Refs

PCK2 K100

Ubiquitination

Prevent Parkin-mediated polyubiquitination of OXSM

LT

[44]

H3K18la

m6A modification and acetylation

Promote m6A-modified NEAT1 stability, activate SCD by histone acetylation

HCC

[45]

H3K18la

m6A modification

Promote METTL3-mediated SCD1 m6A levels

NAFLD

[48]

H3K18la

m6A modification

Promote METTL3-mediated m6A modification on ACSL4

ALI

[72]

HADHA K519

Methylation

KDM6B-mediated HADHA demethylation/ lactylation regulates cementogenesis

Periodontitis

[62]

NSUN2 K508

m5C modification

Promote GCLC m5C formation

GC

[75]

Mecp2 K271la

Methylation

Exercise ameliorates atherosclerosis via Mecp2 k271la-H3k36me3/RUNX1

Atherosclerosis

[124]

AMPKα lactylation

Phosphorylation

AMPKα lactylation inhibits its phosphorylation

IVDD

[134]

H3K18la

ACSL4 lactylation

H3K18la promotes ACSL4 transcription, while lactate directly stimulates non-histone lactylation of ACSL4 at K412

IVDD

[73]

H3K18la

MTCH2 acetylation

H3K18la-induced ACAT2 transcription promotes MTCH2 K100 acetylation, which disrupts OXPHOS and establishes a positive feedback loop

PC

[84]

SPRING lactylation

Phosphorylation

pPCK1 binds to and phosphorylates LDHA, further promoting SPRING lactylation at K82 and thereby enhancing MVA pathway activity

ICC
