Invasive lung myofibroblasts are the main cause of tissue remodeling in idiopathic pulmonary fibrosis (IPF). A key mechanism contributing to this important feature is aberrant crosstalk between the abnormal/injured lung epithelium and pulmonary fibroblasts. Here, we demonstrate that lungs from patients with IPF and from mice with bleomycin (BLM)-induced pulmonary fibrosis (PF) are characterized by the induction of human epididymis protein 4 (HE4) overexpression in epithelial cells.

Post-hepatectomy liver failure (PHLF) is a potentially life-threatening complication following liver resection. Hepatocellular carcinoma (HCC) often occurs in patients with chronic liver disease, which increases the risk of PHLF. This study aimed to investigate the ability of the combination of liver function and fibrosis markers (ALBI score and FIB-4 index) to predict PHLF in patients with HCC.

Article Synopsis
  • Light significantly impacts the behavior, growth, and energy metabolism of the aquatic animal Scylla paramamosain, with different light colors affecting growth and molting rates.
  • The study utilized RNA-seq and qPCR to analyze differentially expressed genes in the eyestalks of S. paramamosain exposed to full-spectrum, violet, and cyan light, revealing thousands of DEGs and insights into their molecular functions.
  • Findings indicate that violet light reduces growth performance by impairing immunity, protein synthesis, and chitin metabolism, while full-spectrum and cyan lights promote these biological processes.

  • Praxelis clematidea is an invasive herbaceous plant found in Hainan Province, China, exhibiting severe witches'-broom symptoms indicative of a phytoplasma infection.
  • Researchers collected and analyzed samples from symptomatic and asymptomatic plants, confirming that the symptomatic plants tested positive for phytoplasma using direct PCR amplification of specific gene sequences.
  • The gene sequences obtained were identical and closely related to strains linked to major plant diseases, with a 100% identity match to specific 'Candidatus Phytoplasma asteris' strains, and were deposited in Genbank for further study.

  • WRKY transcription factors (TFs) play a significant role in producing secondary metabolites like betalains in plants, but their function in amaranth remains largely unexplored.
  • A study identified 72 WRKY genes in the amaranth transcriptome and found three specific genes linked to betalain synthesis, demonstrating higher expression levels in the red amaranth variety compared to the green one.
  • Through various genetic techniques, the research revealed that overexpressing one of the genes can enhance expression related to betalain production, suggesting potential pathways to boost these pigments in crops.
