Revisiting the role of phenylpropanoids in plant defense against UV-B stress

Plant Stress, 2023
Ultraviolet-B (UV-B) radiation from the past few decades has been widely studied due to the substantial depletion of the stratospheric ozone (O3) layer, causing morphological, physiological, cytological, and biochemical alterations in plants. As a potent

Prochlorococcus and Synechococcus have evolved different adaptive mechanisms to cope with light and UV stress [PDF]

, 2012
Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on Earth. Although they require solar energy for photosynthesis, excess light and associated high UV radiations can induce ...

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

Molecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

Synthesis and crystallization of configurable TiO2 nanostructures through anodization process of moderate concentration of NH4F-based organic electrolyte

Materials Research Express
TiO _2 nanostructures play a crucial role in various applications, and optimizing their synthesis is essential for tailoring their properties. Herein, we report the anodization of Ti foils using an electrolyte with a mid-high NH _4 F concentration to ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Multiple Roles for UV RESISTANCE LOCUS 8 in Regulating Gene Expression and Metabolite Accumulation in Arabidopsis under Solar UV Radiation

, 2013
Photomorphogenic responses triggered by low fluence rates of ultraviolet-B radiation (UV-B, 280-315 nm) are mediated by the UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8).

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Involvement of the eIF2α Kinase GCN2 in UV-B Responses

Frontiers in Plant Science, 2019
GCN2 (general control nonrepressed 2) is a serine/threonine-protein kinase that regulates translation in response to stressors such as amino acid and purin deprivation, cold shock, wounding, cadmium, and UV-C exposure. Activated GCN2 phosphorylates the α-
