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]

New insights into estrogenic regulation of O6-methylguanine DNA-methyltransferase (MGMT) in human breast cancer cells: Co-degradation of ER-α and MGMT proteins by fulvestrant or O6-benzylguanine indicates fresh avenues for therapy

732 views | Jun 29 2017

Paranjpe A et al. concluded that MGMT and ER-α proteins exist as a complex and are co-targeted for ubiquitin-conjugation and subsequent proteasomal degradation. The findings offer a clear rationale for combining alkylating agents with endocrine therapy. [Read the Full Post]

miR-17-5p down-regulation contributes to erlotinib resistance in non-small cell lung cancer cells

2214 views | Jun 29 2017

Zhang W et al. indicated that miR-17-5p down-regulation contributes to erlotinib resistance of NSCLC by modulating its target genes such as EZH1 and plasma miR-17-5p might be a potential biomarker of erlotinib response in NSCLC patients [Read the Full Post]

Impact of CTLA-4 blockade in conjunction with metronomic chemotherapy on preclinical breast cancer growth

1417 views | Jun 28 2017

Parra K et al. proved Sequential therapy of anti-CTLA-4 followed by gemcitabine is effective in chemotherapy-naive tumours, although tumour relapses can occur, in some cases accompanied by the development of spontaneous metastases. [Read the Full Post]

Amplification of EGFR Wild-Type Alleles in Non-Small Cell Lung Cancer Cells Confers Acquired Resistance to Mutation-Selective EGFR Tyrosine Kinase Inhibitors

2871 views | Jun 27 2017
