ORP5 promotes cardiac hypertrophy by regulating the activation of mTORC1 on lysosome.

Introduction: Oxysterol binding protein (OSBP)-related protein 5 (ORP5) mainly functions as a lipid transfer protein at membrane contact sites (MCS). ORP5 facilitates cell proliferation through the activation of mTORC1 signaling. While the pro-hypertrophic effects of mTORC1 are well-documented, the specific role of ORP5 in the context of pathological cardiac hypertrophy remains inadequately understood.

Subcellular mass spectrometric detection unveils hyperglycemic memory in the diabetic heart.

Background: Intensive glycemic control is insufficient to reduce the risk of heart failure in patients with diabetes mellitus. While the hyperglycemic memory in the diabetic cardiomyopathy has been well documented, its underlying mechanisms are not fully understood. The present study tried to investigate whether the dysregulated proteins/biological pathways, which persistently altered in diabetic hearts during normoglycemia, participate in the hyperglycemic memory.

Preliminary exploration of the C-3 galloyl group and the B-5' hydroxyl group enhance the biological activity of catechins in alleviating obesity induced by high-fat diet in mice.

Catechins, among the most active components in tea, effectively alleviate obesity. Catechins are primarily classified into four types based on the presence or absence of the C-3 galloyl group and the B-5' hydroxyl group. However, the impact of conformation on the anti-obesity properties of catechins remains unclear.

Inhibitory Effect and Mechanism of Epigallocatechin Gallate on the Differentiation of 3T3-L1 Preadipocytes.

Green tea possesses a range of beneficial effects, including anti-obesity, antioxidant, and anti-inflammatory properties, owing to its biologically active components, primarily catechins such as epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC), and epigallocatechin gallate (EGCG). However, few studies have investigated the four catechin monomers simultaneously, and the molecular mechanisms of their anti-obesity effects have not been fully elucidated. In this study, we investigated the effects of four catechin monomers on the differentiation of 3T3-L1 preadipocytes of mice.

Engineered mouse H1 promoter mutants with superior RNA polymerase III activity.

Vectors incorporating the human H1 (hH1) promoter are being applied for RNA interference (RNAi) experiments and genome editing. Although extensive studies have been conducted on the hH1 promoter, our understanding of the mouse H1 promoter remains limited. In this study, we predicted the 163 bp mouse H1 (mH1) promoter and 84 bp mouse H1 core (mH1 core) promoter through global alignment and detected its RNA polymerase II (Pol II) and III activities through the expression of the EGFP and the abundance of artificial sequence, which were generally slightly weaker than those of the hH1 promoter.

Adaptive Fuzzy Integral Sliding Mode Cooperative Control Based on Time-Delay Estimation for Free-Floating Close-Chain Manipulators.

Space manipulators are expected to perform more challenging missions in on-orbit service (OOS) systems, but there are some unique characteristics that are not found on ground-based robots, such as dynamic coupling between space bases and manipulators, limited fuel supply, and working with unfixed bases. This paper focuses on trajectory-tracking control and internal force control for free-floating close-chain manipulators. First, the kinematics and dynamics of free-floating close-chain manipulators are given using the momentum conservation and spatial operator algebra (SOA) methodologies, respectively.

The HD-Zip I transcription factor MdHB-7 negatively regulates resistance to Glomerella leaf spot in apple.

Glomerella leaf spot (GLS), caused by Colletotrichum fructicola (Cf), has been one of the main fungal diseases afflicting apple-producing areas across the world for many years, and it has led to substantial reductions in apple output and quality. HD-Zip transcription factors have been identified in several species, and they are involved in the immune response of plants to various types of biotic stress. In this study, inoculation of MdHB-7 overexpressing (MdHB-7-OE) and interference (MdHB-7-RNAi) transgenic plants with Cf revealed that MdHB-7, which encodes an HD-Zip transcription factor, adversely affects GLS resistance.

LncRNA DCRT Protects Against Dilated Cardiomyopathy by Preventing NDUFS2 Alternative Splicing by Binding to PTBP1.

Background: Dilated cardiomyopathy is characterized by left ventricular dilation and continuous systolic dysfunction. Mitochondrial impairment is critical in dilated cardiomyopathy; however, the underlying mechanisms remain unclear. Here, we explored the cardioprotective role of a heart-enriched long noncoding RNA, the dilated cardiomyopathy repressive transcript (DCRT), in maintaining mitochondrial function.

Tryptophan regulates sorghum root growth and enhances low nitrogen tolerance.

Over evolutionary time, plants have developed sophisticated regulatory mechanisms to adapt to fluctuating nitrogen (N) environments, ensuring that their growth is balanced with their responses to N stress. This study explored the potential of L-tryptophan (Trp) in regulating sorghum root growth under conditions of N limitation. Here, two distinct sorghum genotypes (low-N tolerance 398B and low-N sensitive CS3541) were utilized for investigating effect of low-N stress on root morphology and conducting a comparative transcriptomics analysis.

Magnetosheath jets at Jupiter and across the solar system.

The study of jets in the Earth's magnetosheath has been a subject of extensive investigation for over a decade due to their profound impact on the geomagnetic environment and their close connection with shock dynamics. While the variability of the solar wind and its interaction with Earth's magnetosphere provide valuable insights into jets across a range of parameters, a broader parameter space can be explored by examining the magnetosheath of other planets. Here we report the existence of anti-sunward and sunward jets in the Jovian magnetosheath and show their close association with magnetic discontinuities.
