Article Abstract
Lactylation is a novel post-translational modification of proteins, which has attracted extensive attention since its discovery. Lactylation takes lactate, a common metabolite, as its substrate and mediates the modification under the action of lactyltransferases. Although lactylation modification was initially found to undergo in histones, subsequent studies have shown that this novel modification is not limited to specific protein classes, and can undergo in both histone and non-histone proteins. Lactylation has been proved to play an important regulatory role in a variety of diseases, including tumors, metabolic disorders, cardiovascular diseases, and neurodegenerative diseases. Given the tumor properties of its substrate lactate, lactylation has been most extensively studied in tumors, and as a result, we have gained a deeper understanding of the potential molecular mechanisms and regulatory roles of lactylation in tumors. In this paper, we will summarize the regulatory and functional mechanisms of lactylation, explain the cellular processes in which lactylation is involved and its association with various diseases, and look forward to the future clinical application of lactylation.

Background: Protein lactylation has been implicated in stress-responsive cellular mechanisms, yet its role in lung transplantation-associated ischemia-reperfusion injury (IRI) remains undefined.
Methods: Transcriptomic profiles from GSE145989 were analyzed through differential expression analysis (limma) and weighted gene co-expression network analysis (WGCNA). Integrating the identified genes with lactylation-related signatures uncovered key lactylation-related genes (LRGs) as potential targets.

In oxaliplatin-resistant gastric cancer (GC), multi-omics profiling combined with organoid libraries reveals altered metabolic pathways associated with chemoresistance. We identify a novel lactylation modification at K115 of Poly(RC)-binding protein 2 (PCBP2K115la), which confers functional oxaliplatin resistance. Mechanistic studies demonstrate that the long non-coding RNA BASP1-AS1 assembles a complex containing Unc-51 Like Autophagy Activating Kinase 1 (ULK1) and lactate dehydrogenase A (LDHA), thereby activating LDHA enzymatic activity to increase lactate production.

Lung cancer is a common malignancy that poses risks to human health and quality of life. The primary treatment options currently available include surgery, chemotherapy and radiotherapy. However, the aggressive metastatic nature of the disease combined with the development of drug and radiation resistance results in suboptimal survival outcomes.

Preeclampsia (PE) involves complex metabolic-inflammatory interactions, yet the mechanistic links among glycolysis, protein lactylation, and pyroptosis in placental pathogenesis remain undefined. In this study, we explore their tripartite relationship with PE development by combining bioinformatics analysis of PE-associated transcriptomes with experimental validation using placental tissues from PE patients and healthy controls. To elucidate the underlying mechanism, we utilize models involving hypoxic endothelial cell cultures, pharmacological glycolysis inhibition via 2-deoxyglucose, and genetic modulation of hexokinase 2 (HK2) expressions through siRNA silencing and plasmid-based overexpression.

Lactate, as an end-product of glycolysis, has been considered as a metabolic waste that participates in a few physiological functions. Recently, a novel study by Zhao's laboratory reported that lactate can serve as an epigenetic modification substrate, causing histone or nonhistone lysine residues to undergo lactylation, which then regulates gene transcription, translation, and protein function. Subsequent studies confirmed that lactylation plays an important role in a series of physiological and pathological processes, such as inflammation, cancer, and other biological processes.
