Investigation into the Relationship between Spermidine Degradation and Phenolic Compounds Biosynthesis in Barley Seedlings under Ultraviolet B Stress

Plants, 2023
Barley germination under ultraviolet B (UV-B) illumination stress induces effective accumulation of phenolic compounds in the barley. Spermidine can enhance the biosynthesis of phenolic compounds and alleviate the oxidative damage caused by UV-B.

Exogenous Spermidine Promotes Germination of Aged Sorghum Seeds by Mediating Sugar Metabolism

Plants, 2022
Starch, a substance stored in seeds, is the main source of energy for germination in sorghum seeds. However, as the seeds age, the catabolism of seed starch is affected, thereby seriously damaging germination ability.

Non-monotonic swelling of a macroion due to correlation-induced charge inversion [PDF]

, 2008
It is known that a large, charged body immersed in a solution of multivalent counterions may undergo charge inversion as the counterions adsorb to its surface.

Improving PARP inhibitor efficacy in bladder cancer without genetic BRCAness by combination with PLX51107

Molecular Oncology, EarlyView.
Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

Spermidine intake is associated with cortical thickness and hippocampal volume in older adults

NeuroImage, 2020
Background: The natural polyamine spermidine, known to be important for cellular function, decreases during aging. Previous research has demonstrated beneficial impact of spermidine intake on memory functions in both animal models and humans, suggesting ...

Synthetic metallomolecules as agents for the control of DNA structure [PDF]

, 2007
This tutorial review summarises B-DNA structure and metallomolecule binding modes and illustrates some DNA structures induced by molecules containing metallic cations. The effects of aquated metal ions, cobalt amines, ruthenium octahedral metal complexes,

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells

FEBS Open Bio, EarlyView.
Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.

Spermidine-induced improvements in water relations and antioxidant defense enhance drought tolerance in yarrow (Achillea millefolium L.)

Heliyon
Drought stress poses a serious threat to agricultural productivity worldwide. This study investigated the mitigative effects of exogenous spermidine on drought stressed yarrow (Achillea millefolium L.). Plants were subjected to three drought levels (25 %,
