The role of histone post-translational modifications in cancer and cancer immunity: functions, mechanisms and therapeutic implications

Frontiers in Immunology
Histones play crucial roles in both promoting and repressing gene expression, primarily regulated through post-translational modifications (PTMs) at specific amino acid residues.

Anticodon Engineered Transfer RNA (tRNASUAG) Inhibits Hepatitis B Virus Replication by Promoting the Degradation of Core Protein

Advanced Science, EarlyView.
This study employed tRNASUAG, an anticodon‐engineered tRNA (ACE‐tRNA), to introduce a phosphorylatable serine into the C‐terminal domain of HBc by reading through its stop codon, thereby potentially promoting the ubiquitin‐proteasome degradation of HBc, and subsequently inhibiting HBV replication. Through a tRNASUAG‐gHBV1‐tRNASUAG‐gHBV2‐tRNASUAG tandem

Hypoxia and hypoxia mimetics differentially modulate histone post-translational modifications

Epigenetics, 2021
Post-translational modifications (PTMs) to the tails of the core histone proteins are critically involved in epigenetic regulation. Hypoxia affects histone modifications by altering the activities of histone-modifying enzymes and the levels of hypoxia ...

Characterisation of peanut allergens and possible post-translational modifications (PTMs) [PDF]

, 2018
BackgroundPeanut allergy is the most common type of food allergy causing severe reactions or even fatal anaphylaxis in sensitised individuals. The major peanut allergens are Ara h 1, Ara h 2, Ara h 3, and Ara h 6 which cause the most severe responses. Their molecular properties have been characterised but possible post-translational modifications (PTMs)

Histone Lactylation‐Driven Upregulation of VRK1 Expression Promotes Stemness and Proliferation of Glioma Stem Cells

Advanced Science, EarlyView.
Glioblastoma (GBM) is the most aggressive primary brain tumor, with glioma stem cells (GSCs) driving treatment resistance. This study reveals that lactate promotes histone lactylation (H3K18la) at the VRK1 promoter, regulating GSC stemness and proliferation via the H3K18la/VRK1/YBX1/SOX2 pathway. The VRK1‐targeted nanoliposome A/TMZ‐siVRK1 demonstrates

Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

Advanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

GSK461364 Inhibits NLRP3 Inflammasome by Targeting NEK7 Phosphorylation

Advanced Science, EarlyView.
Schematic diagram of the mechanism by which GSK461364 inhibits NLRP3 inflammasome activation. GSK461364 inhibits the phosphorylation of NEK7 likely at serine 221 and serine 260 by suppressing the activity of PLK1, thereby restraining the formation of the NLRP3 inflammasome.
