Abstract
Objective: The aim of study was to investigate the association of IL 1B gene polymorphism with involvement of H. pylori and other gastric diseases. Methods: Blood samples of dyspeptic patients were collected from endoscopy department of Allied Hospital Faisalabad from January 2017 to January 2019 and were qualitatively assayed for serological detection of CagA H. pylori antibodies. PCR followed by direct sequencing was performed for proinflammatory IL-1B gene polymorphism detection. Sequence analysis was performed in software SnapGene viewer for haplotypes. Results: Demographic characteristics of seropositive patients showed maximum 25% gastritis in age groups of 20-40 years and 41-60 years, predominantly (41.7%) in females. While in seronegative patient’s gastritis (33.3%) was found in age group of 20-40 years mainly in males (41.7%). Among studied groups, higher expression of IL-1B-511 genotype (33.3%) polymorphism was found in healthy individuals as compared to H. pylori seropositive (25%) and seronegative (8.3%). While IL-1B-31 genotype showed maximum 33.3% polymorphism rate in seropositive gastric diseased group. Moreover, haplotypes frequencies IL-1B-511CC and IL-1B-31TT were predominantly (20%) found in seropositive gastric diseased group. Conclusions: In H. pylori seropositive patients, gastric disease was commonly found, however, gastric disease was not only associated with H. pylori as seronegative patients were also carrying gastric complications. Interleukin IL-1B polymorphism was partially associated with H. pylori infection in studied dyspeptic population.

Abstract
BACKGROUND While gastric cancer is a common cancer in the world and Iran, its molecular mechanisms are not fully understood as yet. Epigenetic modifications can lead to alteration of gene expression and development of tumorigenesis mechanisms. METHODS To clarify the difference in DNA methylation pattern of histological types in gastric carcinoma, CpG islands in the promoters of retinoic acid receptor β gene (RAR-β) was studied using methylation-specific PCR. RESULTS In gastric cancer tissues, hypermethylation frequency of RAR-β gene was respectively 61 and 33% for diffuse and intestinal type. In diffuse type, hypermethylation of RAR-β has been significantly associated with invasion (P= 0.007), differentiation (P= 0.033) and location (P= 0.012) of the tumor. However, hypermethylation of RAR-β correlated only with tumor size (P= 0.029) in intestinal type. For adjacent non-tumor samples, hypermethylation of RAR-β was not detected and there was no significant association between age of diagnosis and hypermethylation of RAR-β in both types of gastric cancer. CONCLUSIONS These results support previous findings denoting a distinct profile of promoter hypermethylation status in the development of the intestinal and diffuse type of gastric carcinoma and the process of the tumorigenesis in these subtypes of gastric cancer is different from each other.

Abstract
A wide variety of genes have been associated with colorectal cancer (CRC) development and progression. The SMAD7 gene encodes an intracellular protein, which inhibits the transforming growth factor beta (TGF-β) signaling pathway, thereby having a key role in the control of neoplastic processes in various organs. The CHI3L1 gene encodes glycoprotein YKL-40, which plays a role in cell proliferation, anti-apoptosis, and angiogenesis. The present study aimed to evaluate the association of single nucleotide polymorphisms (SNPs) SMAD7 rs4939827 and CHI3L1 rs4950928, as well as circulating TGFβ-1 and YKL-40 levels with CRC in an Egyptian population of 77 CRC patients and 36 healthy controls. Polymorphisms in the SMAD7 rs4939827 and the CHI3L1 rs4950928 genes were determined using the real-time polymerase chain reaction (RT-PCR). Both the SMAD7 rs4939827 TT genotype and the CHI3L1 rs4950928 C allele were associated with the rectal but not the colon cancer. In addition, the C allele of both SMAD7 rs4939827 and CHI3L1 rs4950928 was associated with increased serum levels of TGF-β1 and YKL-40, respectively. In conclusion, our data suggest that SMAD7 rs4939827 and CHI3L1 rs4950928 SNPs have no significant association with CRC. A significant association of SNP in SMAD7 rs4939827 and CHI3L1 rs4950928 was revealed between the rectal cancer and colon cancer patients.

Abstract
Based on genome-wide association studies (GWAS) a linkage between several variants such as single nucleotide polymorphisms (SNPs) in intron 3 of SMAD7 (mothers against decapentaplegic homolog7) were, rs12953717, rs4464148 and rs4939827 has been noted for susceptibility to colorectal cancer (CRC). In this study we investigated the relationship of rs12953717 and rs4464148 with risk of CRC among 487 Iranian individuals based on a case- control study. Genotyping of SNPs was performed by PCR-RFLP and for confirming the outcomes, 10% of genotyping cases were sequenced with RFLP. Comparing the case and control group, we have found significant association between the rs4464148 SNP and lower risk of CRC. The AG genotype showed decreased risk with and odds ratio of 0.635 (adjusted OR=0.635, 95% CI: 0.417-0.967, p=0.034). There was no significant difference in the distribution of SMAD7 gene rs12953717 TT genotype between two groups of the population evaluated (adjusted OR=1.604, 95% CI: 0.978-2.633, p=0.061). On the other hand, rs12953717 T allele showed a statistically significant association with CRC risk (adjusted OR=1.339, 95% CI: 1.017-1.764, p=0.037). In conclusion, we found a significant association between CRC risk and the rs4464148 AG genotype. Furthermore, the rs12953717 T allele may act as a risk factor. This association may be caused by alternative splicing of pre mRNA. Although we observed a strong association with rs4464148 GG genotype in affected women, we did not detect the same association in CRC male patients.

Abstract
BACKGROUND Development of gastric cancer (GC) is a multistep process that requires alterations in the expression of oncogenes and tumor suppressor genes, occurring over several decades. The p53 tumor suppressor protein is involved in cell-cycle control, apoptosis and DNA repair. One of the most important regulators of p53 is MDM2, which acts as a negative regulator in the p53 pathway. Based on the key role of p53 and MDM2 in tumor suppression, polymorphisms that cause change in their function might affect cancer risk. We therefore elevated associations of the polymorphisms of p53 (R72P) and MDM2 (SNP309) with GC in Iran. MATERIALS AND METHODS A total of 104 patients with gastric cancer and 100 controls were recruited. Genomic DNA was extracted from fresh gastric samples. Genotyping of the p53 and MDM2 genes was performed using allele specific PCR (AS-PCR). RESULTS There was no significant difference between the p53 codon 72 polymorphism distribution in control and patient groups (p=0.54), but the G allele of MDM2 was found to be over-represented in patients (p=0. 01, Odds Ratio=2. 08, 95% Confidence Interval= 1.37-4.34). CONCLUSIONS The p53 R72P seems not to be a potential risk factor for development of GC among Iranian patients, but our data suggest that MDM2 SNP309 might modify the risk related to GC.

Abstract
BACKGROUND/AIMS The present study was aimed to investigate the correlation between selected clinicopathological characteristics and p53 protein overexpression, in Indian gastric cancer patients. METHODOLOGY Here, we studied specimens from 103 patients with gastric carcinomas and cases were categorized by AJCC-TNM classification. The p53 expression was analyzed in all the specimens by immunohistochemistry (IHC) and was correlated with the clinicopathological characteristics of the patients as well as etiological factors for gastric cancer. The cases were considered p53 overexpressed if more than 25% of the tumor cells were found to be expressing this protein. RESULTS We found significant association of p53 overexpression with the gender (p = 0.004) and histology grades (p = 0.001). However, p53 overexpression was not found to be significantly associated with other clinicopathological characteristics like age, cell differentiation, stage and location and various etiological factors. CONCLUSIONS Our observation showed that IHC-based detection of altered expression of p53 protein in gastric carcinomas may play an important role for diagnosing the progression of gastric carcinoma, even in the early stages.

Detection of TP53 R249 Mutation in Iranian Patients with Pancreatic Cancer. JOURNAL OF ONCOLOGY 2013; 2013:738915.

Abstract
The TP53 gene encodes tumor protein p53 which play a major role in the etiology of pancreatic cancer. The important role of codon 249 of TP53 for binding of p53 to its sequence-specific consensus site in DNA has been revealed by crystallography's studies, and mutation at this codon was detected in the plasma of some human cancers. The TP53 Mut assessor software within the International Agency for Research on Cancer (IARC) TP53 Database was performed to evaluate every possible mutation at codon 249. DNA was extracted from the plasma of 133 pancreatic cancer patients and 85 noncancer-bearing individuals. Exon 7 in TP53 was amplified, and mutation at R249 was identified by the endonuclease cleavage of HaeIII. The group of patients showed a frequency of 11% (22 of 133 samples) R249 mutation compared to 3.5% (3 of 85 samples) in the group of control which was significant (P = 0.03). This mutation demonstrated statistically significant association with pancreatic cancer risk in unadjusted odds ratio (OR: 3.74, 95% CI: 1.1–13.2; P = 0.041); however when adjusted for confounding factors, it was marginally significant because of lower control samples. These findings demonstrate that mutation at R249 of TP53 can be considered for increasing risk of pancreatic cancer that needs more research.
