12. The MLH1-93 AA genotype is significantly associated with promoter hypermethylation and MLH1 loss in the context of Sessile serrated adenoma of dysplasia. BRAF mutant microsatellite stable colorectal cancers with the AA genotype most likely arise in traditional serrated adenomas since the A allele does not predispose to methylation in this context. PMID: 29304767

34. Promoter methylation and loss of protein expression of hMLH1 are not parallel processes that occur concurrently. hMLH1 methylation is an early molecular event which occurs even in hyperplastic polyps (HPs). the loss of hMLH1 protein expression does not necessarily precede the development of cytological dysplasia in sessile serrated lesion (SSL). PMID: 26713412

36. MLH1, a key protein involved in mismatch repair (MMR), suppresses telomeric sequence insertion (TSI) at intra-chromosomal regions. The frequency of TSI can be elevated by double-strand break (DSB) inducer and abolished by ATM/ATR inhibition. Suppression of TSI requires MLH1 recruitment to DSBs, indicating that MLH1's role in DSB response/repair is important for suppressing TSI. PMID: 28180301

43. Data suggest that yeast Mlh1-Mlh3 heterodimer does not exhibit hallmarks of a canonical (structure-selective) Holliday junction resolvase/endonuclease; multiple Mlh1-Mlh3 heterodimers appear to load onto DNA to form an activated polymer that cleaves DNA; human MLH1-PMS2 exhibits similar characteristics. (MLH = mutL homolog protein; PMS2 = post meiotic segregation increased 2 protein) PMID: 28453523

48. demonstrates that lower level of histone acetylation and specific histone methylation such as H3K36me3 correlate with aberrant transcripts in hMLH1 exon 10-11 region PMID: 28381181
