Tyrosyl-DNA phosphodiesterase and the repair of 3'-phosphoglycolate-terminated DNA double-strand breaks

0 views | Sep 03 2020

Tong Zhou et al. suggested a role for TDP1 in repair of 3'-PG double-strand breaks in vivo. [Read the Full Post]

Inhibition of DNA-PKcs activity re-sensitizes uveal melanoma cells to radio- and chemotherapy

11 views | Sep 03 2020

Bingjie Zhang et al. demonstrated increased DNA double strand break repair as a mechanism of resistance to ionizing radiation and Selumetinib, and identified DNA-PKcs as a promising target for radio-and chemotherapy in UM patients. [Read the Full Post]

A phase 2 trial of buparlisib in patients with platinum-resistant metastatic urothelial carcinoma

16 views | Aug 17 2020

Victor McPherson et al. proposed that given the modest clinical activity and substantial toxicity of buparlisib, future trials of PI3K inhibitors in patients with UC should focus on isoform-selective PI3K inhibitors in genomically selected patients. [Read the Full Post]

The role of CUDC-907, a dual phosphoinositide-3 kinase and histone deacetylase inhibitor, in inhibiting proliferation of adult T-cell leukemia

17 views | Aug 17 2020

Chie Ishikawa et al. showed that CUDC-907 might be a potential therapeutic agent for ATL. [Read the Full Post]

Macrophages confer resistance to PI3K inhibitor GDC-0941 in breast cancer through the activation of NF-κB signaling

62 views | Aug 13 2020

Muhammad Waqas Usman et al. suggested macrophages in microenvironment may contribute to the resistance of breast cancer cells to PI3K inhibition and reveal a new combination paradigm to improve the efficacy of PI3K-targeted therapy. [Read the Full Post]

A PI3K- and GTPase-independent Rac1-mTOR mechanism mediates MET-driven anchorage-independent cell growth but not migration

28 views | Aug 12 2020

Alexia Hervieu et al. revealed a GTPase-independent role for Rac1 in mediating a PI3K-independent MET-to-mTOR pathway and suggested alternative or combined strategies that might overcome resistance to RTK inhibitors in patients with cancer. [Read the Full Post]

Inhibition of PI3K by Copanlisib Exerts Potent Antitumor Effects on Merkel Cell Carcinoma Cell Lines and Mouse Xenografts

40 views | Jul 09 2020

Bin Fang et al. provided compelling preclinical evidence for application of copanlisib in advanced MCC with aberrant PI3K activation for which immunotherapy was insufficient, or patients who were unsuitable for immunotherapy. [Read the Full Post]

Copanlisib for the Treatment of Adults With Relapsed Follicular Lymphoma

41 views | Jul 09 2020

Massimo Magagnoli et al. found that teatment with copanlisib results in clinically relevant and durable responsed in heavily pretreated patients with relapsed or refractory FL. [Read the Full Post]

The Dual PI3Kδ/CK1ε Inhibitor Umbralisib Exhibits Unique Immunomodulatory Effects on CLL T Cells

62 views | Jul 08 2020

Kamira Maharaj et al. suggested that the improved safety profile of umbralisib was due to its role as a dual PI3Kδ/CK1ε inhibitor that preserved Treg number and function. [Read the Full Post]

Effect of Morphology on the Photoelectrochemical Performance of Nanostructured Cu2O Photocathodes

58 views | Jul 05 2020

Lian C T Shoute found that although different deposition methods showed a similar average photocurrent density 2.8±0.3 mA/cm2 at 0 V vs RHE, large variations in the photocurrent density were observed for samples prepared under nominally identical deposition methods. [Read the Full Post]
