Effects of Curcumin and Its Analogue Desmethoxycurcumin on miR-133b and Its Target Gene GSTP-1 in Cisplatin-resistant Ovarian Cancer Cells.

Background/aim: Ovarian cancer, despite being the fifth most common gynecological malignancy, has the highest mortality rate. Recent clinical studies have explored the potential of natural products, like curcumin (CUR), to enhance conventional chemotherapy by targeting multiple cellular pathways. This study aimed to evaluate the effects of CUR and its analog, demethoxycurcumin (DMC), on human ovarian cancer and cisplatin-resistant ovarian cancer cell proliferation and apoptosis.

Evaluation of the genotoxicity, cytotoxicity, and bioactivity of calcium silicate-based cements.

Background: As calcium silicate-based cements (CSCs) have found success in various vital pulp therapy applications, several new CSC products have emerged. This study aimed to assess the genotoxicity, cytotoxicity, and bioactivity of four CSCs by comparing the newly introduced materials Bio MTA+ and MTA Cem with previously studied materials, Biodentine and NeoMTA.

Methods: Genotoxicity was evaluated using the micronucleus (MN) assay in human peripheral blood lymphocyte cells, measuring MN frequency and nuclear division index (NDI).

Antiproliferative effects of Turkish pomegranate (Punica granatum L.) extracts on MCF-7 human breast cancer cell lines with focus on antioxidant potential and bioactive compounds analyzed by LC-MS/MS.

In this study, eight different pomegranate (Punica granatum L.) cultivars from Turkey were evaluated for their antioxidant and cytotoxic effects on the MCF-7 breast cancer cell lines and MCF-10A breast fibrocystic epithelial cell lines with a focus on their chemical compositions by LC-MS/MS. Cell lines were treated with pomegranate juice extracts in different doses at selected time intervals (24th, 48th, and 72nd hour).

Different propolis samples, phenolic content, and breast cancer cell lines: Variable cytotoxicity ranging from ineffective to potent.

Researchers have started focusing on investigating the anticarcinogenic effects of natural products with the slightest side effects possible, because current breast cancer treatment approaches are unable to achieve absolute success especially on aggressive subtypes. Propolis is among these products with its antimicrobial, antifungal, anti-inflammatory, and anticancer effects. Therefore, seven different samples were collected from different regions (Argentina, China, and Istanbul-Turkey) and applied on nonaggressive breast cancer cell line (BCCL) MCF-7 and aggressive cell lines SK-BR-3, and MDA-MB-231.

Anatolian honey is not only sweet but can also protect from breast cancer: Elixir for women from artemis to present.

Natural products with bioactive components are widely studied on various cancer cell lines for their possible cytotoxic effects, recently. Among these products, honey stands out as a valuable bee product containing many active phenolic compounds and flavonoids. Numerous types of multifloral honey and honeydew honey are produced in Turkey owing to its abundant vegetation.

Combined effects of collagen type I alpha1 (COL1A1) Sp1 polymorphism and osteoporosis risk factors on bone mineral density in Turkish postmenopausal women.

Identification of risk factors for osteoporosis has been essential for understanding the development of osteoporosis. The collagen type I alpha1 (COL1A1) gene is suggested to be implicated in reduced bone mineral density (BMD) in osteoporosis. In the present study, the investigation of the effects of Sp1 polymorphic variants of COL1A1 gene on BMD values, and the determination of the association between COL1A1 Sp1 gene variants and osteoporosis risk factors in the context of gene-environment interaction in Turkish postmenopausal women were aimed.

Association between PTEN IVS4 polymorphism and development of colorectal cancer in a Turkish population.

Background: Phosphatase and tensin homolog (PTEN) is one of the most frequently mutated suppressor genes in human cancers. However, there are no data about the role of PTEN IVS4 polymorphism in development of colorectal cancer (CRC). The authors aimed to determine the role of PTEN IVS4 variants in the etiology of CRC.

Evaluation of ERα and VDR gene polymorphisms in relation to bone mineral density in Turkish postmenopausal women.

It has been suggested that the estrogen receptor alpha (ERα) and vitamin D receptor (VDR) genes as possibly implicated in reduced bone mineral density (BMD) in osteoporosis. The present study investigated the relation of ERα PvuII/XbaI polymorphisms and VDR FokI/TaqI polymorphisms with BMD in Turkish postmenopausal women. Eighty-one osteoporotic and 122 osteopenic postmenopausal women were recruited.
