The cell cycle is a fundamental process of plant growth, development, and reproduction, in which cyclin-dependent kinases (CDKs) and cyclins (CYCs) play central roles in regulating the progression through various stages. These proteins are coordinated with multiple interacting partners to ensure the accurate execution of essential biological events such as DNA replication, chromosome segregation, and cell division. Marchantia polymorpha, one of the earliest diverging land plant species, has emerged as a key model for exploring fundamental mechanisms in plant biology and evolution.

Stress-associated proteins (SAPs), characterized by zinc finger domains, play a crucial role in regulating plant responses to various stresses. These proteins modulate stress-related gene expression and are integral to enhancing plant immunity, development, cell proliferation, and hormone regulation. In this study, we conducted a genome-wide analysis of the SAP gene family in Suaeda glauca (S.

Article Synopsis
  • Homocysteine (Hcy) is a pro-inflammatory molecule that can cause oxidative damage and promote inflammation, especially in vascular cells, but its effects on intestinal inflammation are not well understood.
  • Researchers conducted a study with 99 IBD patients and 10 healthy individuals to investigate Hcy's role in increasing inflammatory mediators like LTE4 and PGE2, using both animal models and human cells for testing.
  • Results showed higher levels of Hcy, LTE4, and PGE2 in IBD patients, and Hcy significantly upregulated inflammatory markers and pathways in colitis rats, indicating its potential role in exacerbating intestinal inflammation.

Background: The close association between inflammation and the clinical outcomes of hepatocellular carcinoma (HCC) has been extensively documented. This study aims to analyze the association between a novel inflammatory indicator, the gamma-glutamyl transpeptidase to neutrophil ratio (GNR), and HCC prognosis following curative resection.

Methods: A cohort of 204 eligible HCC cases were included.

In plants, sexual reproduction relies on the proper development of floral organs that facilitate the successful development of fruits and seeds. Auxin responsive small auxin-up RNA (SAUR) genes play essential roles in floral organ formation and fruit development. However, little is known about the role of SAUR genes in pineapple floral organ formation and fruit development as well as stress responses.

In plants, sugars are required for several essential functions, including growth, storage, signaling, defense and reproduction. Sugar transporters carry out the controlled movement of sugars from source (leaves) to sink (fruits and roots) tissues and determine the overall development of the plant. Various types of sugar transporter families have been described in plants, including sucrose transporters (SUC/SUT), monosaccharide transporter (MST) and SWEET (from Sugar Will Eventually be Exported Transporters).
