male breast cancer is a rare disease with an increasing trend. due to limited information especially about the genetic basis of the disease in iran and the lower age of its onset, the disease requires more attention. the aim of this study was to screen the male patients with breast cancer for brca mutations as well as tissue markers of estrogen receptor (er), progesterone receptor (pr), human e...

We analyzed 563,099 common (minor allele frequency, MAF≥0.01) and rare (MAF < 0.01) genetic variants annotated in ExAC and UniProt and 26,884 disease-causing variants from ClinVar and UniProt occurring in the coding region of 17,975 human protein-coding genes. Three novel sets of genes were identified: those enriched in rare variants (n = 32 genes), in common variants (n = 282 genes), and in di...

background: proliferation and expansion of cancer stem cells as spheroids were proved in previous studies. but, capability of primary tumor-derived stem cells to keep their unique properties in vitro is still disputed. so, the goal of this study was to isolate, expand and characterize of colon cancer-derived stem cells. material and methods: in the present work, colon cancer stem cells markers ...

background: this study intends to determine the diagnostic and prognostic roles of hypermethylation of serum rassf1a and protocadherin-10 promoters in females with breast cancer. methods: this study enrolled 80 breast cancer patients and 80 apparently normal healthy controls. the promoter methylation status of serum rassf1a and pcdh10 genes was investigated using methylation specific pcr. resul...

Epigenetic inactivation of tumor-suppressor and other regulatory genes plays a critical role in carcinogenesis. Transcriptional silencing is often maintained by DNA methyl transferase (DNMT)-mediated hypermethylation of CpG islands in promoter DNA. Nucleoside analogs including azacytidine and decitabine have been used to inhibit DNMT and re-activate genes, and are clinically used. Their shortco...

Basal cell nevus syndrome (BCNS, OMIM 109400) is a familial cancer characterized by the development of numerous basal cancers and various other developmental abnormalities, including epidermal cysts skin, calcified dural folds, keratocysts jaw, palmar plantar pits, ovarian fibromas, medulloblastomas, lymphomesenteric cysts, fetal rhabdomyomas. BCNS shows autosomal dominant inheritance caused mu...

There is an increased global outbreak of diseases caused by coronaviruses affecting respiratory tracts birds and mammals. Recent dangerous are MERS-CoV, SARS-CoV, SARS-CoV-2, causing illness even failure several organs. However, profound impact coronavirus on host cells remains elusive. In this study, we analyzed transcriptome SARS-CoV-2 infected human lung-derived cells, observed that infectio...

Background In kindreds carrying path_BRCA1/2 variants, some women in these families will develop cancer despite testing negative for the family's pathogenic variant. These families may have additional genetic variants, which not only may increase the susceptibility of the families' path_BRCA1/2, but also be capable of causing cancer in the absence of the path_BRCA1/2 variants. We aimed to ident...
