Canonical Wnt/β-catenin signaling activation in soft-tissue sarcomas: A comparative study of synovial sarcoma and leiomyosarcoma

open access: yesRare Tumors, 2018
Background: Previous studies have shown that aberrant activation of the Wnt/β-catenin pathway is associated with many malignant neoplasms. This includes some soft-tissue sarcoma phenotypes, most notably synovial sarcoma, implicating potential targets for

Synthesis and Turnover of Mitochondrial Ribonucleic Acid in HeLa Cells: the Mature Ribosomal and Messenger Ribonucleic Acid Species Are Metabolically Unstable [PDF]

open access: yes, 1981
The synthesis rates and half-lives of the individual mitochondrial ribosomal ribonucleic acid (RNA) and polyadenylic acid-containing RNA species in HeLa cells have been determined by analyzing their kinetics of labeling with [5-^3H]-uridine and the ...

Dopamine D1 Receptor Contributes to Glucocorticoid‐Associated Osteonecrosis of Femoral Head Protection Through the ATF3/CHOP Axis to Inhibit Osteoblastic Apoptosis

open access: yesAdvanced Science, EarlyView.
This work identifies a novel mechanism by which dopamine D1 receptor (DRD1) contributes to the pathogenesis of glucocorticoid (GC)‐associated osteonecrosis of the femoral head (ONFH) through the regulation of osteoblastic apoptosis, indicating that DRD1 serves as a critical mediator of the crosstalk between the nervous and skeletal systems.

Chromatin measurements reveal contributions of synthesis and decay to steady‐state mRNA levels

open access: yesMolecular Systems Biology, 2012
Messenger RNA levels in eukaryotes are controlled by multiple consecutive regulatory processes, which can be classified into two layers: primary transcriptional regulation at the chromosomal level and secondary, co‐ and post‐transcriptional regulation of

Clinical Features, Molecular Biology, and the Metastatic Microenvironment in Lung Cancer Brain Metastases: Implications for Treatment Decisions

open access: yesAdvanced Science, EarlyView.
Brain metastases (BM) from lung cancer are aggressive with poor prognosis. This review covers clinical features, diagnosis, early metastasis, and multi‐omics‐elucidated mechanisms, especially the tumor microenvironment of lung cancer with BM. It also discusses preclinical models, signaling pathways, and emerging therapies.

Decoding bioactive signals of the RNA secretome: the cell-free messenger RNA catalogue

open access: yesExpert Reviews in Molecular Medicine
Despite gene-expression profiling being one of the most common methods to evaluate molecular dysregulation in tissues, the utilization of cell-free messenger RNA (cf-mRNA) as a blood-based non-invasive biomarker analyte has been limited compared to other

TaPPR13, a Pentatricopeptide Repeat Protein Gene Activated by TaBZR2, Confers Drought Stress Tolerance by Enhancing the Antioxidant Defense System and Promoting Retrograde Signaling in Wheat (Triticum aestivum)

open access: yesAdvanced Science, EarlyView.
TaPPR13, a PPR protein family gene in wheat is activated by TaBZR2 to enhance drought stress tolerance and photosynthetic capacity. It achieves this by interacting with TaAOR1 and TaSIG5 to improve antioxidant defense and regulate chloroplast gene expression. Abstract The wheat (Triticum aestivum) brassinazole‐resistant 2 (TaBZR2) gene is identified as

FOXQ1 Regulates Brain Endothelial Mitochondrial Function by Orchestrating Calcium Signaling and Cristae Morphology

open access: yesAdvanced Science, EarlyView.
FOXQ1 emerges as a master transcriptional regulator of brain endothelial metabolism, orchestrating mitochondrial function through dual control of calcium signaling and cristae organization. This study reveals that brain endothelial cells rely on oxidative phosphorylation rather than glycolysis alone, challenging the current metabolic paradigm and ...

Nutritional Modulation of Leptin Messenger RNA in Broiler Chickens

open access: yesThe Journal of Poultry Science, 2003
Three sets of experiments were conducted to investigate the nutritional modulation of leptin mRNA expression in chicken adipose tissue and liver. Chicken leptin expression in adipose tissue and liver decreased following 24 h starvation, and gradually ...

NPR1 Promotes Lipid Droplet Lipolysis to Enhance Mitochondrial Oxidative Phosphorylation and Fuel Gastric Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
NPR1 induces lipolysis of stored lipid droplet and enhances mitochondrial oxidative phosphorylation to fuel gastric cancer metastasis. Specifically, NPR1‐mediated activation of PKG directly phosphorylates and activates HSL at Ser855 and Ser951, thereby driving lipolytic processes.
