AI Article Synopsis
- Intrauterine adhesions (IUA) are common endometrial disorders that lead to menstrual issues and infertility, prompting a study on the role of SCGB1D4 in IUA tissues.
- The research involved comparing clinical data from IUA patients with control groups, using rat models and human cell lines to investigate SCGB1D4 expression and related fibrosis markers.
- Results showed lower SCGB1D4 levels in IUA patients, increased fibrosis indicators, and that enhancing SCGB1D4 in cell models inhibited cell growth and altered the cell cycle, suggesting potential therapeutic implications.
Article Abstract
Background: Intrauterine adhesions (IUA) represent a prevalent uterine endometrial disorder frequently correlated with menstrual irregularities and infertility. This study aims to examine the expression of SCGB1D4 in IUA tissues and assess its potential therapeutic implications by analyzing clinical features and constructing rat and cell models.
Methods: Clinical characteristics of patients with intrauterine adhesions were compared and analyzed against control subjects. Additionally, a rat uterine adhesion model was successfully established using a combination of mechanical injury and infection. The expression levels of SCGB1D4 in patient tissues and animal models were detected through immunohistochemistry, Western blot, and real-time fluorescence quantitative PCR, and the changes in fibrosis markers COL1A1 and α-SMA were also evaluated. Furthermore, human endometrial stromal cell lines (HESCs) induced by transforming growth factor-β-1 conversion were differentiated into myofibroblasts to establish cell models of intrauterine adhesion. We detected the expression of SCGB1D4 and fibrosis-related factors by real-time fluorescence quantitative PCR and Western blot. Cell proliferation and cell cycle changes were assessed using flow cytometry and CCK8.
Results: IUA patients showed increased miscarriage rates and decreased endometrial thickness. Clinical tissue specimens revealed significantly lower expression of SCGB1D4 in the endometrial tissues of IUA patients, accompanied by a notable increase in COL1A1 and α-SMA. The established rat model of intrauterine adhesion exhibited decreased expression of SCGB1D4 and a significant increase in fibrosis. After overexpression of SCGB1D4 on the IUA cell model, SCGB1D4 expression was elevated, while COL1A1 and α-SMA expression was significantly reduced. Cell proliferation was inhibited and cell cycle distribution was altered.
Conclusions: This study has confirmed the low expression of SCGB1D4 in patients with intrauterine adhesions (IUA), as well as in animal and cell models. Furthermore, the overexpression of SCGB1D4 in a cell model of IUA demonstrates that it may play a key role in inhibiting fibrosis. SCGB1D4 holds promise as a potential therapeutic target for IUA, providing a new avenue for overcoming fertility issues caused by intrauterine adhesions.

Background: The involvement of secretoglobins (SCGBs) other than SCGB1A1 (Clara cell 10-kDa protein, CC10) in human airway diseases remains unexplored. Among those SCGBs, SCGB3A2 (uteroglobin-related protein 1, UGRP1) is particularly interesting, given its structure and function similarities with SCGB1A1 (CC10). The aim of this study was to investigate the expression regulation of SCGBs other than SCGB1A1 (CC10) in human upper airway, and their potential involvement, particularly that of SCGB3A2 (UGRP1), in chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP).

Rats have been used to study the function and development of the mammalian prostate. Identification of prostatic secreted proteins is important in order to better understand their physiological function. Previous investigations have showed that prostatein, cysteine-related protein 1, and kallikrein S3 are in the ventral prostate (VP), whereas the proteins probasin, prostate secretory peptide 94, transglutaminase 4, and carbonic anhydrase II are produced in the lateral prostate, dorsal prostate (DP), and anterior prostate.

The fungicide fenarimol has estrogenic and antiandrogenic activity and inhibits aromatase activity in vitro. We tested, whether fenarimol had antiandrogenic effects in vivo. In a Hershberger assay, fenarimol given orally to castrated testosterone-treated male rats caused markedly reduced weights of ventral prostate, seminal vesicles, musc.

The acquisition of resistance to conventional therapies such as radiation and chemotherapeutic drugs remains the major obstacle in the successful treatment of cancer patients. Tumor cells acquire resistance to apoptotic stimuli and it has been demonstrated that conventional therapies exert their cytotoxic activities primarily by inducing apoptosis in the cells. Resistance to radiation and chemotherapeutic drugs has led to the development of immunotherapy and gene therapy approaches with the intent of overcoming resistance to drugs and radiation as well as enhancing the specificity to eliminate tumor cells.
