Mutant p53 proteins counteract autophagic mechanism sensitizing cancer cells to mTOR inhibition

Molecular Oncology, 2016
Mutations in TP53 gene play a pivotal role in tumorigenesis and cancer development. Here, we report that gain‐of‐function mutant p53 proteins inhibit the autophagic pathway favoring antiapoptotic effects as well as proliferation of pancreas and breast ...

TEAD1 Enhances Exosome Secretion and Promotes Exosome‐Mediated Tissue Regeneration

Advanced Science, EarlyView.
TEAD1 functions as a crucial molecular switch regulating exosome secretion in various cell types. TEAD1 enhances exosome secretion by upregulating key proteins associated with exosome secretion, including RAB11, CD9, and SNAP23. This study reveals a novel role for TEAD1 in regulating exosome secretion and tissue regeneration, particularly in diabetic ...

Ufmylation‐Deficient DDRGK1 Ameliorates Obesity by Inhibiting FASN‐Mediated Adipocyte Lipogenesis

Advanced Science, EarlyView.
DDRGK1 regulates de novo lipogenesis via stabilization of fatty acid synthase (FASN). DDRGK1‐mediated UFMylation of FASN prevents its ubiquitin–proteasomal degradation. Reduced DDRGK1 expression or mutation at the key UFMylation site enhances FASN degradation and suppresses fatty acid synthesis (FAS), resulting in smaller adipocytes and improved ...

Bypassing the guardian: regulated cell death pathways in p53-mutant cancers

Cellular & Molecular Biology Letters
Approximately half of all cancers bear mutations in the tumor suppressor p53. Despite decades of research studying p53 function, treatment of p53-mutant cancers remains challenging owing to the effects of p53 mutations on many complex and interrelated ...

UBE2T‐Driven p53 Degradation Rewires Glycolysis to Orchestrate Lactylation‐Mediated CAFs Activation and ECM Deposition in Pancreatic Cancer

Advanced Science, EarlyView.
This study integrates multi‐omics to reveal the critical role of UBE2T in driving malignancy and stromal co‐evolution in PDAC. UBE2T potentiates glycolysis by regulating p53 degradation via a positive feedback loop, thereby promoting histone H3 lysine 18 lactylation in CAFs and stromal deposition. The UBE2T inhibitor PGG represents a potential strategy

GNL3 Orchestrates AR Transcriptional Programs to Drive Castration‐Resistant Prostate Cancer and Immune Evasion

Advanced Science, EarlyView.
GNL3 is a novel AR coregulator with dual coactivator and corepressor functions in prostate cancer (PCa). Our study uncovers a previously unrecognized mechanism by which the AR transcriptional complex integrates oncogenic signaling and immune suppression.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

DNA-delivered monoclonal antibodies targeting the p53 R175H mutant epitope inhibit tumor development in mice

Genes and Diseases
The tumor suppressor p53 is the most common mutated gene in cancer, with the R175H as the most frequent p53 missense mutant. However, there are currently no approved targeted therapies or immunotherapies against mutant p53.

SLC2A3‐Mediated Lactate Metabolism Promotes Lung Cancer Bone Metastasis by Modulating P53 Lactylation and Immune Evasion

Advanced Science, EarlyView.
SLC2A3 derived lactate promotes metastasis through p53 lactylation at K120 and osteoclast differentiation. Pharmacological inhibition of SLC2A3 upregulates PD‐1 expression on CD8+ T cells via lactate induced p53 lactylation, which modulates immune evasion. ABSTRACT Bone metastasis is a devastating consequence of lung cancer.

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

Hepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.
