Emerging evidence indicates that postmenopausal women with periodontitis have aggravated inflammation and prolonged course, with the detailed mechanisms largely unknown. This study aimed to determine the pathogenic role of aberrant extracellular vesicles due to imbalanced-polarized macrophages and explore the therapeutic approach for periodontitis in postmenopausal individuals. Periodontitis in ovariectomized (OVX) mouse models were established to simulate the aggravated periodontitis in postmenopausal women.
RNA binding proteins are critical to the maintenance of the transcriptome via controlled regulation of RNA processing and transport. Alterations of these proteins impact multiple steps of the RNA life cycle resulting in various molecular phenotypes such as aberrant RNA splicing, transport, and stability. Disruption of RNA binding proteins and widespread RNA processing defects are increasingly recognized as critical determinants of neurological diseases.

Portrait of Joan Steitz
Joan Steitz radiates a passion for science. Whether she's teaching an undergraduate course, mentoring a grad student or post-doc, or speaking at a scientific conference, her enthusiasm and curiosity for all things RNA is infectious. Joan, the recipient of the 2018 Lasker-Koshland Special Achievement Award in Medical Science, spoke with Cell editor (and her former post-doc) Lara Szewczak about how she came to be an advocate for women in science and shared advice for young scientists entering the research community today.
