Homeobox C8 (HOXC8) is a transcription factor that has been reported as a potential driver oncogene in several tumors and involved in the regulation of many cancer-related proteins. In this study, we investigated the expression and role of HOXC8 in ovarian cancer. Western blot and immunohistochemistry analyses were performed to detect the expression of HOXC8. Kaplan-Meier curve showed that high expression of HOXC8 was related to poor prognosis of patients with epithelial ovarian cancer (EOC). Starvation and refeeding assay were used to assess cell cycle, suggesting that HOXC8 played a critical role in EOC cell proliferation. HOXC8 depletion by small interfering RNA inhibited cell proliferation, migration, and induced apoptosis in EOC cells. Moreover, HOXC8 knockdown increased the expression of ZAC1. Owing to the overexpression of HOXC8, our findings implied that HOXC8 is involved in the progression of EOC and could be a potential therapeutical approach of EOC.

Genetic alterations to serine-threonine kinase 11 () have been implicated in Peutz-Jeghers syndrome and tumorigenesis. Further exploration of the context-specific roles of liver kinase B1 (LKB1; encoded by ) observed that it regulates AMP-activated protein kinase (AMPK) and AMPK-related kinases. Given that both migration and proliferation are enhanced with the loss of LKB1 activity combined with the prevalence of genetic alterations in cancer biopsies, LKB1 was marked as a tumor suppressor.

Ovarian squamous cell carcinoma (SCC) is a rare entity among primary ovarian cancers. This type of cancer typically originates from the transformation of mature cystic teratomas, commonly known as dermoid cysts, and occasionally from associations with endometriosis or Brenner's tumors. The typical clinical scenario involves presentation in postmenopausal women, with symptoms arising from tumor growth or metastasis.

Background Ovarian cancer is the third most prevalent form of cancer among women in India. The majority of patients are diagnosed at an advanced stage. Many women with late-stage ovarian cancer experience a recurrence and need subsequent treatment, even after initial therapy.

Lotus seeds, also known as Nelumbinis semen, has been utilized for over 7,000 years as vegetable, functional food and medicine. In this study, we primarily investigated the anticancer effects of lotus seed extracts, particularly of the methanolic extract (MELS) on cell proliferation inhibition, apoptosis induction and cell cycle arrest in ovarian cancer cell lines. Further, we studied the phytochemical composition of the MELS by gas chromatography-mass spectrometry (GC-MS) analysis.
