Dielectric properties of epoxy silica and boron nitride nanocomposites and moisture/temperature influences

open access: yesIET Nanodielectrics, 2018
The epoxy resin was filled with nano-BN, surface treated, and untreated nano-SiO(2). Measurements of dielectric spectroscopy cover the range of frequency from 10^−2 to 10^5 Hz and will relate to the hydration of samples.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
