OBJECTIVES To determine the frequency of primary circulating prostate cells in men with prostate cancer at the time of diagnosis, the association with micrometastasis, sub-classification for CD82 and the relation with pathological stage. To determine their clinical usefulness to identify patients in whom radical prostatectomy would be first choice therapy. METHODS Men with the diagnosis of pr...
Background: Colorectal carcinoma (CRC) is one of the most common human cancers. It fourth cause death from cancer. cancer third in men and second women worldwide. Objective: To evaluate immunohistochemical expression KAI-1/CD82 different stages colorectal to biological behavior tumor target therapy. Patients Methods: Thirty formalin-fixed, paraffin-embedded tissue (obtained archive Al-Azhar Uni...
Metastasis-suppressing gene product CD82 and its analogue CD9 are considered to suppress the malignancy of various human cancers, although the rationale for this effect is unknown. The present study addresses phenotypic changes in Chinese hamster ovary mutant cell line ldlD deficient in UDP-Glc 4-epimerase and expressing CD82 or CD9 by cDNA transfection. Only CD82or CD9-expressing cells grown i...
زمینه و هدف: مطالعات نشان دادهاند استروئیدهای جنسی بر تکثیر سلولهای سرطانی در سطح سلولی و مولکولی تأثیرگذارند. در این مطالعه به بررسی اثر غلظت سیتوتوکسیک تستوسترون بر بیان ژنهای Bax، Bcl-2 و KAI-1/CD82 در سلولهای آدنوکارسینومای کولورکتال (HT29) و گلایوبلاستومای مغزی (A172) پرداخته شد. روش بررسی: در این مطالعه تجربی - آزمایشگاهی، سلولهای HT29 و A172 به گروههای شاهد و گروههای تحت تأثیر غلظ...
We analyzed herein whether members of the tetraspanin superfamily are involved in human immature dendritic cell (DC) functions such as foreign antigen internalization, phagocytosis, and cell migration. We show that CD63, CD9, CD81, CD82, and CD151 are present in immature DCs. Whereas CD9 and CD81 are mostly expressed at the cell surface, CD63 and CD82 are also located in intracellular organelle...

BACKGROUND The aim of this study was to clarify the clinical significance of TM4SF members CD9, CD63 and CD82 in human gastric carcinoma. METHODS By employing RT-PCR and immunohistochemistry, we studied the expression of CD9, CD63 and CD82 in 49 paired tissue specimens of normal gastric mucosa and carcinoma. All tissues were obtained from patients who underwent curative surgery. RESULTS All...
Four-transmembrane-domain proteins of the tetraspanin superfamily are the organizers of specific microdomains at the membrane [TERMs (tetraspanin-enriched microdomains)] that incorporate various transmembrane receptors and modulate their activities. The structural aspects of the organization of TERM are poorly understood. In the present study, we investigated the role of gangliosides in the ass...
BACKGROUND Breast cancer is the leading cause of cancer death in females worldwide, and the majority type is infiltrating ductal carcinoma (IDC). Most of IDC patients died of metastasis and recurrence. Cancer stem cells (CSCs) are defined with the ability to be self-renewal and potentially promote proliferation and formation of tumors. CSCs are related to angiogenesis and are important targets ...
هدف: سرطان پروستات یکی از شایعترین سرطانها در کشورهای پیشرفته است. در بیشتر موارد مرگ و میر ناشی از سرطان به خاطر پیشرفت متاستازی است، از اینرو جلوگیری از فرآیند متاستازی ضرورت دارد. سیلیبینین نوعی ترکیب فلاوونوئیدی است که تکثیر سلولی را مهار میکند و سبب مرگ سلولهای سرطان پروستات انسانی میشود. در این مطالعه بیان ژن cd82 در سلولهای pc-3 تیمار شده با غلظتهای افزایشی سیلیبینین ارزیابی شد ک...
