Distant metastasis and local recurrence are still the major causes for failure of treatment in patients with ovarian carcinoma (OC), making it urgent to further elicit the molecular mechanisms of OC metastasis. Sirtuin-3 (SIRT3), a member of the NAD(+)-dependent Class III histone deacetylases, may function as different role depending on the cell-type and tumor-type. However, the function and mechanism of SIRT3 has been not explored in OC metastasis. Here, we found that SIRT3 was significantly down-regulated in the metastatic tissues and highly metastatic cell line of ovarian cancer. In addition, knockdown of SIRT3 enhanced the migration and invasion in vitro and the liver metastasis in vivo of ovarian cancer cell. By contrast, ectopic overexpression of SIRT3 dramatically suppressed cancer cell metastatic capability. Mechanistically, SIRT3 inhibits epithelial-to-mesenchymal transition (EMT) by down-regulating Twist in ovarian cancer cells. Furthermore, an interaction between SIRT3 and Twist was detected. In conclusion, our results demonstrated that SIRT3 plays a crucial suppressive role in the metastasis of ovarian cancer by down-regulating Twist, and that this novel SIRT3/Twist axis may be valuable to develop new strategies for treating OC patients with metastasis.

Background: Extraskeletal osteosarcoma (ESOS) is a rare kind of sarcoma with a low preoperative diagnosis and a poor prognosis. ESOS arising from abdominal mesentery is extremely rare. Increasing diagnostic methods and standardizing treatment protocols are crucial issues of ESOS.

Background: Olaparib is a relatively new poly(ADP-ribose) polymerase inhibitor (PARPi) administered to ovarian cancer (OC) patients with a complete or partial response to first-line chemotherapy. One of the metabolic side effects of olaparib is the disruption of glucose homeostasis, often resulting in hyperglycemia The study was a retrospective analysis of olaparib-induced hyperglycemia in OC patients with initial normoglycemia following the first, second, and third month of olaparib treatment METHODS: The study involved 32 OC patients, classified into three groups according to their Body Mass Index (BMI): normal BMI (BMI 18.5-24.

Ovarian cancer presents a significant treatment challenge due to its insidious nature and high malignancy. As autophagy is a vital cellular process for maintaining homeostasis, targeting the autophagic pathway has emerged as an avenue for cancer therapy. In the present study, we identify apolipoprotein B100 (ApoB100), a key modulator of lipid metabolism, as a potential prognostic biomarker of ovarian cancer.

The distinctive characteristics of an individual's T cell receptor repertoire are crucial in recognizing and responding to a diverse array of antigens, contributing to immune specificity and adaptability. The repertoire, famously vast due to a series of cellular mechanisms, can be quantified using repertoire sequencing. In this study, we sampled the repertoire of 85 women: ovarian cancer patients (OC) and healthy donors (HD), generating a dataset of T cell clones and their abundance.

Objective: The presence of the microcystic elongated and fragmented (MELF) pattern, distinguished by its microcystic, elongated and fragmented attributes, constitutes a common manifestation of myometrial invasion (MI) within endometrial carcinoma. However, the prognostic significance of this pattern has not been definitively established. Consequently, this research aimed to clarify the prognostic implications of the MELF pattern for individuals diagnosed with endometrial carcinoma.
