New insights into interspecies relationships, chromosomal evolution, and hybrid identification in the Lycoris Herb.
BMC Plant Biol

Background: Frequent interspecific hybridization, unclear genetic backgrounds, and ambiguous evolutionary relationships within the genus Lycoris pose significant challenges to the identification and classification of hybrids, thereby impacting the application and development of Lycoris. This study utilizes karyotype structure, genome size, and fluorescent in situ hybridization (FISH) technology to explore the chromosomal evolution and hybrid identification of Lycoris employing three approaches at the cytogenetic level.
Results: The findings indicate that species with a smaller basic chromosome number exhibit less asymmetry than those with a larger basic chromosome number, suggesting that species with different basic chromosome numbers may have followed different evolutionary pathways.
Genetic Characteristics of the Rat Fibroblast Cell Line Rat-1.

December 2024
Institute of Molecular Pathobiochemistry, Experimental Gene Therapy and Clinical Chemistry (IFMPEGKC), RWTH, University Hospital Aachen, D-52074 Aachen, Germany.
The Rat-1 cell line was established as a subclone of the parental rat fibroblastoid line F2408, derived from Fisher 344 rat embryos. Rat-1 cells are widely used in various research fields, especially in cancer biology, to study the effects of oncogenes on cell proliferation. They are also crucial for investigating signal transduction pathways and play a key role in drug testing and pharmacological studies due to their rapid proliferation.

Article Synopsis
- Patient-derived xenografts (PDXs) offer a valuable approach to study breast cancer (BC) by mimicking real tumor environments and systemic effects, which in vitro models cannot achieve.
- A new method for orthotopic implantation of BC PDXs in immunodeficient mice eliminates the need for anesthesia, is less invasive, and allows for faster and scalable tumor model development.
- The validation process of the tumors includes assessing receptor status, confirming morphology, and verifying genetic similarity to patient samples, facilitating robust research across different BC subtypes.
Ginsenoside Rk1 exerts protective effects of LPS-induced podocyte apoptosis and inflammation by inactivating JAK2/STAT3 and NF-κB pathways.

Internal Medicine Department, Shenzhen Bao'an Authentic TCM Therapy Hospital, Shenzhen, China.
Podocyte injury is a major biomarker of primary glomerular disease that leads to massive proteinuria and kidney failure. Ginsenoside Rk1, a substance derived from ginseng, has several pharmacological activities, such as anti-apoptotic, anti-inflammatory, and antioxidant effects. In this study, our goal is to investigate the roles and mechanisms of ginsenoside Rk1 in podocyte injury and acute kidney injury (AKI).
