Target Information

Background

Histones, fundamental proteins involved in chromatin structure and gene regulation, are subject to a wide array of enzyme-catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitination, and numerous others. Histone L-lactylation, a recently discovered post-translational modification induced by lactate has emerged as a significant addition to this repertoire. The extent and dynamics of this modification are highly reliant on lactate levels within the cellular microenvironment and can be modulated through the introduction of extracellular lactate in cultured cells or the stimulation of intracellular glycolysis. The introduction of lysine L-lactylation is mediated by the acetyltransferase p300, while the removal of lactylation marks from histones has been attributed to Class I histone deacetylases (HDAC 1-3). Histone lactylation has been implicated in various biological processes, including inflammation, fibrosis, differentiation, and cancer progression.

Description: Chromatin immunoprecipitations were performed with 6 μg of normal rabbit IgG as a negative control. The immunoprecipitated DNA was quantified by real-time PCR using primers specific for the human GAPDH CDDS, RPL30, LDHA promoter, LDHA CDS, FOXO3a promoter, FOXO3a downstream, RAB20, and TUBBP10 regions. The data are presented as enrichment of each sample relative to the total amount of input at each amplicon.

Description: CUT&Tag was performed with Anti-L-Lactyl-Histone H4 (Lys8) Rabbit mAb (PTM-1415RM) alongside normal rabbit IgG as a negative control. The resulting DNA was sequenced on the Illumina NovaSeq platform with paired-end reads of 150 bp and a sequencing depth of 3 million reads. The figure shows significant H4K8la signal enrichments at the promoter regions of CD9, PLEKHG6, LTBR, and GAPDH.
