SR-A3 suppresses AKT activation to protect against MAFLD by inhibiting XIAP-mediated PTEN degradation.

Scavenger receptor class A member 3 (SR-A3) is implicated in metabolic diseases; however, the relationship between SR-A3 and metabolic dysfunction-associated fatty liver disease (MAFLD) has not been documented. Here, we show that hepatic SR-A3 expression is significantly reduced in human and animal models in the context of MAFLD. Genetic inhibition of SR-A3 in hamsters elicits hyperlipidemia, hyperglycemia, insulin resistance, and hepatic steatosis under chow-diet condition, yet escalates in diet-induced MAFLD.

Fat-1 Ameliorates Metabolic Dysfunction-Associated Fatty Liver Disease and Atherosclerosis through Promoting the Nuclear Localization of PPARα in Hamsters.

Fat-1, an enzyme encoded by the gene, is responsible for the conversion of endogenous omega-6 polyunsaturated fatty acids into omega-3 polyunsaturated fatty acids in . To better investigate whether the expression of Fat-1 will exert a beneficial function in dyslipidemia and metabolic dysfunction-associated fatty liver disease (MAFLD), we established an adeno-associated virus 9 expressing Fat-1. We found that adeno-associated-virus-mediated expression of Fat-1 markedly reduced the levels of plasma triglycerides and total cholesterol but increased high-density lipoprotein levels in male wild-type hamsters on both chow diet and high-fat diet as well as in chow-diet-fed male LDLR hamsters.

Motor protein KIF13B orchestrates hepatic metabolism to prevent metabolic dysfunction-associated fatty liver disease.

Background: Kinesin family member 13B (KIF13B), a crucial motor protein, exerts multiple cellular biological functions. However, the implication of KIF13B in metabolic dysfunction-associated fatty liver disease (MAFLD) has not been explored yet. This study aimed to investigate KIF13B's role and underlying mechanism in MAFLD and proposes it as a potential pharmacological target.

Thrombocytopenia is associated with increased risks of severe disease progression and mortality. Antiviral agents have shown much promise in decreasing viral load and shortening the time to the resolution of symptoms.

The cell cycle oscillator and spindle length set the speed of chromosome separation in Drosophila embryos.

Anaphase is tightly controlled spatiotemporally to ensure proper separation of chromosomes. The mitotic spindle, the self-organized microtubule structure driving chromosome segregation, scales in size with the available cytoplasm. Yet, the relationship between spindle size and chromosome movement remains poorly understood.

Enrichment of carcinoembryonic antigen by epitope molecularly imprinted polymer based on cucurbituril host-guest interaction.

Carcinoembryonic antigen (CEA) is a common tumor marker used to diagnose diseases. However, the use of molecularly imprinted polymer with whole proteins as templates or antibodies to identify and isolate CEA presents issues such as high prices and difficult removal of templates. Here, due to the specific binding of cucurbit[7]uril (CB[7]) to N-terminal phenylalanine, we prepared a novel oriented epitope molecularly imprinting polymer based on host-guest interaction (hg-MIP) for the identification and separation of CEA.

Neuromorphic Nanofluidic Sense Digitalization.

Nanofluidic memristors have recently been reshaped into artificial synapses capable of mimicking many fundamental neurosynaptic patterns, while sense digitalization has been increasingly explored to link the neuromorphic devices with external equipment. By inspiration of dopaminergic nerve, here a nanofluidic nerve with sense digitalization is devised by engineering a dopamine (DA)-specific nanofluidic synapse as mediated by PC-12 cells to manage the robotic arm. Different from previous neuromorphic perception of DA via redox reaction, the aptamer-based perception here is based on biological DA recognition by its receptor as indicated by the ionic signals.

Retroperitoneal bronchogenic cyst: a case report and literature review.

Introduction: Retroperitoneal bronchogenic cyst, typically situated in the subdiaphragmatic region, is a rare congenital benign developmental abnormality arising from dysplasia of the foregut and abnormal budding of the tracheobronchial tree. Due to its low incidence, there are limited reports regarding this condition.

Case Presentation: Four retroperitoneal bronchogenic cysts near the left adrenal gland were identified without accompanying clinical symptoms.

Tetraspanin 3 promotes NSCLC cell proliferation via regulation of β1 integrin intracellular recycling.

Background: The involvement of tetraspanins in cancer development has been widely implicated. In this study, the function and molecular mechanisms of tetraspanin 3 (TSPAN3) in non-small cell lung cancer (NSCLC) cells were explored.

Methods: Tissue samples from patients diagnosed with NSCLC were analyzed by immunohistochemistry, western blotting, and real-time polymerase chain reaction (PCR) to indicate the involvement of TSPAN3 in cancer progression.

Metal-Organic Framework Nanofluidic Synapse.

Chemical synapse completes the signaling through neurotransmitter-mediated ion flux, the emulation of which has been a long-standing obstacle in neuromorphic exploration. Here, we report metal-organic framework (MOF) nanofluidic synapses in which conjugated MOFs with abundant ionic storage sites underlie the ionic hysteresis and simultaneously serve as catalase mimetics that sensitively respond to neurotransmitter glutamate (Glu). Various neurosynaptic patterns with adaptable weights are realized via Glu-mediated chemical/ionic coupling.

BRCA1-associated-protein-1 inactivated melanocytic tumours: characterisation of the clinicopathological spectrum and immunohistochemical expression pattern of preferentially expressed antigen in melanoma.

Aims: BRCA1-associaed protein-1 (BAP1) inactivated tumours (BIMT) are rare melanocytic tumours that may be mistaken for Spitz tumours or melanoma. They occur sporadically or in association with the BAP1 tumour predisposition syndrome (BAP1-TPDS), which may be complicated by uveal or cutaneous melanoma, mesothelioma, basal cell carcinoma and renal cell carcinoma. The aim of this study was to characterise the clinicopathological features and the immunohistochemical expression pattern of preferentially expressed antigen in melanoma (PRAME) of BIMT in a large patient cohort.

Platelet-derived TGF-β1 induces functional reprogramming of myeloid-derived suppressor cells in immune thrombocytopenia.

Platelet α-granules are rich in transforming growth factor β1 (TGF-β1), which is associated with myeloid-derived suppressor cell (MDSC) biology. Responders to thrombopoietin receptor agonists (TPO-RAs) revealed a parallel increase in the number of both platelets and MDSCs. Here, anti-CD61 immune-sensitized splenocytes were transferred into severe combined immunodeficient mice to establish an active murine model of immune thrombocytopenia (ITP).

Robust cytoplasmic partitioning by solving an intrinsic cytoskeletal instability.

Early development across vertebrates and insects critically relies on robustly reorganizing the cytoplasm of fertilized eggs into individualized cells. This intricate process is orchestrated by large microtubule structures that traverse the embryo, partitioning the cytoplasm into physically distinct and stable compartments. Despite the robustness of embryonic development, here we uncover an intrinsic instability in cytoplasmic partitioning driven by the microtubule cytoskeleton.
