AI Article Synopsis
- This study investigates the role of miR-206 in endometriosis (EM), previously known as a tumor suppressor in bladder cancer.
- Researchers analyzed samples from 40 EM patients, finding that miR-206 levels were lower in EM, and that increasing miR-206 reduced cell growth and promoted cell death in endometrial stromal cells (ESCs).
- The study also established that MALAT1, which was elevated in EM, is targeted by miR-206, indicating that miR-206 could be a potential therapeutic target for treating EM.
Article Abstract
Background: miR-206 was reported to be a tumor suppressor in bladder cancer. In this study, we explore the expression and function of miR-206 in endometriosis (EM).
Methods: 40 EM patients undergoing total hysterectomy were selected as the experimental group. RT-qPCR assay was adopted to detect the expression of MALAT1 and miR-206 in EM. Cell proliferation was detected by EdU incorporation and colony formation assay. Cell migration and invasion viability of ESCs were examined by transwell assay and wound healing assay. Flow cytometry was carried out to assess cell apoptosis of ESCs. The protein expressions of Bcl-2 and Bax were examined by western blot assay. The relationship between miR-206 and MALAT1 was verified by the dual-luciferase reporter assay and RNA pull-down assay.
Results: In this work, miR-206 was found to be downregulated in EM. Functional experiments displayed that miR-206 mimic repressed cell proliferation, migration, and invasion of ESCs and promoted cell apoptosis of ESCs. Furthermore, miR-206 mimic reduced the expression of Bcl-2 but enhanced the expression of Bax. MALAT1 was found to be upregulated in EM. Furthermore, MALAT1 was indicated to be a target of miR-206. Additionally, MALAT1 was found to alleviate the influence of miR-206 on cell progression of ESCs. Furthermore, miR-206 inhibited tumor growth .
Conclusion: This study indicated that miR-206 inhibited cell progression by regulating MALAT1 in EM. Hence, miR-206 was suggested to be a possible target for EM treatment.

Background: The ovary is a central organ in the reproductive system that produces oocytes and synthesizes and secretes steroid hormones. Healthy development and regular cyclical change in the ovary is crucial for regulating reproductive processes. However, the key genes and metabolites that regulate ovarian development and pregnancy have not been fully elucidated.

Inflammatory skin diseases impose a significant burden on patients and healthcare systems worldwide. Among these, hidradenitis suppurativa (HS) is particularly notable for its chronic and recurrent nature. Recurrent nodules, abscesses, and scarring in apocrine gland-rich areas characterize the disease, including the groin, axillae, and perianal regions.

Objective: This study sought to investigate the diagnostic value and the effect of microRNA (miR)-206 on drug resistance in pulmonary tuberculosis (TB) patients.
Methods: This study included 88 TB patients (TB group) as study subjects, 80 healthy subjects as control 1 (Control group), and 85 latent TB infection (LTBI) patients as control 2 (LTBI group). The drug resistance of TB patients after standard anti-TB treatment was recorded.

The level of miR-206-3p in the plasma and temporal cortex is increased in Alzheimer's disease (AD) patients. miR-206-3p antagomir injected into hippocampus ameliorates cognitive deficits by enhancing the level of BDNF. However, the trauma caused by brain injection and susceptibility to degradation limit its application.
