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

open access: yesMolecular 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

Two years of nitrogen and sulfur fertilizations in a signal grass pasture under degradation: changes in the root system Adubações com nitrogênio e enxofre durante dois anos em pastagem de capim-braquiária em degradação: alterações no sistema radicular

open access: yesRevista Brasileira de Zootecnia, 2011
The objective of this research was to evaluate the effect of combinations of nitrogen and sulfur rates in degraded signal grass (Brachiaria decumbens) pasture on their productive, morphological and nutritional attributes in the root system at four soil ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Doses e fontes de nitrogênio na recuperação de pastagens do capim-marandu Nitrogen doses and sources on pasture recuperation of grass marandu

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Avaliaram-se o efeito de doses e fontes de nitrogênio na recuperação do capim-marandu, por um período de três anos, em pastagem estabelecida há mais de 10 anos, com baixa produção de forragem. O delineamento experimental foi em blocos completos ao acaso,

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Microradiographical Determination of the Dry Mass Density in the Rat Retina

open access: yesOphthalmic Research, 2009
A method for the quantitative measurement of the dry mass density in retinal tissue is presented. Cryosections of rat retinas were freeze-dried and exposed to soft X-rays together with a reference system. The section thickness was measured optically. The X-ray energy absorbed by the retinal tissue was recorded photographically and the microradiographs ...

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

open access: yesFEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Phosphorus behavior on an Oxisol fertilized by phosphate alkaline biosolid and cultivated with common bean Comportamento do fósforo em Latossolo fertilizado com biossólido alcalinizado fosfatado e cultivado com feijoeiro

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2012
This study aimed to evaluate the extractable phosphorus Mehlich-1 in a distrophic Red-Yellow Latosol (Oxisol) which received alkaline sewage sludge (alkaline biosolid) along with 0, 0.436, 0.872 and 1.745 dag kg-1 of P from three different sources and ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.
