Endometriosis is an inflammatory condition defined by the presence of endometrial glands and stroma outside the uterine cavity. Given the substantial body of evidence supporting the role of inflammation in the pathophysiology of various chronic illnesses, the concept of an anti-inflammatory diet has garnered significant attention in recent research. Some nutrients, such as omega-3 fatty acids and resveratrol (RES), have demonstrated distinct anti-inflammatory properties. Therefore, the objective of this systematic review was to search the Embase, Medline, and PubMed databases for literature from August 2008 to August 2023 regarding the effects of two anti-inflammatory dietary components, omega-3 and RES, on endometriosis. A total of 215 records were identified, out of which 58 were screened, 23 met the eligibility criteria, and 19 were included in this review. The results of this systematic review indicate that EPA is suggested to have anti-inflammatory properties and may serve as a potential marker for illness severity. RES offers a range of advantages, including inflammation reduction, angiogenesis suppression, proliferation inhibition, and apoptosis induction. To validate these findings and assess their clinical relevance, future research and clinical trials are warranted. [ABSTRACT FROM AUTHOR]

Endometriosis is defined as the presence of endometrial tissue outside of the uterine cavity. It is a chronic disease affecting approximately 10% of women. In addition to producing a vast array of symptoms, including chronic pelvic pain and dysmenorrhea, the condition significantly impacts quality of life. Over the past century, several theories have attempted to explain the pathogenesis of this complex disease. Recent studies have investigated the potential role of human papillomavirus (HPV) infection in the development of endometriotic lesions. The objective of this review was to conduct a search of online databases (Embase, Medline and PubMed) for available literature from June 2013 to June 2023 concerning the association between HPV and endometriosis. After screening 110 articles, 23 studies met the eligibility criteria, and 8 were included in the systematic review. Out of the 8 reviewed papers, 3 described a statistically significant correlation between HPV infection and endometriosis. 3 others only demonstrated a higher incidence of HPV infection in patients with confirmed endometriosis. A difference in the dominant type of HPV serotype among patients diagnosed with endometriosis was also observed. Given these results, it is difficult to propose a viral origin of the disease. Further research is necessary to determine the role of HPV infection in the development of endometriosis. [ABSTRACT FROM AUTHOR]

Objectives: Angiogenesis is a process that is indispensable in cancer progression. A complex network of tumor and microenvironment stimuli regulate angiogenesis. VEGF, TGF-β1, IL-8 and TNF belong to the angiogenic factors that are key points in vessel formation. The aim of the study was to assess h-VEGF, TGF-β1, IL-8 and TNF secretion by human ovarian cell lines. Material and methods: OVA 2, OVA 4, OVA 9, OVA 11 and OVA 14 cell lines were established in our laboratory. The cells derived from primary and metastatic tumors of epithelial and non-epithelial origin. SK-OV-3, MDAH 2774, CAOV-1 and OVP-10 were the cell lines obtained from other sources. The concentration of VEGF, TGF-β1 and IL-8 was determined in culture supernatants by using the ELISA tests. Results: OVA 11 secreted all the evaluated cytokines. MDAH 2774 was the source of h-VEGF, TGF-β1, IL-8. SK-OV-3 secreted h-VEGF and IL-8. OVA 4 secreted TGF-β1 and TNF. TNF was the only studied cytokine secreted by CAOV-1, OVA 2 and OVA 9 cell lines. OVA 14 did not secret any of the cytokines. Conclusions: The investigated cell lines present heterogeneous profile of angiogenic cytokine secretion and seem to be an interesting set of models for the study of angiogenic signaling, or target therapy.

The purpose of this study was to determine the TNF-alpha-stimulatory effect of a novel immunomodulator 2-(1-adamantylamino)-6-methylpyridine (AdAMP) on normal and neoplastic human cells. In a panel of several human ovarian cancer cell lines, almost half of them spontaneously secreted significant amounts of TNF-alpha. When incubated with AdAMP, a 3-fold enhancement of TNF-alpha production by cells was observed. Furthermore, the phorbol myristic acetate ester (PMA)-induced release of TNF-alpha in cultures of U937 cells was increased in the presence of AdAMP. Primary monocytes isolated from peripheral blood did not respond to AdAMP. Although cytokine release was not triggered in human peripheral blood monocytes, AdAMP co-stimulated these cells to produce TNF-alpha and IL-8 during incubation with lipopolysaccharide (LPS). No effect of AdAMP was found on IL-1beta and IL-6 production by monocytes. In cultures of peripheral blood T lymphocytes, AdAMP significantly decreased the adhesion of these cells to matrix proteins in an in vitro assay. The results suggest that AdAMP, as a stimulator of cytokine secretion, may have potential application in tumor therapy.

Purpose: The unique mechanism of tumor destruction by photodynamic therapy (PDT), resulting from apoptotic and necrotic killing of tumor cells accompanied by local inflammatory reaction and induction of heat shock proteins (HSPs), prompted us to investigate the antitumor effectiveness of the combination of PDT with administration of immature dendritic cells (DCs)., Experimental Design: Confocal microscopy and Western blotting were used to investigate the influence of PDT on the induction of apoptosis and expression of HSP expression in C-26 cells. Confocal microscopy and flow cytometry studies were used to examine phagocytosis of PDT-treated C-26 cells by DCs. Secretion of interleukin (IL)-12 was measured with ELISA. Cytotoxic activity of lymph node cells was evaluated in a standard (51)Cr-release assay. The antitumor effectiveness of PDT in combination with administration of DCs was investigated in in vivo model., Results: PDT treatment resulted in the induction of apoptotic and necrotic cell death and expression of HSP27, HSP60, HSP72/73, HSP90, HO-1, and GRP78 in C-26 cells. Immature DCs cocultured with PDT-treated C-26 cells efficiently engulfed killed tumor cells, acquired functional features of maturation, and produced substantial amounts of IL-12. Inoculation of immature DCs into the PDT-treated tumors resulted in effective homing to regional and peripheral lymph nodes and stimulation of cytotoxic activity of T and natural killer cells. The combination treatment with PDT and administration of DCs produced effective antitumor response., Conclusions: The feasibility and antitumor effectiveness demonstrated in these studies suggest that treatment protocols involving the administration of immature DCs in combination with PDT may have clinical potential.
