In this content, a small molecular ligand of prostate specific membrane antigen (SMLP) conjugated poly (caprolactone) (PCL)-b-poly (ethylene glycol) (PEG) copolymers with different block lengths were synthesized to construct a satisfactory drug delivery system. Four different docetaxel-loaded polymeric micelles (DTX-PMs) were prepared by dialysis with particle sizes less than 60 nm as character...

Hereditary non-polyposis colorectal cancer (HNPCC) is the commonest form of inherited colorectal cancer (CRC) predisposition and by definition describes families which conform to the Amsterdam Criteria or reiterations thereof. In ~50% of patients adhering to the Amsterdam criteria germline variants are identified in one of four DNA Mismatch repair (MMR) genes MLH1, MSH2, MSH6 and PMS2. Loss of ...

Function MSH2 can bind to MSH6 or to MSH3 to form the MutS alpha or the MutS beta complexes respectively. While MutS alpha complex binds to base-base and insertion-deletion mismatches, MutS beta only binds to insertion-deletion mismatches. Upon binding to the mismatch, the MutS complex associates with the MutL complex (composed of MLH1 and PMS2), and recruits the proteins needed for DNA excisio...

Epigenetic silencing of tumour suppressor genes has been observed in various cancers. Looking at hepatocellular carcinoma (HCC) specific protein silencing was previously demonstrated to be associated with the Hepatitis C virus (HCV). However, the proposed HCV dependent promoter methylation of DNA mismatch repair (MMR) genes and thereby enhanced progression of hepatocarcinogenesis has been the s...

Interference-dependent crossing over in yeast and mammalian meioses involves the mismatch repair protein homologs MSH4-MSH5 and MLH1-MLH3. The MLH3 protein contains a highly conserved metal binding motif DQHA(X)2E(X)4E that is found in a subset of MLH proteins predicted to have endonuclease activities (KADYROV et al. 2006). Mutations within this motif in human PMS2 and S. cerevisiae PMS1 disrup...

Abstract Multiple large-scale genomic studies across pediatric tumors have reported an overall frequency of ~6-10% patients with constitutional pathogenic variants, but associations cancer predisposition distinct tumor types vary between zero and 100%. We analyzed sequencing DNA methylation data from 363 to explore the landscape in high-grade gliomas (pedHGG). Almost all pedHGG alterations resu...
