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 ...

Effect of Glutathione, Citronella, and Fluoride Gels on Debonding Force of Ceramic Brackets, Adhesive Remnant Index, and Enamel Surface

The Journal of Contemporary Dental Practice
This study aimed to evaluate the glutathione, fluoride, and citronella gels on reducing the shear bond strength (SBS) of ceramic brackets to facilitate the debonding process and reduce enamel damage and chair time.Eighty extracted human premolar teeth bonded with ceramic brackets were divided equally into four groups according to the type of solvent ...

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.

In vitro Analysis of Shear Bond Strength and Adhesive Remnant Index of Stainless Steel Brackets with Different Adhesive Systems to Enamel.

The journal of contemporary dental practice, 2019
This study aimed at evaluating and comparing the bond strength of stainless steel brackets bonded with multiple orthodontic adhesives.About 60 premolars extracted to create space during orthodontic treatment were included in the present study. Premolar stainless steel brackets of size 0.022" slot with the surface area of bracket base of 11.15 mm2 were ...

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.

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.
