AbstractErigeron breviscapus is a widely utilized medicinal herb in traditional Chinese medicine, characterized by high annual demand and notable pharmacological activities. Light intensity is a critical environmental factor influencing secondary metabolism in medicinal plants. However, the effects of light intensity on the accumulation of active ingredients in E. breviscapus remain largely unexplored. In this study, we examined the transcriptomic and metabolomic responses of E. breviscapus to five levels of light intensity (50, 100, 200, 400, 800 μmol·m−2·s−1). The results revealed that higher light intensity (EB-L800) significantly increased the accumulation of scutellarin, chlorogenic acid, isochlorogenic acid A, and isochlorogenic acid C. A total of 1,334 metabolites were detected, and 127.10 Gb of high-quality clean data were generated through transcriptomic sequencing.

The fusion of two cells is a decisive event in the sexual reproduction of many organisms. In fungi, cells must not only bring their membranes together and merge them, but also locally open their protective cell wall. A study conducted at the University of Geneva (UNIGE) shows how a mechanism that prevents cells from repairing their wall at the fusion site makes this process irreversible. Published in the journal Current Biology, these findings provide new insights into how cells coordinate fusion and repair mechanisms and could ultimately open new avenues for targeting the cell wall of pathogenic fungi. Unlike animal cells, fungal cells are surrounded by a rigid cell wall. This structure protects them and allows them to withstand the internal pressure exerted by their cellular contents. When two cells fuse, notably during sexual reproduction, this wall must be locally degraded to allow the membranes of the two cells to merge. Once this step has been completed, fusion normally proceeds until a single cell is formed.

AbstractFunctional recovery after spinal cord injury (SCI) remains challenging, requiring therapeutic targets. Here, we show that doublecortin-like kinase 1 (DCLK1) is upregulated after SCI in mice. Pharmacological inhibition of DCLK1 with DCLK1-IN-1 improved motor recovery, reduced glial scar formation and fibrosis, and preserved neurons at the lesion site. Mechanistically, we identified the microtubule-severing protein KATNA1 as a downstream target of DCLK1. DCLK1 directly phosphorylated KATNA1 at threonine 118 (T118), suppressing its microtubule-severing activity. DCLK1 overexpression inhibited, whereas DCLK1 knockdown or inhibition enhanced KATNA1 function. The T118D mutation reduced KATNA1 activity, while T118A resisted DCLK1-mediated suppression. In neurons, DCLK1 inhibited KATNA1-induced neurite outgrowth, whereas DCLK1 inhibition restored this effect.

Broaden observation dimensions to unlock untapped research insights with flexible multiple factors protein detection solutions HUSTON, TX, UNITED STATES, October 19, 2026 /EINPresswire.com/ -- Many researchers across universities, affiliated hospitals and research institutes are grappling with a shared challenge: difficulty sourcing original research topics, generating novel ideas and publishing high-quality papers. Even well-resourced laboratories with sufficient funding, complete experimental platforms and solid team capacity frequently hit a bottleneck in exploratory work. This article unpacks the root causes behind this widespread research dilemma and introduces an enabling tool to help researchers capture unexpected, high-value experimental signals during early-stage exploration. Many researchers in universities, affiliated hospitals and research institutes have recently encountered a common predicament: research topic shortage. This “topic shortage” does not stem from insufficient research funding, lack of experimental platforms or understaffed research groups.

Owners who spent more time physically close to their cats tended to report more positive moods, according to a new study by a Kyoto University-led team. The study, published in the journal iScience, came amid a common claim that caring for a feline friend has positive effects on human health and well-being while other studies reporting possible negative effects of cat ownership.
