Polycystic ovary syndrome (PCOS) affects 6%-10% of women of reproductive age and is known to be associated with disruptions in the gut bacteria. However, the role of the gut mycobiota in PCOS pathology remains unclear. Using culture-dependent and internal transcribed spacer 2 (ITS2)-sequencing methods, we discovered an enrichment of the gut-colonizable fungus Aspergillus tubingensis in 226 individuals, with or without PCOS, from 3 different geographical areas within China.

Expert consensus on pulpotomy in the management of mature permanent teeth with pulpitis.

Int J Oral Sci

January 2025

Department of Cariology and Endodontics, Wuhan University & State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, Key Laboratory of Oral Biomedicine Ministry of Education, Hubei Key Laboratory of Stomatology, School & Hospital of Stomatology, Wuhan University, Wuhan, China.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth.

January 2025

Cardiovascular Surgery Department of The First Affiliated Hospital of Harbin Medical University, and Pharmacology Department of Pharmacy College of Harbin Medical University, Harbin, 150081, China.

Myocardial ischemia/reperfusion (IR) injury is a common adverse event in the clinical treatment of myocardial ischemic disease. Autosis is a form of cell death that occurs when autophagy is excessive in cells, and it has been associated with cardiac IR damage. This study aimed to investigate the regulatory mechanism of circRNA CDR1AS on autosis in cardiomyocytes under IR.

Background: Tumor-derived small extracellular vesicles (sEVs) play an essential role in reprogramming the tumor microenvironment. Metabolic reprogramming is an essential prerequisite for M2 polarization of tumor-associated macrophages (TAMs). This M2 phenotype is closely related to the immune dysfunction of CD8 T cells and subsequent tumor progression.

Background: Inactivation or mutations of FAM20C causes human Raine Syndrome, which manifests as lethal osteosclerosis bone dysplasia or non-lethal hypophosphatemia rickets. However, it is only hypophosphatemia rickets that was reported in the mice with Fam20c deletion or mutations. To further investigate the local and global impacts of Fam20c mutation, we constructed a knock-in allele carrying Fam20c mutation (D446N) found in the non-lethal Raine Syndrome.

Article Synopsis
  • The study investigates the role of the CCL2/CCR2 signaling pathway in neuroinflammation following subarachnoid hemorrhage (SAH) and examines the neuroprotective effects of Bindarit, a CCL2 inhibitor.
  • Analysis of RNA-seq data showed increased CCL2 expression in SAH, and treatment with Bindarit improved neurological deficits and reduced inflammation in both in vivo and in vitro models.
  • The findings suggest that targeting the CCL2/CCR2 pathway with Bindarit may offer therapeutic benefits by enhancing neurological recovery after SAH.

Heme oxygenase 1 (HO-1), an enzyme involved in heme catabolism, has been shown upregulated in microglia cells and plays a critical roles in neurological damages after intracerebral hemorrhage (ICH). However, the mechanisms by which HO-1 mediates the neuronal damages are still obscure. Here, our findings demonstrate that HO-1 over-expression exacerbates the pro-inflammatory response of microglia and induces neuronal ferroptosis through promoting intracellular iron deposition in the ICH model both in vitro and in vivo.

Genome-wide analysis of alternative splicing differences in hepatic ischemia reperfusion injury.

Sci Rep

December 2024

Department of Minimally Invasive Hepatic Surgery, Key Laboratory of Hepatosplenic Surgery, the First Affiliated Hospital of Harbin Medical University, Ministry of Education, Harbin, Heilongjiang, China.

Alternative splicing (AS) contributes to transcript and protein diversity, affecting their structure and function. However, the specific transcriptional regulatory mechanisms underlying AS in the context of hepatic ischemia reperfusion (IR) injury in mice have not been extensively characterized. In this study, we investigated differentially alternatively spliced (DAS) genes and differentially expressed transcripts (DETs) in a mouse model of hepatic IR injury using the high throughput RNA sequencing (RNA-seq) analysis and replicate multivariate analysis of transcript splicing (rMATS) analysis.
