YWK-II/APLP2 inhibits TGF-β signaling by interfering with the TGFBR2-Hsp90 interaction.

Transforming growth factor-β (TGF-β) regulates multiple cellular biological processes by activating TGF-β type I receptors (TGFBR1) and type II receptors (TGFBR2), and Hsp90 stabilizes these receptors through specific interactions. In many malignancies, one of the most deregulated signaling pathways is the TGF-β signaling pathway, which is often inactivated by mutations or deregulation of TGF-β type II receptors (TGFBR2). However, the molecular mechanisms are not well understood.

GRSF1 predicts an unfavorable prognosis and promotes tumorigenesis in lung adenocarcinoma based on bioinformatics analysis and validation.

Background: Effective biomarkers play a critical role in improving clinical approaches to treat lung adenocarcinoma (LUAD). However, many existing biomarkers have limitations due to a lot of factors, requiring the development of additional biomarkers to effectively predict the disease course and prognosis of LUAD. Guanine-rich RNA sequence binding factor 1 (GRSF1) participates in multiple biological processes, but its regulatory effect on LUAD remains unknown.

RING finger 138 deregulation distorts NF-кB signaling and facilities colitis switch to aggressive malignancy.

Prolonged activation of nuclear factor (NF)-кB signaling significantly contributes to the development of colorectal cancer (CRC). New therapeutic opportunities are emerging from targeting this distorted cell signaling transduction. Here, we discovered the critical role of RING finger 138 (RNF138) in CRC tumorigenesis through regulating the NF-кB signaling, which is independent of its Ubiquitin-E3 ligase activity involved in DNA damage response.

PDCD6 cooperates with C-Raf to facilitate colorectal cancer progression via Raf/MEK/ERK activation.

Background: Colorectal cancer (CRC) is one of the most common malignancies, and it's expected that the CRC burden will substantially increase in the next two decades. New biomarkers for targeted treatment and associated molecular mechanism of tumorigenesis remain to be explored. In this study, we investigated whether PDCD6 plays an oncogenic role in colorectal cancer and its underlying mechanism.
