associated with within-subject improvements in CFTR and lung function. These findings provide support for further studies of pharmacologic potentiation of CFTR as a means to treat cystic fibrosis. [Read the Full Post]

A phase II, randomised study of mFOLFOX6 with or without the Akt inhibitor ipatasertib in patients with locally advanced or metastatic gastric or gastroesophageal junction cancer

879 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

562 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

587 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]

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

967 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

753 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]
