Aberrant SUMOylation Restricts the Targetable Cancer Immunopeptidome

Advanced Science, EarlyView.
Pharmacological SUMOylation inhibition (SUMOi) counteracts tumor immune evasion by unmasking an immunogenic HLA‐I peptide and neoepitope repertoire. By restoring HLA‐I ligand availability through increased antigen processing and presentation, enhanced proteasomal cleavage, and modulated TAP1 peptide affinity, SUMOi boosts tumor immunogenicity ...

Regulation of alphaherpesvirus infections by the ICP0 family of proteins [PDF]

, 2013
Immediate-early protein ICP0 of herpes simplex virus type 1 (HSV-1) is important for the regulation of lytic and latent viral infection. Like the related proteins expressed by other alphaherpesviruses, ICP0 has a zinc-stabilized RING finger domain that ...

Fibrates Inhibit PLTP‐induced M2 Macrophage Infiltration and Increase the Sensitivity of Hepatocellular Carcinoma to ICIs

Advanced Science, EarlyView.
Phospholipid transfer protein(PLTP) plays a critical role in forming a complex with kinase A (AURKA) and P65. This interaction facilitates phosphorylation of P65 at Ser536, leading to the activation of the NF‐κB signaling pathway. Ultimately, this leads to the upregulation of downstream cytokines, including IL‐6, IL‐8, and CSF‐1, which promotes M2 ...

VCP-dependent muscle degeneration is linked to defects in a dynamic tubular lysosomal network in vivo. [PDF]

, 2015
Lysosomes are classically viewed as vesicular structures to which cargos are delivered for degradation. Here, we identify a network of dynamic, tubular lysosomes that extends throughout Drosophila muscle, in vivo. Live imaging reveals that autophagosomes

Dual Targeting of Mutant p53 and SNRPD2 via Engineered Exosomes Modulates Alternative Splicing to Suppress Ovarian Cancer

Advanced Science, EarlyView.
Mutant p53 drives oncogenic splicing to promote the progression of ovarian cancer by partnering with the spliceosome factor SNRPD2. Therefore, it is engineered iRGD‐exosomes to co‐deliver siRNAs against both targets. This approach restored tumor‐suppressive mRNA isoforms, effectively enhanced sensitivity to cisplatin, and ultimately blocked tumor ...

VAPB/ALS8 interacts with FFAT-like proteins including the p97 cofactor FAF1 and the ASNA1 ATPase [PDF]

, 2014
BACKGROUND: FAF1 is a ubiquitin-binding adaptor for the p97 ATPase and belongs to the UBA-UBX family of p97 cofactors. p97 converts the energy derived from ATP hydrolysis into conformational changes of the p97 hexamer, which allows the dissociation of ...

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis

Advanced Science, EarlyView.
This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...

Proteasome activity maintains cell-type-specific gene expression

Cell Reports
Summary: Regulated proteolysis in eukaryotes relies on the ubiquitin-proteasome system, which is critical to myriad cellular functions, including protein quality control, cell cycle regulation, and DNA repair.

Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Deubiquitinating Proteases in Plasmodium falciparum [PDF]

, 2011
Plasmodium falciparum is the blood-borne parasite responsible for the deadliest form of human malaria, a disease that kills up to two million people each year (1).
