VCP downstream metabolite glycerol-3-phosphate (G3P) inhibits CD8T cells function in the HCC microenvironment.

CD8T cells within the tumor microenvironment (TME) are often functionally impaired, which limits their ability to mount effective anti-tumor responses. However, the molecular mechanisms behind this dysfunction remain incompletely understood. Here, we identified valosin-containing protein (VCP) as a key regulator of CD8T cells suppression in hepatocellular carcinoma (HCC).

A STT3A-dependent PD-L1 glycosylation modification mediated by GMPS drives tumor immune evasion in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a malignant tumor characterized by rapid progression. To explore the regulatory mechanism of rapid tumor growth and metastasis, we conducted proteomic and scRNA-Seq analyses on advanced HCC tissues and identified a significant molecule, guanine monophosphate synthase (GMPS), closely associated with the immune evasion in HCC. We analyzed the immune microenvironment characteristics remodeled by GMPS using scRNA-Seq and found GMPS induced tumor immune evasion in HCC by impairing the tumor-killing function of CD8  T cells.

Exploring the Interplay of Diet, Obesity, Immune Function, and Cancer.

This commentary provides an in-depth exploration of the intricate relationships among diet, obesity, immune function, and cancer, highlighting the potential role of dietary interventions as complementary therapies in cancer treatment. Multiple analyses underscore the importance of personalized dietary strategies in cancer management and identify opportunities for further research in this evolving field.

[Clinical Features and Prognosis of Secondary Intestinal Diffuse Large B-Cell Lymphoma].

Objective: To explore and analyze the clinical features and prognostic factors of secondary intestinal diffuse large B-cell lymphoma (SI-DLBCL), in order to provide reference for the basic research and clinical diagnosis and treatment of secondary lymphoma of rare sites in the field of hematology.

Methods: The clinical data of 138 patients with SI-DLBCL admitted to Fujian Medical University Union Hospital from June 2011 to June 2022 were collected and sorted, the clinical and pathological features, diagnosis, treatment and prognosis were analyzed. Cox regression risk model was used to conduct univariate and multivariate analysis on the prognostic risk factors.

Exploring the role of the immune microenvironment in hepatocellular carcinoma: Implications for immunotherapy and drug resistance.

Hepatocellular carcinoma (HCC), the most common type of liver tumor, is a leading cause of cancer-related deaths, and the incidence of liver cancer is still increasing worldwide. Curative hepatectomy or liver transplantation is only indicated for a small population of patients with early-stage HCC. However, most patients with HCC are not candidates for radical resection due to disease progression, leading to the choice of the conventional tyrosine kinase inhibitor drug sorafenib as first-line treatment.

Printable Graphene Oxide Micropatterns for a Bio-Subretinal Chip.

Recently, implantable artificial subretinal chips using electronic components have replaced photoreceptors to serve as the most feasible treatment for retinal diseases. As such a chip that is meant to be implanted and used for very long periods, growing retinal cells on it to improve the electrical stimulation efficiency and attraction of neuronal elements remains a challenge. Here, an inkjet printing technology is employed to create graphene oxide (GO) micropatterns onto microelectrodes of a photovoltaic-powered implantable retinal chip.

A microfabricated coil for implantable applications of magnetic spinal cord stimulation.

In this paper, a microfabricated inductive coil comprising of 125-turn coil windings and a MnZn-based magnetic core in a volume of 200 mm(3) is presented for the magnetic neural stimulation in a spinal cord. The coil winding with the parallel-linkage design instead of the typical serial-linkage one is proposed not only to provide better design flexibility to the current mode driving circuit but also to simplify the fabrication process of the 3-D inductive coil, which can further advance the coil miniaturization. Experimental results show the microcoil with a 1.
