A mechanosensitive Ca2+ channel activity is dependent on the developmental regulator DEK1

Nature Communications, 2017
A rise in cytoplasmic Ca2+ concentration is a well-described response of plant cells to mechanical stimulation. Here the authors show that the DEK1 protein, which is essential for epidermis specification and development in plants, is required for ...

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

See the world from a plant’s perspective: on creating an interactive multimedia sculpture implying plant optics

Humanities & Social Sciences Communications
Humans constantly interact with their environment, with other humans, as well as natural and artificial non-human agents. Nevertheless, our somatosensory system limits the diversity of our ways of communicating.

Cell wall modification contributed to high aluminum retention in root epidermis for red skin root syndrome in Panax ginseng

Ecotoxicology and Environmental Safety
Panax ginseng (ginseng) is an important herbal medicine plant; however, successive ginseng cultivation causes intense acidification and active aluminum (Al) dissolution in ginseng bed soil. High Al retention in the root epidermis has been well documented

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Analysis of the impact of latitude on the structure and composition of tea leaves and associated cold resistance

Food Chemistry Advances
In this study, we selected three tea (Camellia sinensis) varieties (Lucha 1, HuangJincha 2, Xueyacha 100). Lucha 1 exhibited the highest levels of sugars suggesting a link between the levels of these three sugars and cold resistance.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
