Integrating Proteomics and Transcriptomics Reveals the Potential Pathways of Hippocampal Neuron Apoptosis in Dravet Syndrome Model Mice.

An important component contributing to the onset of epilepsy is the death of hippocampal neurons. Several studies have shown that Dravet syndrome model mice: KO mice have a high number of apoptotic neurons following seizures, but the precise mechanism underlying this remains unclear. The aim of this research was to elucidate the potential molecular mechanism of neuronal apoptosis in KO mice by integrating proteomics and transcriptomics, with the ultimate goal of offering better neuroprotection.

Discovery and characterization of the novel conotoxin Lv1d from Conus lividus that presents analgesic activity.

Cone snails are predatory gastropod mollusks that are distributed in all tropical marine environments and contain small peptides (conotoxins) in their venom to capture prey. However, the biochemical and molecular aspects of conotoxins remain poorly understood. In this article, a novel α4/7-conotoxin, Lv1d, was obtained from the venom duct cDNA library of the worm-hunting Conus lividus collected from the South China Sea.

HSP60 participates in the anti-glioma effects of curcumin.

The chaperone protein heat shock protein 60 (HSP60) is considered a tumor promoter in several types of primary human tumors, where it orchestrates a broad range of survival programs. Curcumin (CCM) is well-established to exhibit several anticancer properties with an excellent safety profile. Our previous study showed that CCM suppresses extracellular HSP60 expression, which is typically released by activated microglia, and acts as an inflammatory factor by binding to Toll-like receptor 4 (TLR-4) on the cell membrane.

Marchantin C: a potential anti-invasion agent in glioma cells.

Cancer cell migration is a leading cause of tumor recurrence and treatment failure. Previously, we reported that marchantin C exhibited promising antitumor activity by inducing microtubule depolymerization and apoptosis. In the present study, we investigated the effect of marchantin C on inhibition of migration in T98G and U87 cells.

JSI-124 inhibits glioblastoma multiforme cell proliferation through G(2)/M cell cycle arrest and apoptosis augment.

JSI-124 (cucurbitacin I) is a selective inhibitor of Janus kinase/signal transducer and activator of transcription 3(JAK/STAT3) and has been shown to exert anti-proliferative and anti-tumor properties both in vitro and in vivo. As STAT3 activation has been implicated in the development of glioma, we investigated the therapeutic efficacy of JSI-124 on glioblastoma multiforme (GBM) by interfering with STAT3 pathway. In present study, two GBM cell lines, U251 and A172 cells, were treated with JSI-124.

Blockage of the STAT3 signaling pathway with a decoy oligonucleotide suppresses growth of human malignant glioma cells.

Gliomas are the most common type of primary tumor in the human central nervous system. STAT3, a signal transducer and activator of transcription 3, is over expressed in gliomas. Its involvement in tumorgenesis can be attributed to its ability to induce cell proliferation and inhibit apoptosis.

Dendritic cell-based immunotherapy for malignant glioma.

The immunotherapy for malignant glioma faces unique difficult, due to some anatomical and immunological characteristics including the existence of blood brain barrier, the absence of lymphatic tissues and dendritic cells (DCs) in the central nervous system (CNS) parenchyma, and the presence of an immunosuppressive microenvironment. Therefore, immunotherapeutic approaches will not be beneficial unless the compromised immune status in malignant glioma patients is overcome. DC-based immunotherapy, vaccinating cancer patients with DCs pulsed with various tumor antigens, is one of the most promising immunotherapeutic approaches for treatment of malignant glioma because it seems able to overcome, at least partially, the immunosuppressive state associated with primary malignancies.
