Expression profile of messenger and micro RNAs related to the histaminergic system in patients with five subtypes of breast cancer.

Disparities in estrogen receptor (ER), progesterone receptor, human epidermal growth factor receptor 2 (HER2), and Ki67 proliferation indices facilitate the categorization of breast cancer into four principal subtypes: luminal A, luminal B, HER2-positive, and triple-negative breast cancer (TNBC). Preclinical studies investigating the therapeutic potential of histaminergic system targeting in breast cancer have shown promising results. This study aimed to assess the expression profiles of messenger ribonucleic acid (mRNA) and micro RNA (miRNA) related to the histaminergic system in five subtypes of breast cancer among Polish women.

Expression Profiles of Dopamine-Related Genes and miRNAs Regulating Their Expression in Breast Cancer.

This study aimed to assess the expression profile of messenger RNA (mRNA) and microRNA (miRNA) related to the dopaminergic system in five types of breast cancer in Polish women. Patients with five breast cancer subtypes were included in the study: luminal A ( = 130), luminal B ( = 196, including HER2-, = 100; HER2+, = 96), HER2+ ( = 36), and TNBC ( = 43); they underwent surgery, during which tumor tissue was removed along with a margin of healthy tissue (control material). The molecular analysis included a microarray profile of mRNAs and miRNAs associated with the dopaminergic system, a real-time polymerase chain reaction preceded by reverse transcription for selected genes, and determinations of their concentration using enzyme-linked immunosorbent assay (ELISA).

The influence of selected microRNAs on the expression profile of genes and proteins related to the tumor necrosis factor-alpha signaling pathways in endometrioid endometrial cancer.

Purpose: Tumor necrosis factor exerts many adverse biological effects, from cell proliferation to cell death. Accurate diagnosis and treatment are therefore difficult due to many factors influencing tumor necrosis factor-alpha (TNF-α) signaling, including microRNAs (miRNAs), especially in tumors. The aim of the study was to determine the influence of miRNAs on the expression profile of genes and proteins related to TNF-α signaling in endometrial cancer.

Detection and Genotyping of Human Papillomavirus (HPV16/18), Epstein-Barr Virus (EBV), and Human Cytomegalovirus (HCMV) in Endometrial Endometroid and Ovarian Cancers.

The purpose of this study was to evaluate the relationship between human papillomavirus (HPV16/18), Epstein-Barr virus (EBV), and human cytomegalovirus (HCMV) infections and the occurrence of ovarian cancer in 48 women, of whom 36 underwent surgery and chemotherapy (group A), 12 in whom surgery was sufficient (group B), and 60 with endometroid endometrial cancer stage G1-G3 (group C), compared to patients in whom the uterus and its appendages were removed for nononcological reasons (control group). The detection of HPV, EBV, and HCMV in tumor tissue and normal tissue was performed using the real-time polymerase chain reaction (RT-PCR) technique. A statistically significantly higher risk of endometrial cancer was noted in patients infected only with HCMV (OR > 1; < 0.

Endothelin-3 is epigenetically silenced in endometrioid endometrial cancer.

Purpose: Changes in the activity of endothelins and their receptors may promote neoplastic processes. They can be caused by epigenetic modifications and modulators, but little is known about endothelin-3 (EDN3), particularly in endometrial cancer. The aim of the study was to determine the expression profile of endothelin family and their interactions with miRNAs, and to assess the degree of EDN3 methylation.

The aim of this study was to determine the expression profile of the biogenic amine-related genes and proteins in endometrioid endometrial cancer compared to the control group.

Expression Pattern of Leptin and Its Receptors in Endometrioid Endometrial Cancer.

The identification of novel molecular markers and the development of cancer treatment strategies are very important as cancer incidence is still very high. Obesity can contribute to cancer progression, including endometrial cancer. Adipocytes secrete leptin, which, when at a high level, is associated with an increased risk of cancer.

Molecular Landscape of the Epithelial-Mesenchymal Transition in Endometrioid Endometrial Cancer.

Modern diagnostics are based on molecular analysis and have been focused on searching for new molecular markers to use in diagnostics. Included in this has been the search for the correlation between gene expression in tissue samples and liquid biological materials. The aim of this study was to evaluate the differences in the expression profile of messenger RNA (mRNA) and micro-RNA (miRNA) related to the epithelial-mesenchymal transition (EMT) in different grades of endometrial cancer (G1-G3), in order to select the most promising molecular markers.

Assessment of Dysfunction in the Urinary System as Well as Comfort in the Life of Women during and after Combination Therapy Due to Ovarian and Endometrial Cancer Based on the SWL, II-Q7 and UDI-6 Scales.

This work aimed to assess the influence of oncological combination therapy that was done on endometrial or ovarian cancer and how the urinary system is influenced as well as the quality of life in comparison to a group of female patients after the removal of the uterus with appendages due to endometrial cancer, which did not require the supplementation of therapy after operative treatment. The study included 87 patients with endometrial cancer, where, after the removal of the uterus, there was no need for conducting adjuvant therapy (C), as well as 92 female patients with endometrial cancer or 38 patients with ovarian cancer in whom combination therapy was conducted (group A, B). The assessment of the quality of life was conducted using the questionnaires: Satisfaction Life Scale (SWLS), Incontinence Impact Questionnaire, Short Form (IIQ-7), and Urogenital Distress Inventory (UDI-6) for three, six, nine, and 12 months after the conclusion of oncological treatment.

Pregnancy and Childbirth in the COVID-19 Era-The Course of Disease and Maternal-Fetal Transmission.

From the beginning of the Coronavirus Disease 2019 (COVID-19) pandemic, special attention has been paid to pregnant women and to monitoring comorbidities, such as gestational diabetes and hypertension, which could increase their risk of disease and death. The purpose of this review is to synthesize the available knowledge on the course of COVID-19 in pregnant women as well as the risk of maternal-fetal transmission. The study indicated that the course of COVID-19 is worse in pregnant women who are more often admitted to intensive care units or who require mechanical ventilation than nonpregnant women with COVID-19.

Evaluation of Variances in VEGF-A-D and VEGFR-1-3 Expression in the Ishikawa Endometrial Cancer Cell Line Treated with Salinomycin and Anti-Angiogenic/Lymphangiogenic Effect.

Background: In cancer, an excessive and uncontrolled process of creating new blood and lymphatic vessels that play a key role in the metastasis process can be observed. The Vascular Endothelial Growth Factor (VEGF-A,-B,-C,-D) family together with their specific receptors (VEGFR-1,-2,- 3) plays a key role in these processes, therefore, it would be reasonable to determine the correct pattern of their expression.

Objectives: The study aimed to assess the use of salinomycin as an anti-angiogenic and anti-lymphangiogenic drug during endometrial cancer by examining changes in the expression pattern of VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGFR-1, VEGFR-2 and VEGFR-3 depending on the treatment period of the Ishikawa endometrial cancer cells with salinomycin in comparison to the control culture.
