The NTHL1 gene encodes DNA glycosylase, which is involved in base excision repair, and biallelic mutations of this gene result in NTHL1-associated polyposis (NAP), a hereditary disease characterized by colorectal polyposis and multiple types of carcinomas.
We observed inconsistent conclusions regarding the genetic role of glutathione S-transferase gene polymorphisms, including glutathione S-transferase M1 (<i>GSTM1</i>), glutathione S-transferase T1 (<i>GSTT1</i>) present/null, and glutathione S-transferase pi <i>(GSTP1</i>) Ile105Val polymorphisms, in the susceptibility to nasal or colorectal polyposis (NP or CP).
CRC group had much more MVD in comparison with normal group and colorectal polyps group (P < 0.05).When compared with negative group, MVD was significantly higher than that in CRC tissue with positive HGF and FAP (P < 0.05).
The C/C genotype of MTHFRrs1801131 is more likely to be a genetic risk factor for colorectal polyps in the UK region, although this finding should be verified with a larger sample size.
Validation studies showed that SETD7 expression increased from healthy controls to those with colorectal polyps and finally CRC patients, and decreased after surgery.
In this case-control study, FBLN1 and STK31 serum levels were measured in 120 participants; 49 CRC patients (group I), 26 patients with benign colorectal polyps (group II) and 45 healthy controls (group III).

We used immunohistochemistry to evaluate CD133 expression in 200 endoscopically resected colorectal polyps from 200 patients and 20 normal mucosae between January 1993 and December 1996.
Through germline multigene panel testing, we discovered the co-occurrence of Lynch syndrome due to a PMS2 mutation and juvenile polyposis syndrome due to a BMPR1A mutation in a young man with synchronous bladder and colorectal cancers and a family history of colorectal polyps.
Quantitative real-time PCR was used to detect the expression of ATM and PUMA in tumor tissue and adjacent healthy tissue of 67 patients with colorectal cancer and in normal colorectal tissue of 33 patients with colorectal polyps at mRNA level.
In the present study, we revealed the susceptible population and risk factors of colorectal polyps, and analyzed the expression of Ki-67, p53 and K-ras in the intestinal mucosa of patients with colorectal polyps in order to explore their significance in the detection and prognosis of CRC at an early stage.

A large body of evidence from preclinical studies indicates that expression of the estrogen receptor beta (ERβ/ESR2) demonstrates an inverse relationship with the presence of colorectal polyps and stage of tumors, and can mediate a protective response.
