β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Lysine l-lactylation is the dominant lactylation isomer induced by glycolysis

Nature Chemical Biology
AbstractLysine l-lactylation (Kl-la) is a novel protein posttranslational modification (PTM) driven by l-lactate. This PTM has three isomers: Kl-la, N-ε-(carboxyethyl)-lysine (Kce) and d-lactyl-lysine (Kd-la), which are often confused in the context of the Warburg effect and nuclear presence. Here we introduce two methods to differentiate these isomers:

Unveiling Lactylation: A Novel Frontier in Cancer Stemness and Therapy

Advanced Science, EarlyView.
Tumor metabolism and epigenetic regulation are intrinsically linked. This review highlights lactylation as a pivotal bridge connecting these processes, acting as an active epigenetic effector in cancer stemness. We delineate how lactylation orchestrates the cancer stem cell landscape and evaluate its regulatory networks.

Epigenetic Silencing of RFX7 Defines a Transcriptional Axis Linking Lactate Metabolism to Immune Checkpoint Therapy in Glioblastoma

Advanced Science, EarlyView.
Glioblastoma (GBM) exhibits RFX7 silencing via promoter hypermethylation, which downregulates PIK3IP1 to activate PI3K/AKT signaling, increase lactate accumulation, and enhance histone H4K12 lactylation. This lactylation upregulates PD‐L1/CSF1 expression and drives the immunosuppressive microenvironment formation.

Lactylated Proteomic Analysis Reveals Functional Implications of Lysine Lactylation In Asthenozoospermia

Molecular & Cellular Proteomics
The mechanism underlying asthenozoospermia in male infertility has been a prominent topic in reproductive medicine research. Human sperm function is modified by various protein post-translational modifications (PTMs). Among these, lactylation modification, a relatively novel PTM, has not been previously reported in the context of the male reproductive ...
