p8 (NUPR1 (nuclear protein-1), Com1 (candidate of metastasis-1)) is a protein related to the high mobility group of transcriptional regulators. It is a key player in the cellular stress response and is involved in metastasis. p8 was first identified as a gene induced in pancreatitis but has been since found overexpressed in several cancers and pathological conditions. Despite its small size and apparently simple structure, p8 functions in several biochemical and genetic pathways, and its expression is crucial for in vivo metastasis in mice, for cytokine induction of metalloproteases, and for stress-induced cardiomyocyte hypertrophy. Understanding p8 functions will provide new opportunities for developing more effective therapeutic approaches to cancer and cardiovascular diseases.

Drought, as an abiotic stressor, globally limits cereal productivity, leading to early aging of leaves and lower yields. The expression of the isopentenyl transferase (IPT) gene, which is involved in cytokinin (CK) biosynthesis, can delay drought-induced leaf senescence. In this study, the Agrobacterium Isopentenyl transferase (IPT) gene was introduced into two local hexaploid wheat cultivars, NR-421 and FSD-2008.

Plasma membrane intrinsic proteins (PIPs), one sub-family of aquaporins (AQPs), are responsible for plant abiotic stress responses. However, little information is currently available about the stress responsiveness of the promoter in vegetable pea. In the present study, one novel promoter of which shared high similarity to the -type from other plants, was isolated.

Sestrin2 (SESN2) is a stress-inducible protein known for its cytoprotective functions, but its role in diabetic vascular complications remains unclear. This study investigated the impact of SESN2 on methylglyoxal (MGO)-induced endothelial-mesenchymal transition (EndMT). Human endothelial cells were transfected with SESN2 siRNA duplexes to silence SESN2 expression, followed by MGO treatment.

Background: DNA damage tolerance (DDT) enables replication to continue in the presence of fork stalling lesions. In mammalian cells, DDT is regulated by two independent pathways, controlled by the polymerase REV1 and ubiquitinated PCNA, respectively.
Results: To determine the molecular and genomic impact of a global DDT defect, we studied Pcna;Rev1 compound mutants in mouse cells.

Co-chaperones are key elements of cellular protein quality control. They cooperate with the major heat shock proteins Hsp70 and Hsp90 in folding proteins and preventing the toxic accumulation of misfolded proteins upon exposure to stress. Hsp90 interacts with the co-chaperone stress-inducible phosphoprotein 1 (Sti1/Stip1/Hop) and activator of Hsp90 ATPase protein 1 (Aha1) among many others.
