USP45 Represses Melanoma Development by Deubiquitinating and Stabilizing Tumor Suppressor MRGPRF

Advanced Science, EarlyView.
USP45 acts as a melanoma suppressor by stabilizing MRGPRF, which weakens the PI3K/AKT pathway, suppresses tumor growth, and reduces melanoma cell migration and invasion. Abstract Melanoma, a highly malignant skin cancer, has seen a rising incidence and death toll. MRGPRF is a novel melanoma suppressor that inhibits the PI3K/AKT pathway.

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.

Recent Development of Genetic Code Expansion for Posttranslational Modification Studies

Molecules, 2018
Nowadays advanced mass spectrometry techniques make the identification of protein posttranslational modifications (PTMs) much easier than ever before. A series of proteomic studies have demonstrated that large numbers of proteins in cells are modified by

Posttranslational modification and microtubule stability. [PDF]

The Journal of cell biology, 1987
We have probed the relationship between tubulin posttranslational modification and microtubule stability, using a variation of the antibody-blocking technique. In human retinoblastoma cells we find that acetylated and detyrosinated microtubules represent congruent subsets of the cells' total microtubules.

Hypoxia‐Induced circPRELID2 Promotes Gastric Cancer Metastasis by Facilitating ZEB2 Translation via PCBP1 O‐GlcNAcylation

Advanced Science, EarlyView.
Under hypoxia, HIF1A is directly bound to the PRELID2 promoter to increase PRELID2 pre‐mRNA expression, followed by the DYRK1A–SFPQ–SAM68 complex binding to Alu‐containing introns in PRELID2 pre‐mRNA, leading to circPRELID2 circularization. CircPRELID2 interacts with PCBP1 and promotes its cytoplasmic retention.

ZDHHC12 Palmitoylates HDAC8 to Promote the Progression of Hepatocellular Carcinoma Associated with a Diet High in Saturated Fatty Acids

Advanced Science, EarlyView.
This study identifies ZDHHC12 as a critical mediator of PA‐induced HCC progression. Mechanistically, PA upregulates ZDHHC12 expression through SMARCA4 activation, leading to HDAC8 palmitoylation at Cys244 which blocks HSC70‐mediated lysosomal degradation of HDAC8, thereby promoting HCC development. These findings provide novel mechanistic insights into

ACSS2/AATF Drives Soluble FasL‐Mediated CD8+ T Cell Apoptosis in Pancreatic Neuroendocrine Tumors

Advanced Science, EarlyView.
This study unveils that ACSS2‐driven acetate metabolism fuels histone pan‐acetylation in pancreatic neuroendocrine tumors (PNETs), remodeling the epigenetic landscape. The ACSS2/AATF axis transcriptionally activates soluble FasL (sFasL), which engages Fas receptors on infiltrating CD8+ T cells to trigger caspase‐8/3‐mediated apoptosis.

METTL10‐Mediated PIAS3 Methylation Links Purine Metabolism to Gastric Cancer Progression

Advanced Science, EarlyView.
METTL10‐mediated methylation of PIAS3 at K442 inhibits its SUMO E3 ligase activity toward MITF. This reduces MITF SUMOylation and subsequent RNF4‐mediated ubiquitination, leading to MITF protein accumulation and gastric cancer progression. Abstract Metabolic dysregulation plays a significant role in the development of gastric cancer (GC).

Detecting Posttranslational Modifications of Hsp90 [PDF]

, 2017
The molecular chaperone Heat Shock Protein 90 (Hsp90) is essential in eukaryotes. Hsp90 chaperones proteins that are important determinants of multistep carcinogenesis. The chaperone function of Hsp90 is linked to its ability to bind and hydrolyze ATP.

Gigaxonin Potentiates Antiviral Innate Immune Responses by Targeting cGAS and TREX1

Advanced Science, EarlyView.
TREX1 antagonizes DNA sensor cGAS by degrading cytosolic DNA. This work identifies gigaxonin as a molecular switch that coordinates DNA sensing and clearance pathways to amplify antiviral responses. Under the steady state, gigaxonin maintains cellular homeostasis by mediating TREX1 ubiquitination and proteasomal degradation. During DNA virus infection,
