Article Abstract
Objective: miR-663a has been reported to be downregulated by X-ray irradiation and participates in radiation-induced bystander effect TGF-β1. The goal of this study was to explore the role of miR-663a during radiation-induced Epithelium-to-mesenchymal transition (EMT).
Methods: TGF-β1 or IR was used to induce EMT. After miR-663a transfection, cell migration and cell morphological changes were detected and the expression levels of miR-663a, TGF-β1, and EMT-related factors were quantified.
Results: Enhancement of cell migration and promotion of mesenchymal changes induced by either TGF-β1 or radiation were suppressed by miR-663a. Furthermore, both X-ray and carbon ion irradiation resulted in the upregulation of TGF-β1 and downregulation of miR-663a, while the silencing of TGF-β1 by miR-663a reversed the EMT process after radiation.
Conclusion: Our findings demonstrate an EMT-suppressing effect by miR-663a TGF-β1 in radiation-induced EMT.

Study Question: What is the effect of hCG on the epigenetic profile and the expression of other molecular factors in endometrial stromal cells (ESCs)?
Summary Answer: Our findings suggest that hCG treatment alters the molecular environment of decidualized ESCs, potentially influencing implantation and immune regulation through epigenetic modifications and changes in the levels of secreted proteins and micro-ribonucleic acids (miRNAs).
What Is Known Already: Embryo implantation depends not only on the quality of the embryo but also on the receptivity of the endometrium, the specialized lining of the uterus that undergoes dynamic changes to support pregnancy. Effective communication between the maternal and fetal compartments, facilitated by molecular signals and cellular interactions, is essential for successful implantation.

Mitochondria dysfunction has been closely linked to a wide spectrum of human cancers, whereas the molecular basis has yet to be fully understood. SLC25A35 belongs to the SLC25 family of mitochondrial carrier proteins. However, the role of SLC25A35 in mitochondrial metabolism reprogramming, development and progression in human cancers remains unclear.

Background: Photon radiation has been shown to stimulate the secretion of radioresistant factors from tumor cells, ultimately promoting tumor angiogenesis and metastasis. On the other hand, heavy-ion radiotherapy has been demonstrated to control tumor angiogenesis and metastasis levels. The molecular mechanisms responsible for the different angiogenic responses to photon and heavy-ion irradiation are not fully understood.

Article Synopsis
- - The study explores how variations in the PRKCG gene's non-coding regions, specifically the 3' and 5' UTRs, affect gene expression and post-transcriptional regulation, focusing on variants that could influence transcription factor binding and RNA interactions.
- - Out of 419 UTR variants analyzed, 325 were deemed functionally significant, with specific variants linked to RNA binding proteins and regulatory mechanisms like histone modifications, as well as interactions with certain miRNAs in cancer.
- - Findings reveal that these non-coding variants may alter mRNA structure and affect splicing efficiency, emphasizing their potential role in developing targeted therapies for cancer and other diseases.

Background: Exposure to ambient ozone has been associated with extrapulmonary health, but the underlying mechanisms remain to be understood. LncRNAs are involved in the regulation of gene expression, but their regulatory mechanisms in ozone-related health effects are scarcely explored.
Objective: To investigate genome-wide lncRNA changes after short-term ozone exposure and their regulatory roles in ozone exposure and gene expression.
