Antioxidative effect of dietary flavonoid isoquercitrin on human ovarian granulosa cells HGL5 in vitro.

This study aimed to examine the effect of dietary flavonoid isoquercitrin on ovarian granulosa cells using the immortalized human cell line HGL5. Cell viability, survival, apoptosis, release of steroid hormones 17beta-estradiol and progesterone, and human transforming growth factor-beta2 (TGF-beta2) and TGF-beta2 receptor as well as intracellular reactive oxygen species (ROS) generation were investigated after isoquercitrin treatment at the concentration range of 5-100 microg.ml-1.

response of human ovarian cancer cells to dietary bioflavonoid isoquercitrin.

Isoquercitrin is a dietary bioflavonoid used as a food supplement. We studied the mechanism underlying its effect in human ovarian cancer cells using OVCAR-3 cell line. Viability, survival, apoptosis, release of human transforming growth factor-β1 (TGF-β1) and TGF-β1 receptor, and intracellular reactive oxygen species (ROS) generation by OVCAR-3 cells were examined after isoquercitrin treatment at concentrations 5, 10, 25, 50, and 100 μg mL.

Detection of circulating tumor cells in metastatic breast cancer patients.

Objective: The objective of this study was the detection of circulating tumor cells (CTCs) in metastatic breast cancer patients.

Methods: Since only small numbers of circulating tumor cells (CTCs) are found in peripheral blood, at first we performed immunomagnetic separation as a concentration method suitable for selecting circulating tumor cells in peripheral blood. This was followed by analysis of isolated cells with the aid of laser scanning cytometry (LSC).

Circulating tumour cells in breast cancer--review.

Disseminated malignancies are responsible for the majority of cancer-related deaths. During the metastatic process, circulating tumour cells (CTCs) are generated. The presence of CTCs, epithelial cells found in the peripheral blood, is an essential step in establishing distant metastases.

Immunity profile in breast cancer patients.

Objectives: Despite the multifactorial pathogenesis of malignant transformation, it is assumed that deficiency in some immune mechanisms plays a considerable role in its development.

Background: Chronically activated immune cells exert tumour-promoting effects directly by influencing the proliferation and survival of neoplastic cells, as well as by indirect modulation of neoplastic microenvironments in favour of tumour progression.

Patients And Methods: We refer to results of two separate investigations that aim to monitor the immune functions in patients with breast cancer.
