The most common mutations in the MMR system itself are
MLH1, MSH2 and MSH6 mutations.
(27) A clinical trial on 40 patients with type 2 diabetes mellitus (35-68 years) showed that consumption of probiotic soy milk (PSM) can decrease promoter methylation in proximal and distal
MLH1 promoter region, indicating a possible role for PSM in diabetes management.
And it is confirmed by genetic analysis: the determination of the primary DNA sequence of MMR genes (
MLH1, MLH2, and MSH6).
The genes containing very highly selective SNPs with p-value <0.01 (nearly top 1% SNPs) in all traits and p-value <0.001 (nearly top 0.1%) in any traits were phosphodiesterase 4B (PDE4B), serine/threonine kinase 40 (STK40), collagen, type XI, alpha 1 (COL11A1), ephrin-A1 (EFNA1), netrin 4 (NTN4), neuron specific gene family member 1 (NSG1), estrogen receptor 1 (ESR1), neurexin 3 (NRXN3), spectrin, beta, non-erythrocytic 1 (SPTBN1), ADP-ribosylation factor interacting protein 1 (ARFIP1), mutL homolog 1 (
MLH1), transmembrane channel-like 7 (TMC7), carboxypeptidase X, member 2 (CPXM2), and ADAM metallopeptidase domain 12 (ADAM12).
In a study on the model of rat xenograft, shown that treatment with low dose decitabine causes the gene
MLH1 reactivate (Plumb, 2000).
Moreover, the
MLH1 gene has a p53-response element, indicating that it is regulated by p53 (Kaplan and Gunduz 2012).
2012) using a lookup approach in our data set for DAPK1, CDKN2A (P16), GMDS, C10orf32/AS3MT, RASSF1, PPARG, TP53, and
MLH1 (see Supplemental Material, Table S3).
The Rmax of 6.49
mLh1 was observed for the treatment by 0.6 gL-1
Vitamin and antioxidant rich diet increases
MLH1 promoter DNA methylation in DMT2 subjects.
Lab-based analyses beyond the usual diagnosis based on light microscopic examination of H&E stained slides--immunohistochemistry and PCR-based assays such as sequencing, mutation testing, microsatellite instability analysis, and determination of
MLH1 methylation--are most helpful for guiding diagnosis and treatment of endometrial cancer [29].
