OCT4-mediated transcription confers oncogenic advantage for a subset of gastric tumors with poor clinical outcome.

Deregulated transcription programs and signaling pathways are the critical factors involved in the process of carcinogenesis. Signaling pathway-based classification of tumors is expected to pave the way for the development of targeted therapeutics. We investigated the OCT4-mediated transcription program in the gene expression profiles of 939 gastric tumor samples.

Identification of the targeted therapeutic potential of doxycycline for a subset of gastric cancer patients.

The identification of new drugs for the targeted therapy of gastric cancer remains an important need. The RAS/RAF/MEK/ERK/ELK1 signaling cascade is activated in many cancers, including gastric cancer. To identify the targetable inhibitors of the ERK/MAPK pathway, we performed a repurposing screening of a panel of antimicrobial agents in gastric cancer cells using an ERK/MAPK-driven firefly luciferase reporter assay.
