Alternative polyadenylation of ZEB1 promotes its translation during genotoxic stress in pancreatic cancer cells [PDF]
, 2017 Pancreatic ductal adenocarcinoma (PDAC) is characterized by extremely poor prognosis. The standard chemotherapeutic drug, gemcitabine, does not offer significant improvements for PDAC management due to the rapid acquisition of drug resistance by patients.

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Post-translational Processing of RhoA
Journal of Biological Chemistry, 1997 RhoA and related GTP-binding proteins are modified post-translationally at their carboxyl terminus to form a prenylcysteine methyl ester. The synthesis and post-translational modification of RhoA and Cdc42 were examined in the RAW264 macrophage cell line,

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Role of RNA Interference (RNAi) in the Moss Physcomitrella patens [PDF]
, 2013 RNA interference (RNAi) is a mechanism that regulates genes by either transcriptional (TGS) or posttranscriptional gene silencing (PTGS), required for genome maintenance and proper development of an organism.

Post‐Translational Processing of Rat Ribosomal Proteins [PDF]
European Journal of Biochemistry, 1997 The complete amino acid sequences of rat and yeast (Saccharomyces cerevisiae) ribosomal proteins derived from precursors containing an N‐terminal ubiquitin or ubiquitin‐like sequence (C‐terminal extension proteins or CEPs) were determined and investigated for any post‐translational modifications by reverse‐phase HPLC purification, direct amino acid ...

Molecular Oncology, EarlyView.Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve
