GSE143798 Anticancer potential of UDCA on GBM

Contributors : Zhong Yao ; Xingang LiSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensGlioblastoma multiforme (GBM) is the deadliest form of brain tumor with a median survival time of 15 months due to drug resistance. Ursodeoxycholic acid (UDCA) is approved of cancer suppressive potential in several tumors. Here we researched on the antitumor potential of UDCA on GBM. The CCK-8 and colony formation was used for detecting cell viability. RNA sequencing hinted transcriptional profile and pathways. PCR and western blot tested the change of related markers. Phenotype changes as cell cycle, apoptosis, MMP and ROS were measured. UDCA inhibited GBM cell viability in a dose- and time-dependent way. RNA sequencing results exhibited UDCA treatment was related to glioma progression and located on mitochondria and endoplasmic reticulum (ER). Cell cycle was arrested in G1 phase followed by caspase-independent apoptosis. UDCA led to decreased MMP, overproduction of ROS and ER stress. Three main stress sensors ATF6, IRE1 αand PERK were activated in acute phase. Combining UDCA with bortezomib achieved a synergistic effect via enhancing PERK/ATF4/CHOP pathway and alleviating IRE1α activation. UDCA inhibited GBM progression and the combination with bortezomib achieved a synergistic effect via protracted ER stress. UD CA, alone or with combination of BTZ, presented a promising drug for GBM.

Kaloss, Erwin Kristobal Gudenschwager Basso, Michelle H. TheusAbstractPrimary brain tumors are among the deadliest cancers that remain highly incurable. A need exists for new approaches to tumor therapy that can circumvent the blood brain barrier (BBB), target highly resistant tumors and cancer stem-like cells (CSCs) as well create an anti-cancer immunomodulatory environment. Successful treatments may also require a combinatory approach utilizing surgery, chemotherapy, ra...

We examined lncRNA profiles from three glioma specimens using lncRNA expression profiling microarrays. Quantitative real-time RT-PCR was used to analyze the differential expression of raw intensities of lncRNA expression in glioma and peritumoral tissues. Results: We found 4858 lncRNAs to be differentially expressed between tumor tissue and peritumoral tissue. Of these, 2845 lncRNAs were up-regulated (fold change> 3.0) and 2013 were down-regulated (fold change 3.0) and 1804 that were down-regulated (fold change

Conclusions: VEGFA and CXCL8 are important factors for angiogenesis, which are suggested to have significant roles during tumorigenesis. Our results provide further evidence that VEGFA and CXCL8 could induce angiogenesis and promote LGG to progress into GBM. These findings could be useful in developing novel targeted therapeutics approaches in the future.Resumo Os tumores cerebrais s ão uma das causas mais comuns de mortes relacionadas ao câncer em todo o mundo. A angiogênese tem caráter crítico em gliomas malignos de alto grau, como o glioblastoma multiforme. Objetivo: O objetivo deste est...

(Jackson Laboratory) For cancers such as glioma, preclinical research models have failed to provide sufficient insight for medical progress. A team led by Jackson Laboratory's Roel Verhaak thoroughly analyzed sporadic canine gliomas and found that their molecular characteristics, including gene mutations and duplications, resemble those of humans. The results indicate that dogs provide an effective model for human gliomas, and learning how to more effectively treat our pets will likely inform better prognoses for human patients.

Authors: Burnstock G Abstract ATP is a cotransmitter with glutamate, noradrenaline, GABA, acetylcholine and dopamine in the brain. There is a widespread presence of both adenosine (P1) and P2 nucleotide receptors in the brain on both neurons and glial cells. Adenosine receptors play a major role in presynaptic neuromodulation, while P2X ionotropic receptors are involved in fast synaptic transmission and synaptic plasticity. P2Y G protein-coupled receptors are largely involved in presynaptic activities, as well as mediating long-term (trophic) signalling in cell proliferation, differentiation and death during develo...

Authors: Gutmann DH Abstract Brain tumors are complex cellular ecosystems, composed of populations of both neoplastic and non-neoplastic cell types. While the contributions of the cancer cells in low-grade and high-grade gliomas have been extensively studied, there is comparatively less known about the contributions of the non-neoplastic cells in these tumors. As such, a large proportion of the non-neoplastic cells in gliomas are resident brain microglia, infiltrating circulating macrophages, and T lymphocytes. These immune system-like stromal cells are recruited into the evolving tumor through the elaboration of c...

Glioblastoma multiforme (GBM) is one of the most serious types of gliomas. Although considerable progress has been made in the development of cancer therapeutic agents, several antineoplastic drugs fail to penetrate the blood‑brain barrier (BBB), resulting in a low survival rate of glioma ...
