The ortholog of human DNAJC9 promotes histone H3-H4 degradation and is counteracted by Asf1 in fission yeast.

Mammalian J-domain protein DNAJC9 interacts with histones H3-H4 and is important for cell proliferation. However, its exact function remains unclear. Here, we show that, in the fission yeast Schizosaccharomyces pombe, loss of Djc9, the ortholog of DNAJC9, renders the histone chaperone Asf1 no longer essential for growth.

WBSCR16 is essential for mitochondrial 16S rRNA processing in mammals.

Mitochondrial rRNAs play important roles in regulating mtDNA-encoded gene expression and energy metabolism subsequently. However, the proteins that regulate mitochondrial 16S rRNA processing remain poorly understood. Herein, we generated adipose-specific Wbscr16-/-mice and cells, both of which exhibited dramatic mitochondrial changes.

Influenza A virus NS2 protein acts on vRNA-resident polymerase to drive the transcription to replication switch.

The heterotrimeric RNA-dependent RNA polymerase (RdRp) of influenza A virus catalyzes viral RNA transcription (vRNA→mRNA) and replication (vRNA→cRNA→vRNA) by adopting different conformations. A switch from transcription to replication occurs at a relatively late stage of infection. We recently reported that the viral NS2 protein, expressed at later stages from a spliced transcript of the NS segment messenger RNA (mRNA), inhibits transcription, promotes replication and plays a key role in the transcription-to-replication switch.

Reassessing the Role of Low PSA in Prognosis Across Grades of Prostate Cancer: A Cohort Study.

Background: Prior studies have concentrated exclusively on how different prostate-specific antigen (PSA) levels affect the prognosis of high-grade prostate cancer (PCa), often overlooking the prognosis of low-grade PCa.

Methods: The present cohort study included individuals diagnosed with PCa from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2021. The all-cause mortality (ACM) and prostate cancer-specific mortality (PCSM) for each treatment group was calculated stratified by the four PSA levels (≤ 4.

A novel mouse model of pulmonary fibrosis: twice-repeated oropharyngeal bleomycin administration mimicking human pathology.

Idiopathic pulmonary fibrosis (IPF) is a progressive and irreversible lung disease with high mortality and limited treatment options. While single-dose bleomycin-induced models are commonly used to investigate the pathogenesis of IPF, they fail to adequately replicate the complex pathological features in human patients, thereby hindering comprehensive investigations. Previous studies utilizing repetitive bleomycin injections have demonstrated a closer resemblance to human IPF pathology; however, the time- and resource-intensive nature of this approach presents significant drawbacks.

A phytocytokine and its derived peptides in the frass of an insect elicit rice defenses.

Upon recognizing elicitors derived from herbivores, many plants activate specific defenses. Most of the elicitors identified thus far are from the oral secretions and egg-laying fluids of herbivores; in contrast, herbivore fecal excreta have been sparsely studied in this context. In this study, we identified elicitors in the frass of the striped stem borer (SSB; Chilo suppressalis) larvae using a combination of molecular and chemical analyses, bioactivity tests and insect performance bioassays.

Effect of virtual reality intervention on hospitalized patients with acute pain after thoracoscopic surgery: a pilot randomized clinical trial.
