Serum contains many growth factors and nutrients that stimulate colony formation of hematopoietic progenitor cells (HPC) in semisolid cultures. In the absence of serum, no proliferation of HPCs could be obtained in semisolid medium cultures of partially purified bone marrow cells in the presence of multiple hematopoietic growth factors, insulin, cholesterol, and purified clinical-grade human al...
there exists an association between pi3k pathway licentious activity and the considerable feature of high metastatic potential of the genitourinary cancer cells. although du 145 and 5637 have functional phosphatase and tensin homolog (pten) tumor suppressor gene, which antagonizes pi3k function, pc-3 is null for pten gene. in pursuit to explain why pten bearing cell lines display high metastati...
ownload previously reported that angiotensin II type 1 receptor (AT1R) antagonists enhanced the cytotoxity of hlorodiammineplatinum (CDDP) in a bladder cancer xenograft model. To elucidate the synergistic nism, we investigated whether reactive oxygen species (ROS) generation induced by CDDP may affect ulation of AT1R expression. Five invasive human bladder cancer cell lines, T24, UMUC-3, 5637, ...
The multipotent hemopoietic stem cell has fastidious growth requirements in vitro. Traditionally, phytohemagglutinin-stimulated leukocyte conditioned medium has been used to supply the undefined growth factors required for culture of the human multipotent hemopoietic progenitor. We describe the use of medium conditioned by the bladder carcinoma cell line, 5637, to replace PHA-LCM in CFU-GEMM cu...
سرطان مثانه چهارمین سرطان شایع در مردان و نهمین سرطان رایج در زنان جهان به شمار می رود. رایج ترین نوع سرطان مثانه کارسینومای سلول های ترانزیشنال (tcc) است. شیمی درمانی از جمله روش های رایج برای مهار و یا کاهش سرعت رشد سلول های سرطانی به شمار می رود. اما از آن جا که دارو های شیمی درمانی علاوه بر سلول های سرطانی، اغلب سبب تخریب سلول های سالم نیز می شوند و همچنین به دلیل ایجاد مقاومت دارویی در مرا...
Cisplatin (CDDP)-based combination chemotherapy remains the mainstream treatment for advanced bladder cancer. However, its efficacy is often limited due to the development of resistance for which underlying mechanisms are poorly understood. Meanwhile, emerging evidence has indicated the involvement of androgen-mediated androgen receptor (AR) signals in bladder cancer progression. In this study,...
Bladder cancer, a common urinary tract tumor, has high mortality and recurrence rates associated with metastasis. Aminopeptidase N (APN) expression and metastasis have been indicated to be associated with one another. Ubenimex may function as an APN inhibitor to inhibit the degradation of the extracellular matrix during tumorigenesis. Furthermore, APN has been widely used as an adjuvant therapy...
We report herein the development, functional and molecular characterization of an isogenic, paired bladder cancer cell culture model system for studying platinum drug resistance. The 5637 human bladder cancer cell line was cultured over ten months with stepwise increases in oxaliplatin concentration to generate a drug resistant 5637R sub cell line. The MTT assay was used to measure the cytotoxi...
Androgen receptor (AR) signals play important roles in bladder carcinogenesis and tumor progression. Activation of the epidermal growth factor receptor (EGFR) family, including EGFR and ERBB2, leads to bladder cancer cell growth and correlates with poor patients' prognosis. However, cross talk between AR and EGFR/ERBB2 pathways in bladder cancer remains poorly understood. In AR-positive bladder...
objective: the anti-cancer properties of curcumin, a poliphenol extract from the rhizome of curry, has been confirmed by many investigators. however, low levels of uptake, tissue distribution and rapid metabolism has limited its application as an anti-cancer drug. this study is aimed at increasing curcumin's water solubility due to a biodegradable, neutral and non-toxic micellar nano-carrier ca...
