Reduction of the Mlh1 protein level leads to defective oocytes that fail to complete embryogenesis after fertilization thereby reducing female fertility.
Results suggest that Xenopus MBD4/MLH1 participates in a novel G2 checkpoint that is responsive to DNMT1p levels in developing embryos and cells.
Male mlh1 mutants are sterile and display an arrest in spermatogenesis at metaphase I, resulting in increased testis weight due to accumulation of prophase I spermatocytes.
In zebrafish mlh1 mutant (knock-out) males, a delay of both meiotic divisions occurs rather than complete arrest during meiosis I. Eggs fertilized with mutant sperm develop as malformed embryos and are aneuploid.
Identification and characterization of novel knockout mutants of the three major MMR genes, mlh1, msh2, and msh6, in zebrafish that develop tumors at low frequencies.

radiation exposure could further increase the risk of colorectal carcinogenesis induced by inflammation under the conditions of Mlh1 deficiency.
these data identify Mlh1 and Mlh3 as novel critical genetic modifiers of HTT CAG instability, point to Mlh1 genetic variation as the likely source of the instability difference in B6 and 129 strains

Down-regulation of MLH1 is associated with initiation and growth of neuroblastoma and brain tumour multicellular spheroids.
MLH1 can convert DNA nicks and point mutations into double-stranded DNA breaks for both core nonhomologous end-joining factors and alternative end-joining pathways of class-switch recombination.
Data show that the constitutive inactivation of MLH1, resulting Mlh1(Deltaex4/Deltaex4) mouse line, displays complete MMR deficiency and a cancer predisposition phenotype similar to Mlh1-/- mice.
Ablation of Mlh1 did not appreciably influence the developmental phenotypes conferred by the absence of Rad51d.
Role for mismatch repair proteins Msh2, Mlh1, and Pms2 in immunoglobulin class switching shown by sequence analysis of recombination junctions.
In this study, we investigated whether failure to develop foci of MLH1 protein on chromosomes in prophase would lead to elimination of prophase spermatocytes.Thus, spermatocytes are not eliminated in direct response to the initial meiotic defect
We found that MLH1 and PMS2 have functional nuclear localization signals (NLS) and nuclear export sequences, yet nuclear import depended on their C-terminal dimerization to form MutLalpha
Mlh1 can function in antibody class switch recombination independently of Msh2.
Mlh1 deficiency accelerates myeloid leukemogenesis in neurofibromatosis 1 (Nf1) heterozygous mice.These results suggest that MMR deficiency can accelerate myeloid leukemogenesis in Nf1+/- mice, presumably by inactivating Nf1 gene expression.
The cellular content of MLH1 protein seems to be critical for determining if damaged cells enter into either a death or mutation-inducing pathway.
Mlh1 modulates error-prone nonhomologous end-joining by inhibiting the annealing of DNA ends containing noncomplementary base pairs or by promoting the annealing of microhomologies.
Repression of MLH1 is associated with precancerous conditions in hyperplastic mucosa adjacent to colon cancer
Report loss of MSH2 and MSH6 expression in sporadic deficient mismatch repair colorectal cancer due to MLH1 promoter hypermethylation.
MLH1 constitutional hypermethylation is associated with Lynch syndrome.
Results show that among MLH1 mutation carriers, mutations in MLH1 were associated with colorectal cancer in 61% of men and women; endometrial cancer in 27% women; and ovarian cancer in 8% of women in a cohort of patients diagnosed with Lynch syndrome. When stratified by mutation type, women with truncating MLH1 mutations had later age of onset of endometrial cancer than those with non-truncating mutations.
This is the largest cohort of patients with MLH1 secondary epimutations associated with a broad spectrum of genetic defects. This study provides further insight into the complexity of molecular mechanisms leading to secondary epimutations.
Study identified that MLH1 can be post-translationally phosphorylated at multiple sites but most dominantly at position S477. Phosphorylation of MLH1 at position S477 is managed by CK2 switching off DNA mismatch repair activity in vitro.
P.K618del variant in MLH1 is a pathogenic mutation.
Study indicated that MLH1 plays an important role in improving the cisplatin sensitization of endometrial carcinoma cells through activation of the MLH1/c-Abl signaling pathway in vitro.
Report substitution of one base-pair in exon 1 of MLH3 (c.1397C>A) and a frameshift mutation in exon 19 of MLH1 (c.2250_2251ins AA) in a 43-year-old Chinese male with a Lynch syndrome pedigree, including his mother. maternal grandmother and maternal uncle.
A novel heterozygous germline mutation (c.3G>T, p.Met1Ile) in MLH1 gene was discovered by next generation sequencing.
Mutational analysis of the MLH1/MSH2 genes was carried out. Analysis was extended to the family members and the general population. This led to the identification of a heterozygous frameshift duplication in the MLH1 gene at position 910 (c.910dupG). Three siblings had inherited the mutation from their mother, two of whom were asymptomatic at the time of diagnosis.
Lynch syndrome associated MLH1 c.2059C>T mutation is a Swedish founder mutation with a probable origin in a single founder individual in the north of Sweden, whose descendants have migrated southwards in Sweden as well as across the border to Finland.
Inconsistent with previous meta-analyses, this meta-analysis shows that the hMLH1 655A>G and 1151T>A polymorphisms might be risk factors for colorectal cancer. Moreover, the -93G>A polymorphism is associated with the susceptibility of colorectal cancer in Asian population.
Hypomethylation of MLH1 gene is associated with chemotolerance of breast carcinoma.

The DNA mismatch repair gene (MMR) plays an important role in anti-carcinogenesis and MMR gene deficiency.
Study investigated the counteraction of oxidative stress by vitamin E in the colorectal cancer cell line Caco-2 under normal and high glucose cell culture condition. Gene expression and promoter methylation of the DNA repair gene MutL homolog 1 (MLH1) and the DNA methyltransferase 1 (DNMT1) were investigated. Induction of MLH1 and DNMT1 gene expression was noticed, accompanied by an increase in global methylation.
the results identified for the first time a MLH1 missense mutation (NM_000249.3:p.Tyr379Ser/c.1136A>C) in a Chinese family with Gardner syndrome (GS), thus broadening the range of mutated genes associated with GS.

Meiosis progression and female age affect expression profile of DNA repair MLH1 gene in bovine oocytes.
This gene was identified as a locus frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). It is a human homolog of the E. coli DNA mismatch repair gene mutL, consistent with the characteristic alterations in microsatellite sequences (RER+phenotype) found in HNPCC. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional transcript variants have been described, but their full-length natures have not been determined.
