The recent investigation on PARK-2, a putative tumor suppressor gene, has found that it has been altered in multiple human malignancies. However, the clinical impact of PARK-2 alteration in uterine cervix carcinoma has not yet been studied. Therefore, we aimed to examine mutations, promoter hypermethylation, and protein expression of PARK-2 among the North Indian patients and their association with clinical parameters to evaluate the implication of PARK-2 in the genesis of cervical cancer. A total of 168 patient samples were processed for mutational analysis by single-strand conformation polymorphism, sequencing, and further in silico analysis of the identified mutations...

Background. The body's cell behaviour is controlled by various signalling pathways, one of which is NOTCH. It has been found that a partial loss of the NOTCH function or abnormal strengthening of NOTCH signalling are related to various human diseases and developmental disorders. Materials and methods. PubMed was the main source of information for this paper. Results. The paper overviews the association between oncologic diseases and the participants of the NOTCH signalling pathway. In cancerogenesis, the NOTCH signalling pathway can act as a tumour suppressor or an oncogene...

OBJECTIVE: Uterine sarcomas (US) and carcinosarcomas (CS) are rare, aggressive cancers. The lack of reliable preclinical models hampers the search for new treatment strategies and predictive biomarkers. To this end, we established and characterized US and CS patient-derived xenograft (PDX) models. METHODS: Tumor fragments of US and CS were subcutaneously implanted into immunocompromised mice. Engrafted xenograft and original tumors were compared by means of histology, immunohistochemistry, whole-genome low-coverage sequencing for copy number variations, and RNA sequencing...

Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine...

Preclinical Research To investigate the antiestrogenic activity of triptolide in human breast cancer cell line MCF-7 and immature female C57BL/6 mouse. The effects of triptolide on cell proliferation, cell cycle, and the expression of estrogen receptor alpha (ERα) and progesterone receptor (PR) were examined in MCF-7 cells. In vivo antiestrogenic effects of triptolide were observed after cotreatment of mice with E2 and triptolide for 4 days. Triptolide dose- and time-dependently inhibited cell growth in untreated or E2 -treated MCF-7 cells, which was associated with increased S phase arrest...

Mi Jung Kwon, So Young Kang, Eun Sook Nam, Seong Jin Cho, Young-Soo Rho
Tonsillar squamous cell carcinomas (TSCCs) are the most common human papillomavirus- (HPV-) associated oropharyngeal cancers with poor prognosis. Homeodomain-interacting protein kinase 2 (HIPK2) is a central regulator of p53, which participates in apoptosis during the DNA damage response. HIPK2 is involved in HPV-associated uterine cervical and cutaneous carcinogenesis through its binding of HPV E6, thereby preventing apoptosis and contributing to tumor progression. However, its clinical and prognostic significance in TSCC remains unclear...

BACKGROUND: Hysteroscopy, despite being the undisputed gold standard for the examination of the uterine cavity, is controversial as a routine procedure in infertile women. However, benign intrauterine conditions are common in women suffering repeated in vitro fertilization (IVF) failure, and growing evidence suggests a unique diagnostic and therapeutic role for hysteroscopy. Endometrial malignancy, on the contrary, is unreported by large published series of women with repeated IVF failures undergoing hysteroscopy, and its impact on fertility, for obvious reasons, has not been studied...

ETHNOPHARMACOLOGICAL RELEVANCE: Milicia excelsa (Welw.) C.C. Berg (Moraceae) is a medicinal plant recommended over tropical Africa as a cure for several ailments including amenorrhea. This is the hallmark of an ovarian lesion or a dysfunction of the hypothalamic-pituitary-ovarian axis which may lead to infertility, osteoporosis or endometrial cancer. However, regardless these traditional claims, no scientific report dealing with emmenagogue properties has been reported yet. AIM OF THE STUDY: To bring scientific evidence to the curative action of the plant, we proposed evaluating the effects of a root aqueous extract of Milicia excelsa on female Wistar rat sexual maturation...
