shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...
Background and objectives: ZatariamultifloraBioss. (ZM) has shown several effects in gastrointestinal, respiratory and nervous system. In this study, the effect of Z. multiflora was examined in colon cancer cell lines of Caco-2. Methods: Total extract and petroleum ether, chloroform and methanol fractions of the plant were prepared us...
background and objective: cutaneous cytology is the study of scraping or smears obtained from skin lesions. although not commonly employed, cutaneous cytology has been a useful tool for clinicians due to simplified procedures and high sensitivity and specificity of presurgical clinical diagnosis of common types of skin tumors. this investigation was conducted to study usefulness of cutaneous cy...
زمینه و هدف: ساخت و ترکیب داروهای جدید گیاهی و شیمیایی علیه بیماری هایی مثل سرطان، از جمله تلاش های مهم سال های اخیر محسوب می شود. ترکیبات ترپنی از جمله ترکیبات مهمی هستند که خواص بیولوژیکی و فارماکولوژیکی متعددی دارند، اما به دلیل حلالیت کم آن ها در محلول های آبی کمتر مورد توجه بوده اند. سیکلودکسترین ها نیز نانوکپسول های طبیعی تشکیل شده از واحدهای گلوکزی هستند که می توانند ایجاد نانوحفره نماین...
Protein tyrosine phosphatase PRL-3 mRNA was found highly expressed in colon cancer endothelium and metastases. We sought to associate a function with PRL-3 expression in both endothelial cells and malignant cells using in vitro models. PRL-3 mRNA levels were determined in several normal human endothelial cells exposed or unexposed to the phorbol ester phorbol 12-myristate 13-acetate (PMA) and i...
The neuropeptide bombesin and its mammalian homologue, gastrin-releasing peptide (GRP), enhance proliferation in some but not all human tumor cell lines. The pathophysiological relevance of the bombesin/GRP receptor (GRP-R), which is expressed in 30% of human colon tumor cell lines and in 24-40% of native tumors, has not been clearly assessed at this time. We studied the effects of bombesin in ...
intraosseous squamous cell carcinoma is a rare type of squamous cell carcinoma that requires accurate and early diagnose which is important due to its invasive feature. this article presents a rare case report on intraosseous carcinoma in a 33-year-old patient. the case was a 33-year-old man who was referred to oral disease department of babol college of dentistry complaining of chin pain. in t...
The serological analysis of recombinant cDNA expression libraries (SEREX) by utilizing a library derived from a human pancreatic adenocarcinoma cell line and IgG antibodies from an allogeneic patient serum led to the identification of 18 genes: 13 of these were known genes, and 5 were unknown genes. In Northern and RT-PCR analyses, we found that the expression of mRNA of 14 genes was elevated i...
2-Chloroethyl (methylsulfonyl)methanesulfonate (ClEtSoSo) was more toxic to the BE (Mer-) cell line than to the HT-29 (Mer+) colon carcinoma. The sensitivity of the BE cells closely paralleled the induction of DNA interstrand cross-links by ClEtSoSo. No DNA interstrand crosslink formation was detected in the HT-29 cells after exposure to ClEtSoSo. Pretreatment of the HT-29 cells with methylatin...
