Biomimetic Nano-delivery of Small-Molecule Piceatannol Modulates Tumor Stemness and Suppresses Colorectal Cancer Metastasis via Hippo/YAP1/SOX9 Signaling.

Suppressing tumor metastasis is a crucial strategy for improving survival rates in patients with colorectal cancer (CRC), with cancer stem cells (CSCs) being the primary drivers of metastasis. Current therapeutic approaches targeting CSCs are limited, and their molecular mechanisms remain unclear. To address this challenge, a biomimetic nanoparticle delivery system, CMD-BHQ3-PTL/DOX@RBCM is developed, to deliver the stem cell regulator, piceatannol (PTL).

Bone Marrow Adipose Tissue as a Critical Regulator of Postmenopausal Osteoporosis - A Concise Review.

Postmenopausal osteoporosis (PMOP) is a major health problem affecting millions of women worldwide. PMOP patients are often accompanied by abnormal accumulation of bone marrow adipose tissue (BMAT). BMAT is a critical regulator of bone homeostasis, and an increasing BMAT volume is negatively associated with bone mass reduction or fracture.

Prognostic marker CXCL5 in glioblastoma polyformis and its mechanism of immune invasion.

Glioblastoma multiforme (GBM) is the most aggressive brain cancer with a poor prognosis. Therefore, the correlative molecular markers and molecular mechanisms should be explored to assess the occurrence and treatment of glioma.WB and qPCR assays were used to detect the expression of CXCL5 in human GBM tissues.

Lycium barbarum polysaccharides restore adverse structural remodelling and cardiac contractile dysfunction induced by overexpression of microRNA-1.

MicroRNA-1 (miR-1) stands out as the most prominent microRNA (miRNA) in regulating cardiac function and has been perceived as a new potential therapeutic target. Lycium barbarum polysaccharides (LBPs) are major active constituents of the traditional Chinese medicine based on L. barbarum.

Long-Term Administration of Neuropeptide Y in the Subcutaneous Infusion Results in Cardiac Dysfunction and Hypertrophy in Rats.

Background/aims: The purpose of the present study was to clarify whether chronically elevated plasma neuropeptide Y (NPY) might affect heart function and cardiac remodeling in rats.

Methods: Male Wistar rats were administered NPY (85 μg for 30 days) by mini-osmotic pump subcutaneously implanted between the scapulae. Associated indices for heart function, cardiac remodeling and hypertrophy were evaluated.

MicroRNA-23a participates in estrogen deficiency induced gap junction remodeling of rats by targeting GJA1.

Increased incidence of arrhythmias in women after menopause has been widely documented, which is considered to be related to estrogen (E2) deficiency induced cardiac electrophysiological abnormalities. However, its molecular mechanism remains incompletely clear. In the present study, we found cardiac conduction blockage in post-menopausal rats.

Decorating titanate nanotubes with protonated 1,2,4-triazole moieties for anhydrous proton conduction.

Anhydrous proton conducting materials based on surface attachment of protonated 1,2,4-triazole moieties on titanate nanotubes are prepared through self-assembly technique. (1)H MAS NMR spectra have revealed that the triazole moieties located at the outer surface of nanotubes. The distance between two ionic groups at the surface is observed to be shorter than 1nm, which may facilitate the formation of continuous proton conducting domains, leading to easy proton transport through segmental motion and structural re-organization in the absence of water.

Expression of amyloid-associated miRNAs in both the forebrain cortex and hippocampus of middle-aged rat.

Background: Aging is associated with the gradual cognitive decline and shows the typical senile plaque formation in the brain, which results from the aggregation of beta amyloid (Aβ) peptide following the abnormal proteolytic processing of amyloid precursor protein (APP) by β-secretase (BACE1) and γ-secretase. Accumulating evidence indicates that several microRNAs (miRNAs) are involved in the Alzheimer's disease (AD) by regulating the expression of APP and BACE1 proteins. However, the cognitive ability and the expression profile of the APP- and BACE1-associated miRNAs in the middle-aged population are largely unknown.

Inhibition of peripheral NPY Y1 and Y2 receptors ameliorates the aberrant baroreceptor reflex sensitivity in streptozotocin induced diabetic rats.

Neuropeptide Y (NPY), a sympathetic neurotransmitter, is highly associated with baroreflex dysfunction and multiple cardiac diseases such as diabetic myocardiopathy. In the present study, we aimed to explore the role of peripheral NPY Y1 receptor (Y1R) and Y2 receptor (Y2R), which are dominantly present in peripheral cardiovascular control, in baroreflex sensitivity (BRS) of streptozotocin (STZ)-induced diabetic rats. Peripheral Y1R and Y2R were antagonized by specific antagonists (BIBP 3226 and BIIE 0246, respectively) from subcutaneously implanted ALZET mini-osmotic pump in STZ-induced diabetic rats for 4 weeks.

MicroRNA-195 protects against dementia induced by chronic brain hypoperfusion via its anti-amyloidogenic effect in rats.

Previous studies have demonstrated that chronic brain hypoperfusion (CBH) causes Aβ aggregation by upregulating expression of amyloid precursor protein (APP) and β-site APP cleaving enzyme 1 (BACE1) protein, which is accompanied by cognitive impairment, but the mechanisms are not fully understood. In this study, we evaluated the effect of microRNA on memory impairment in rats induced by CBH. We show here that CBH generated by bilateral common carotid artery occlusion (2VO) significantly decreased the learning and memory ability in rats, as assessed by Morris water maze, and upregulated expression of APP and BACE1 proteins in the hippocampus and cortex of rats, as evaluated by Western blot and immunofluorescence.

Overexpression of microRNA-1 impairs cardiac contractile function by damaging sarcomere assembly.

Aims: The purpose of the present study was to evaluate the effects of overexpression of microRNA-1 (miR-1) on cardiac contractile function and the potential molecular mechanisms.

We found an age-dependent decrease in the heart function in Tg mice by pressure-volume loop analysis.

Neuropeptide Y reverses chronic stress-induced baroreflex hypersensitivity in rats.

Chronic stress, as a risk factor for cardiovascular diseases, has been reported to result in elevated plasma neuropeptide Y (NPY) and be highly associated with abnormal cardiac autonomic function.

Seven types of recognized stressors were used to develop chronic stress rat model.

Daming capsule restores endothelial dysfunction induced by high-fat diet.

Background: Daming capsule (DMC), a traditional Chinese formula, has a lipid-modulating action with reduced adverse side effects as compared with other lipid lowering compounds. Since endothelial dysfunction often accompanies the hyperlipidemic state, we hypothesize that DMC might restore endothelial dysfunction produced by a high-fat (HF) diet. Importantly, we also investigate possible mechanisms involved in mediating the effects of DMC on vascular reactivity.
