Multifaceted Evaluation of Inhibitors of Anti-Apoptotic Proteins in Head and Neck Cancer: Insights from In Vitro, In Vivo, and Clinical Studies (Review).

This paper presents a multifaceted assessment of inhibitors of anti-apoptotic proteins (IAPs) in the context of head and neck squamous cell carcinoma (HNSCC). The article discusses the results of in vitro, in vivo, and clinical studies, highlighting the significance of IAPs in the resistance of cancer cells to apoptosis, which is a key factor hindering effective treatment. The main apoptosis pathways, including the intrinsic and extrinsic pathways, and the role of IAPs in their regulation, are presented.

The role of selected cytokines from the interleukin-1 family in the peritoneal fluid of women with endometriosis.

Objectives: Endometriosis is a complex, chronic inflammatory disease in which immune system disorders play an important role. Soluble mediators of the immune and inflammatory response, including cytokines, are involved in these processes. Therefore, the aim of the conducted research was to understand the role of selected cytokines belonging to the Interleukin-1(IL-1) family, including IL-36α, IL-36β, IL-36γ, IL-36R, IL-37 and IL-38, in the onset and development of endometriosis by analysing the concentration of the tested molecules and to determine whether their concentration depends on the stage of the disease.

Selected Flavonols Targeting Cell Death Pathways in Cancer Therapy: The Latest Achievements in Research on Apoptosis, Autophagy, Necroptosis, Pyroptosis, Ferroptosis, and Cuproptosis.

The complex and multi-stage processes of carcinogenesis are accompanied by a number of phenomena related to the potential involvement of various chemopreventive factors, which include, among others, compounds of natural origin such as flavonols. The use of flavonols is not only promising but also a recognized strategy for cancer treatment. The chemopreventive impact of flavonols on cancer arises from their ability to act as antioxidants, impede proliferation, promote cell death, inhibit angiogenesis, and regulate the immune system through involvement in diverse forms of cellular death.

Selected Flavonols in Breast and Gynecological Cancer: A Systematic Review.

The consumption of foods that are rich in phenolic compounds has chemopreventive effects on many cancers, including breast cancer, ovarian cancer, and endometrial cancer. A wide spectrum of their health-promoting properties such as antioxidant, anti-inflammatory, and anticancer activities, has been demonstrated. This paper analyzes the mechanisms of the anticancer action of selected common flavonols, including kemferol, myricetin, quercetin, fisetin, galangin, isorhamnetin, and morin, in preclinical studies, with particular emphasis on in vitro studies in gynecological cancers and breast cancer.

Cancer stem cells markers in ovarian cancer: Clinical and therapeutic significance (Review).

Ovarian cancer is a gynecological neoplasm that can be found in women, which, due to diagnostic difficulties, is often detected at advanced stages when treatment becomes a significant problem. Moreover, in a number of cases there is a cancer recurrence and resistance to standard chemotherapy treatment. It has been suggested that cancer stem cells (CSCs) that were not eradicated during therapy may be responsible for this.

Analysis of the concentration of CXCL8 chemokine and its CXCR1 and CXCR2 receptors in peritoneal fluid of women with endometriosis.

Unlabelled: Endometriosis is an inflammatory estrogen-dependent gynecological disease characterized by the presence of endometrial tissue outside the uterine cavity. An important role in the pathogenesis of this disease is played by disorders of the immune system involving chemokines and their receptors, including the CXCL8-CXCR1/ 2 system.

Aim: The aim of the study was to assess the concentration of the CXCL8 chemokine and its CXCR1 and CXCR2 receptors in the peritoneal fluid of women with endometriosis.

Analysis of CXCL8 and its receptors CXCR1/CXCR2 at the mRNA level in neoplastic tissue, as well as in serum and peritoneal fluid in patients with ovarian cance.

Understanding the relationship between the coexistence of inflammatory and neoplastic processes in ovarian cancer, particularly those involving chemokines and their receptors, may help to elucidate the involvement of the studied parameters in tumor pathogenesis and could lead to improved clinical applications. Therefore, the present study aimed to analyze the levels of C‑X‑C motif chemokine ligand 8 (CXCL8), and its receptors C‑X‑C chemokine receptor (CXCR)1 and CXCR2, in the serum and peritoneal fluid of women with ovarian cancer, and to evaluate the association between the expression of these parameters in tumor tissue and patient characteristics, particularly the degree of histological differentiation. The study group included women with ovarian cancer diagnosed with serous cystadenocarcinoma International Federation of Gynecology and Obstetrics stage IIIc and a control group, which consisted of women who were diagnosed with a benign lesion (serous cystadenoma).

The role of galectins‑1, 3, 7, 8 and 9 as potential diagnostic and therapeutic markers in ovarian cancer (Review).

The incidence of ovarian cancer is increasing, particularly throughout the highly developed countries, while this cancer type remains a major diagnostic and therapeutic challenge. The currently poorly recognized lectins called galectins have various roles in interactions occurring in the tumor microenvironment. Galectins are involved in tumor‑associated processes, including the promotion of growth, adhesion, angiogenesis and survival of tumor cells.

Participation of Selected Soluble BMP-2 and BMP-7 Bone Morphogenetic Proteins and Their Soluble Type I ALK-1 and Type II BMPR2 Receptors in Formation and Development of Endometriosis.

Angiogenesis is considered to be one of the key stages in the development of endometriosis. Recent studies indicate that bone morphogenetic proteins (BMPs) and their receptors (BMPR) may play an important role in the angiogenesis process. In the literature, however, there is a lack of publications concerning binding BMPs and their receptors with the pathogenesis of endometriosis.

The presence of anti-leucocyte antibodies in the plasma of convalescent women after SARS-CoV-2 infection as a reason for disqualification for plasma therapy - analysis based on a literature review.

According to the data from November 29 2020, the SARS-CoV-2 coronavirus was responsible for 61 866 635 cases of infections and 1 448 990 deaths worldwide, and the number is still growing rapidly. The main problem is the rapid increase in the number of patients with pneumonia complicated by respiratory failure. In the treatment of COVID- 19 patients, a significant effect of convalescent plasma (CP) therapy from convalescent patients with SARS-CoV-2 IgG neutralizing antibodies is indicated.
