Synergistic effect of selenium and genipin triggers viability of 3T3 cells on PVA/Gelatin scaffolds.

Purpose: The aim of this study was to reveal the first time synergistic effect of GP and selenium (Se) on 3T3 cells seeded on natural and non-cytotoxic porous scaffolds with poly(vinyl alcohol) (PVA) and gelatin (GE).

Methods: Electrospinning scaffolds were produced as PVA/GE/GA crosslinked with glutaraldehyde (GA) and freeze/dried scaffolds crosslinked with genipin (GP) were divided into two groups as PVA/GE/GP5 and PVA/GE/GP8. The scaffolds were investigated in terms of pore morphology, swell ratio, biodegradation, and biocompatibility.

The effect of iron on the expression levels of calcium related gene in cisplatin resistant epithelial ovarian cancer cells.

Aim: Anticancer drugs (chemotherapeutics) used in cancer treatment (chemotherapy) lead to drug resistance. This study was conducted to investigate the possible effect of iron on calcium homeostasis in epithelial ovarian cancer cells (MDAH-2774) and cisplatin-resistant cells of the same cell line (MDAH-2774/DDP).

Methods: To develop MDAH-2774/DDP cells, MDAH-2774 (MDAH) cells were treated with cisplatin in dose increases of 5 μM between 0 μM and 70 μM.

Iron alters Ca homeostasis in doxorubicin-resistant K562 cells.

Iron is an essential trace element especially in cell proliferation, and growth for various cellular events. An increasing amount of research has shown that iron metabolism is altered in tumour cells which usually have rapid growth rates. However, the number of studies on iron metabolism, and calcium regulation are limited in drug-resistant tumour cells.

Calcium homeostasis in cisplatin resistant epithelial ovarian cancer.

Intracellular calcium concentration ([Ca2+]i) may have an important role in the development of chemoresistance, which is an essential problem in cancer chemotherapy. Cisplatin (DDP), which modulates the intracellular calcium concentration by different mechanisms, is an antineoplastic agent with high success rate in cancer therapies. We investigated the regulatory role of [Ca2+] in cisplatin resistance in epithelial ovarian cancer cell line, in MDAH-2774, and its chemoresistant subclone MDAH-2774/DDP.
