Summary: Endometrosis, a common disease that affects mares' fertility, is associated with alterations in epithelial and stromal cells, as well as degeneration and fibrosis of the endometrium. The study reveals a potential involvement of the NF-kappa B pathway in the pathogenesis of endometrosis, showing differential transcription of profibrotic genes between different phases of the estrous cycle. Additionally, the transcription of estrogen and progesterone receptors is found to be decreased with the severity of fibrosis and degeneration of the endometrium in horses.

Summary: Increasing evidence suggests that long non-coding RNAs (lncRNAs) play important roles in various biological processes. However, there is little research on the functional roles of lncRNAs in teleost fish. In this study, a novel lncRNA (linc-93.2) was identified in common carp macrophages after exposure to the endocrine disrupting chemical BPA. The results showed that linc-93.2 is involved in the immune and neurological functions of fish.

Summary: This study found that decreased estrogen receptor alpha (ER alpha) levels are associated with cellular senescence in osteoarthritis (OA) chondrocytes. Overexpressing ER alpha can reduce DNA damage and senescence levels in chondrocytes. These findings suggest that maintaining ER alpha levels may be a new approach to prevent and treat OA.

Summary: Breast cancer, with 70% expressing ER alpha, is a heterogeneous disease and the leading cause of female cancer mortality globally. HOXA1, a master regulator of embryo development, has been found to have a functional antagonism with ER alpha, able to inhibit its activity through DNA-binding mechanisms and interaction with NF-kappa B. Although HOXA1 can physically interact with ER alpha, this interaction is not essential for its inhibition on ER alpha.

Summary: This review discusses the impact and role of the NF-kappa B pathway on the development and progression of various endometrial diseases. NF-kappa B modulates immune responses in endometritis, endometrosis, endometriosis, and endometrial carcinoma, leading to changes in cell migration, proliferation, and inflammation intensity. The dysregulation of the immune system involving NF-kappa B-induced chemokine and cytokine production contributes to the pathogenesis of these diseases. Additionally, the influence of estrogen and progesterone cannot be overlooked in the regulation of endometrial diseases.

Summary: This study elucidated the role of MLPH in GBM radiation resistance, showing that MLPH promotes radiotherapy resistance by regulating the NF-kappa B pathway. Additionally, O-GlcNAcylation of MLPH protects it from degradation and stabilizes its presence in cells. These findings provide insights into a potential mechanism of GBM radiation resistance and suggest a therapeutic strategy for GBM treatment.

Summary: Endometritis is a common reproductive disease in domestic animals caused by Gram-negative bacterial infection, where the ISGylation modification system can regulate the inflammatory response by modulating the TLR4/NF-kappa B signaling pathway. Experimental evidence shows that ISG15 can inhibit LPS-induced inflammatory response through ISGylation.

Summary: This study found a correlation between the epithelial-to-mesenchymal transition (EMT) of melanoma cells and the expression of estrogen receptor beta (ERβ). Extracellular acidosis induced an enhanced expression of ERβ in female cells, while not inducing its expression in male cells, and promoted EMT. ERβ was also found to regulate EMT through NF-kappa B activation.

Summary: Various stressors can have profound impacts on immunity to pathogens, with little research into the effects of cyanobacterial toxins on disease resistance in mammals. Recent studies suggest that freshwater cyanotoxins may alter disease susceptibility parameters for fish, wildlife, and human health through interaction with specific components of innate immunity. However, the results of this study indicate that the tested toxins did not directly interact with key pathogen recognition receptors for innate immunity in humans.

Summary: Post-menopausal women have a higher risk of developing Alzheimer's disease compared to men due to the decline in estrogen levels. Estrogen downregulates inflammatory cytokines in the central nervous system, providing neuroprotection against neurodegenerative diseases like AD. Neuroinflammation is associated with neurodegeneration and contributes to AD. The transcription factor NF-kappa B interacts with estrogen to modulate inflammation and influence the progression of AD. Further research on the interaction between NF-kappa B and estrogen could lead to the development of novel therapeutics.

Summary: This study demonstrates that montelukast is effective at reducing arsenic-induced epithelial-mesenchymal transition (EMT) in human bronchial epithelial cells. By inhibiting arsenic-induced reactive oxygen species (ROS) generation and NF-kB activation, montelukast can suppress arsenic-induced cell migration and the expression of extracellular matrix proteins and EMT-regulating transcription factors. Combination treatment with fluticasone and montelukast can reverse the inhibitory effect of montelukast on arsenic-induced EMT.

Summary: Abnormal uterine bleeding can adversely affect the physical and mental health of individuals who menstruate. This Review explores the causes and physiology of abnormal uterine bleeding. Menstruation is a normal physiological process, but one third of women globally experience abnormal uterine bleeding during their reproductive years. Imbalances in various stages of endometrial shedding can result in the abnormal endometrial phenotype of abnormal uterine bleeding. Iron deficiency and iron deficiency anemia are closely associated with abnormal uterine bleeding, but are often underestimated and under-recognized. The International Federation of Gynecology and Obstetrics has established standardized terminology and classification system for abnormal uterine bleeding, facilitating future research, diagnosis, and clinical management. Emerging technologies are providing new insights into the biology of the endometrium in health and disease and presenting new diagnostic and management approaches.

Summary: Eosinophils play a crucial role in inducing a complete vaccine response, promoting antibody secretion in the early stage of the immune response. They migrate to the lungs and secrete cytokines to activate B cells, promoting antibody production. However, the absence of eosinophils does not impair late immune responses due to a compensating mechanism involving the Th17 pathway. This study reveals a novel role for eosinophils in lung mucosal vaccination, accelerating early immune responses while regulating IgA production in the late stages.

Summary: Chronic pain induced by endometriosis is a significant issue for women, but there is a lack of long-term pharmacological treatments that can relieve pain without affecting fertility. The absence of a reliable rodent model that replicates human physiopathological characteristics, including pain symptoms, has hindered progress in this field. This study reviewed the existing endometriosis models in rodents and examined the type of behavioral tests used to evaluate pain. The findings identified both reflex and non-reflex tests that can be utilized to study endometriosis-induced pain.

Summary: This review discusses the biology of sex steroids, regulation of mammalian liver physiology, and the development of new model systems to enhance understanding of liver biology in health and disease. Hepatic fibrosis is a major risk factor for liver disease, driven by metabolic dysfunction and pathological immune activation. Non-alcoholic fatty liver disease (NAFLD) can progress to non-alcoholic steatohepatitis, increasing the risk of cirrhosis and hepatocellular carcinoma. Obesity and insulin resistance, as well as sex and age, are important risk factors for NAFLD. Sex hormones also play a role in regulating liver metabolism and the immune system, emphasizing the importance of considering sex differences in liver disease treatment strategies.

Genetic, hormonal, and immunological factors may contribute to the risk of developing lesions. Studies have identified specific genes and genetic variants associated with endometriosis, suggesting shared risk factors with other reproductive disorders. Further research is needed to understand the role of these genes and their contribution to different forms of endometriosis.

Summary: The human endometrium undergoes cycles of proliferation, differentiation, and breakdown during a woman's reproductive lifetime. Understanding mechanisms of scarless repair of the endometrium is important for treating related conditions and reducing fibrosis in other tissues. Mouse models have been developed to study endometrial repair and simulate the process in women.
