background: the aberrant expression of dickkopf-1 (dkk1), triose phosphate isomerase (tpi) and fatty acid binding-protein 5 (fabp5) in lung cancer tissues and their presence in secretome of lung cancer cell lines were reported. here, serum levels of these molecules in lung cancer patients were compared to those in a healthy control group. materials and methods: the patients’ group consisted of ...
abstract background: esophageal cancer is one of the major malignancies, with various epidemiological aspects in recent years in developing countries, including increased prevalence and variations of pathologic patterns. this may be due to increasing rates of barrett’s esophagus, gastroesophageal reflux, smoking and obesity. this study was performed from 1991 to 2005 in order to evaluate variou...
background and aim: squamous cell carcinoma is the eighth common cancer and forms 94% of oral malignancies. nowadays, many molecular and genetic changes have been known to affect tumoral behavior which might be good for drug production and gene therapy. it has been known that mutated p53, overexpression of p63 as an oncogene and hpv infection are correlated with clinicopathological behavior of ...
telomerase activation is one of the main pathways to immortalize cancer cells. in many kinds of cancer cells, this special reverse transcriptase stabilizes and elongates telomeres and prevents telomere erosion that naturally occurs in every cell division. esophageal cancer is the fifth most frequent cause of cancer death worldwide, and is highly associated with alcohol, smoking, cultural habits...
background: cutaneous malignancies are common in dermatologic practice. due to their relation to sun exposure the characteristics of these malignancies can differ in various geographic locations. this study intends to determine the characteristics of surgically treated cutaneous malignancies and various surgical modalities that have been applied. methods: this was a retrospective study of patie...
Connective tissue diseases, including scleroderma, may be associated with an increased risk of lung cancer. The most common type of lung cancer associated with systemic sclerosis is adenocarcinoma or bronchoalveolar carcinoma, and small cell carcinoma is rare. This reports presents a 54-year-old non-smoker woman with a history of scleroderma who was examined due to aggravation of shortness of ...
slug (snai2), a regulator of epithelial-to-mesenchymal transition (emt), is a zinc finger transcription factor involved in neurulation. intriguingly, snai2 gene expression has been linked to the aggressiveness of neuroblastoma, melanoma and lung, colon, ovarian and breast carcinoma. of note, many metastatic cancers recapitulate emt to enhance cell motility and invasion. moreover, metastasis is ...
back ground: the aim of this study was to characterize the immunohistochemical expression of galectin 1, 3, and 9 in normal oral epithelium, oral squamous papilloma, and oral squamous cell carcinoma. materials and methods: immunohistochemical staining for galectins 1, 3, and 9 was evaluated in 8 samples of normal oral squamous epithelium, 15 samples of oral squamous papilloma, and 41 samples of...
results there were 39 cases with lymph node metastasis in 59 malignant tumors, and 0 cases in 6 benign follicular type tumors. the staining scores by jt-95 of the 39 tumors with lymph node metastasis were 5+ in eight cases and 6+ in 31 cases. on the other hand, the scores of 20 malignant tumors without lymph node metastasis were < 4+ in all of the cases. in the co-cultured assay, numerous adhes...
Thyroid gland metastatic tumors are rare in clinical practice. Clear cell RCC is one of common metastatic tumors to thyroid. We here reported a case of incidentally found clear cell renal carcinoma metastasis to the thyroid gland 3 years after nephrectomy, in the thyroidectomy procedure performed for the patient due to the thyroid enlargement caused by multinodular goiter. A 65-year-old Iranian...
