MTDH antisense oligonucleotides reshape the immunosuppressive tumor microenvironment to sensitize Hepatocellular Carcinoma to immune checkpoint blockade therapy.

Immune checkpoint blockade (ICB) therapy is an important treatment option for individuals with cancer, but it has certain limitations. Identifying a better target that can overcome tumor immune escape and stimulate T cell activity is critical. This research aimed to delve into the molecular mechanism underlying the immunoregulatory function of metadherin (MTDH), which is a novel and potential therapeutic target in hepatocellular cancer (HCC).

Differential roles of NR2A and NR2B subtypes in NMDA receptor-dependent protein synthesis in dendrites.

Protein synthesis in dendrites is critical for long-term synaptic plasticity. Previous studies have identified an essential role of NMDA receptors in control of activity-dependent dendritic protein synthesis, but the contribution of NR2A- and NR2B-containing NMDA receptors, the two predominant subtypes of NMDA receptors in the forebrain, has not been determined. Using a pharmacological approach, we investigated the role of NR2A and NR2B subtypes in the regulation of NMDA-induced dendritic translation of a GFP reporter mRNA controlled by CaMKII untranslated regions (UTRs).

Mitogen-activated protein kinase signaling is essential for activity-dependent dendritic protein synthesis.

The expression of long-lasting synaptic plasticity requires synthesis of new proteins. A critical locus for protein synthesis to support synaptic plasticity is the dendrites. Previous studies demonstrate that synaptic activity activates dendritic protein synthesis.

Molecular network and chromosomal clustering of genes involved in synaptic plasticity in the hippocampus.

Gene transcription is required for establishing and maintaining the enduring form of long term potentiation (LTP). However, the transcriptome and its associated molecular programs that support LTP are not well understood. The purpose of this study was to identify activity-regulated genes (ARGs) and their molecular pathways that are modulated by LTP induction and to investigate the genomic mechanism for coordinating the transcription of ARGs.

Roles of glutamate receptors and the mammalian target of rapamycin (mTOR) signaling pathway in activity-dependent dendritic protein synthesis in hippocampal neurons.

Local protein synthesis in neuronal dendrites is critical for synaptic plasticity. However, the signaling cascades that couple synaptic activation to dendritic protein synthesis remain elusive. The purpose of this study is to determine the role of glutamate receptors and the mammalian target of rapamycin (mTOR) signaling in regulating dendritic protein synthesis in live neurons.

GADD45gamma, down-regulated in 65% hepatocellular carcinoma (HCC) from 23 chinese patients, inhibits cell growth and induces cell cycle G2/M arrest for hepatoma Hep-G2 cell lines.

Growth-arrest and DNA-damage inducible (GADD) genes and Myeloid differentiation primary response (MyD) genes represent a family of genes that play a key role in negative control of cell growth. In the present study, following clone and location of human GADD45 gamma (MyDL) gene, we have found that its mRNA expression level was down-regulated in 15/23 cases of clinic hepatocellular carcinoma (HCC) by comparing the northern hybridization results between the tumor tissues and adjacent normal tissues. Transient transfection of GADD45 gamma cDNA with intact open reading frame sequence into the human hepatoma cells Hep-G2 resulted in dramatic growth suppression in colony formation assays.

Molecular cloning, genomic organization, and mapping of beta 4GalT-VIb, a brain abundant member of beta 4-galactosyltransferase gene family, to human chromosome 18q12.1.

In the present study, a brain abundant member of beta 4-galactosyltransferase gene family with an open reading frame encoding 343 amino acids was cloned and identified from a human leukemia cell cDNA library. The putative protein sequence is about 94.8 and 94.
