Lactylation-driven transcriptional activation of FBXO33 promotes gallbladder cancer metastasis by regulating p53 polyubiquitination.

Gallbladder cancer (GBC) is the most common malignant tumor of the biliary tract and is often prone to early distant metastasis. However, the mechanisms underlying GBC's invasive metastasis remain unclear. This study identified that F-box only protein 33 (FBXO33) expression is significantly elevated in GBC and is negatively associated with patient prognosis.

ELL Protein-associated Factor 2 (EAF2) Inhibits Transforming Growth Factor β Signaling through a Direct Interaction with Smad3.

A series of in vitro and in vivo studies has shown that EAF2 can affect multiple signaling pathways involved in cellular processes. However, the molecular mechanisms underlying its effects have remained elusive. Here we report the discovery of a new functional link between EAF2 and TGF-β signaling.

PELP1 suppression inhibits colorectal cancer through c-Src downregulation.

Proline-, glutamic acid-, and leucine-rich protein 1 (PELP1), a coregulator of estrogen receptors alpha and beta, is a potential protooncogene implicated in several human cancers, including sexual hormone-responsive or sexual hormone-nonresponsive cancers. However, the functions of PELP1 in colorectal cancer remain unclear. In this study, western blot and bioinformatics revealed that PELP1 expression was higher in several colorectal cancer cell lines than in immortalized normal colorectal epithelium.
