Chronic PM exposure disrupts intestinal barrier integrity via microbial dysbiosis-triggered TLR2/5-MyD88-NLRP3 inflammasome activation.

Background: PM, a known public health risk, is increasingly linked to intestinal disorders, however, the mechanisms of its impact are not fully understood.

Purpose: This study aimed to explore the impact of chronic PM exposure on intestinal barrier integrity and to uncover the underlying molecular mechanisms.

Methods: C57BL/6 J mice were exposed to either concentrated ambient PM (CPM) or filtered air (FA) for six months to simulate urban pollution conditions.

Explore the alterations of downstream molecular pathways caused by ARID1A mutation/knockout in human endometrial cancer cells.

Purpose: As one of the most common gynecologic malignancies, endometrial cancer (EC) is driven by multiple genetic alterations that may be targeted for treatments. AT-rich interaction domain 1A (ARID1A) gene mutations were reported as early events in endometrial carcinogenesis.

Methods: To explore the alterations of downstream molecular pathways caused by ARID1A mutations and the associated therapeutic implications, we edited ARID1A gene in human endometrial cancer cell line Ishikawa using the Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-Associated Proteins (CRISPR/Cas9) technology.

Association between common vaginal and HPV infections and results of cytology test in the Zhoupu District, Shanghai City, China, from 2014 to 2019.

Background: HPV (human papillomavirus) is an important cause of cervical cancer. Cervical-vaginal infection with pathogens, such as herpes simplex virus (HSV), bacterial vaginosis Trichomonas vaginalis and vaginal candidiasis could be a cofactor. This study aimed to assess the relationship between vaginal infection with HPV genotype and cytology test results and analyze the relationship between vaginal and HPV infections and cervical cancer.

Characteristics of human papillomavirus infection among women with cervical cytological abnormalities in the Zhoupu District, Shanghai City, China, 2014-2019.

Background: Human papillomavirus (HPV) infection is currently the main cause of cervical cancer and precancerous lesions in female patients. By analyzing 6-year patient data from Shanghai Zhoupu Hospital in China, we retrospectively analyzed the epidemiological characteristics of women to determine the relationship between HPV genotype and cytological test results.

Methods: From 2014 to 2019, 23,724 cases of cervical shedding were collected from Zhoupu Hospital in Shanghai, China.

Up regulation of miR-96-5p is responsible for TiO NPs induced invasion dysfunction of human trophoblastic cells via disturbing Ezrin mediated cytoskeletons arrangement.

Titanium dioxide nanoparticles (TiO NPs) are used extensively in our daily lives, and their toxic effects on the placenta have been reported. Animal studies indicated that placental development is impaired after maternal exposure of TiO NPs, but the underlying mechanisms remain largely unknown. In the present study, we used a human trophoblast-derived cell, HTR8-SVneo, to determine how TiO NPs affected placental functions, and found out potential reversal targets.

CRISPR/Cas9-Mediated Gene Knockout of ARID1A Promotes Primary Progesterone Resistance by Downregulating Progesterone Receptor B in Endometrial Cancer Cells.

Medroxyprogesterone (MPA) is used for the conservative treatment of endometrial cancer. Unfortunately, progesterone resistance seriously affects its therapeutic effect. The purpose of the current study was to investigate the influence of deletion of AT-rich interactive domain 1A (ARID1A) in progesterone resistance in Ishikawa cells.

Associated analysis of DNA methylation for cancer detection using CCP-based FRET technique.

This paper describes an associated analysis method of DNA methylation for the detection of cancer using an optically amplifying cationic conjugated polymer (CCP, poly{(1,4-phenylene)-2,7-[9,9-bis(6'-N,N,N-trimethyl ammonium)-hexyl fluorene] dibromide)}. Genomic DNA is digested by methylation-sensitive restriction endonuclease, followed by PCR amplification to incorporate fluorescein-labeled dNTP. Only methylated DNA can be amplified by PCR, and the methylation level is detected through fluorescence resonance energy transfer (FRET) between CCP and fluorescein that is incorporated into the PCR product.

Does ceruloplasmin differential express in the brain of Ts65Dn: a mouse mode of Down syndrome?

To investigate the expression of CP in Down syndrome (DS) mouse model, we especially observed the changes in neuronal CP. We systematically analyzed the level of CP in Ts65Dn mouse, including serum CP concentration and enzymatic activity, CP mRNA in brain, the expression of CP protein in brain. The applied technologies were ELISA, chemical colorimetry, RT-PCR, immunohistochemistry.

Therapeutic effect of Fe2O3 nanoparticles combined with magnetic fluid hyperthermia on cultured liver cancer cells and xenograft liver cancers.

The therapeutic effect of Fe2O3 nanoparticles combined with magnetic fluid hyperthermia (MFH) on human hepatocarcinoma SMMC-7721 cells in vitro and xenograft liver cancer in nude mice is studied. We examined growth and apoptosis of SMMC-7721 cells treated with MFH containing Fe2O3 nanoparticles at various concentrations (2, 4, 6, and 8 g/liter) for 30-60 min by using MTT, flow cytometry (FCM), and transmission electron microscopy (TEM). We also observed weight and volume inhibitory rates of the tumors of SMMC-7721-bearing nude mice by using animal experiments.
