CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Efficacy of Hexanal Field Spray on the Postharvest Life and Quality of Papaya Fruit (Carica papaya L.) in Kenya

open access: yesAdvances in Agriculture, 2022
Papaya is a thin-skinned fruit that ripens and softens over a very short time, usually in 3 days, predisposing the fruit to physical damage and phyto-pathogen invasion even with careful handling further shortening postharvest shelf life. The objective of

Ecological Intensification for Crop Protection

open access: yes, 2014
We need to break away from intensive agriculture based on non-renewable and toxic inputs . Safer practices are indeed emerging. Sustainable agriculture started about 50 years ago with the design of integrated pest management (IPM) to counteract pesticide misuse and abuse. Ecological intensification emerged only a few years ago.

Insights into a long life without cancer: The case of the bowhead whale

open access: yesMolecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

open access: yesFEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Oleaginous crops as integrated production platforms for food, feed, fuel and renewable industrial feedstock

open access: yesOilseeds and fats, crops and lipids, 2014
The world faces considerable challenges including how to produce more biomass for food, feed, fuel and industrial feedstock without significantly impacting on our environment or increasing our consumption of limited resources such as water or petroleum ...

Characterization of entomotoxic and nematotoxic genes from indigenous Bacillus thuringiensis strains and their biocontrol potential

open access: yesEgyptian Journal of Biological Pest Control, 2023
Background The gram pod borer (Helicoverpa armigera Hubner), Bihar hairy caterpillar (Spilosoma obliqua Walker), tobacco caterpillar (Spodoptera litura Fabricius) and root knot nematode (Meloidogyne incognita (Kofoid and White) Chitwood) are the major ...

Crop protection in organic agriculture - a simple matter? [PDF]

open access: yes, 2002
This report was presented at the UK Organic Research 2002 Conference. Crop protection strategies in organic agriculture and horticulture aim to prevent pest, disease and weed problems through optimisation of the cropping system as a whole.

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

open access: yesFEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

Development of accessible and scalable maize pollen storage technology

open access: yesCommunications Biology
The inherent short lifespan of Zea mays (maize, corn) pollen hinders crop improvement and challenges the hybrid seed production required to produce food, fuel, and feed.
