Visualization of Hg Stress on Plant Health at the Subcellular Level Revealed by a Highly Sensitive Fluorescent Sensor.

The presence of Hg causes substantial stress to plants, adversely affecting growth and health by disrupting cell cycle divisions, photosynthesis, and ionic homeostasis. Accurate visualization of the spatiotemporal distribution of Hg in plant tissues is crucial for the management of Hg pollution; however, the related research is still at its early stage. Herein, a small-molecule amphiphilic fluorescent probe (termed ) was developed for the specific detection of Hg with a high sensitivity (~16 nM).

FGF20 Secreted From Dermal Papilla Cells Regulate the Proliferation and Differentiation of Hair Follicle Stem Cells in Fine-Wool Sheep.

Wool traits determine the market value of fine-wool sheep, and wool fibre-breaking elongation (fibres can be stretched or elongated before they break) is one of the important wool traits. The interaction between hair follicle stem cells (HFSCs) and dermal papilla cells (DPCs) determines hair follicle development in fine wool sheep, thereby directly influencing wool traits. A genome-wide association study based on pre-sequencing data identified FGF20, which was significantly associated with wool fibre-breaking elongation.

Noninvasive detection of twin zygosity using genome-wide linkage disequilibrium information.

Transcriptome and metabolome revealed the effects of hypoxic environment on ovarian development of Tibetan sheep.

Many studies on the adaptability of Tibetan sheep to hypoxia have been reported, but little attention has been paid to the reproduction of Tibetan sheep living at an altitude of more than 4000 m. In this study, the ovaries of Alpine Merino sheep (AM) living in middle-high altitude areas (2500 m) and the ovaries of Gangba Tibetan sheep (GB) and Huoba Tibetan sheep (HB) living in ultra-high altitude areas (4400 m or more) were collected. Through morphological, transcriptomics and metabolomics, the effects of ultra-high altitude areas on Tibetan sheep ovarian development and the molecular mechanism of sheep's adaptability to ultra-high altitude environment were explored.

Trim21 modulates endoplasmic reticulum-associated degradation and sensitizes cancer cells to ER stress-induced apoptosis by inhibiting VCP/Npl4/UFD1 assembly.

Endoplasmic reticulum-associated degradation (ERAD) serves as a crucial quality and quantity control system that removes misfolded or unassembled proteins from the Endoplasmic Reticulum (ER) through the cytoplasmic ubiquitin-proteasome system (UPS), which is critical for cell fate decision. ER stress arises when misfolded proteins accumulated within the ER lumen, potentially leading to cell death via proapoptotic unfolded protein response (UPR). UFD1 in associated with VCP-Npl4, is recognized as a key regulator of protein homeostasis in ERAD.
