Targeting the Potassium Channel Kv1.3 Kills Glioblastoma Cells.

CONCLUSION: These data serve as proof of principle that Kv1.3 inhibitors kills GBM cells, but drugs that act in vivo against glioblastoma must be developed to translate these findings in vivo. PMID: 28869943 [PubMed - as supplied by publisher]

The model encompasses the role of cell migration and adhesion, the influence of the extracellular matrix, the effects of oxygen and nutrient availability, and the signalling triggered by chemical cues and growth factors. The proposed in silico hybrid modelling framework combines successful...

AbstractCancer predisposition syndromes are associated with an increased risk of developing primary malignancies. Here we discuss those which are associated with an increased risk of tumors of the central nervous system (CNS) and gastrointestinal (GI) tract. These can be grouped into those in which the CNS tumors predominate versus those in which the GI cancers predominate. The former include constitutional mismatch repair deficiency (CMMRD) syndrome, Li –Fraumeni syndrome (LFS), and Cowden syndrome (CS) while the latter include familial adenomatosis polyposis 1 (FAP1), Lynch syndrome and polymerase proofreading-asso...

Abstract Glioma is the most common type of primary brain tumor, and it has a high mortality rate. Currently, there are only a few therapeutic approaches for gliomas, and their effects are unsatisfactory. Therefore, uncovering the pathogenesis and exploring more therapeutic strategies for the treatment of gliomas are urgently needed to overcome the ongoing challenges. Cellular redox imbalance has been shown to be associated with the initiation and progression of gliomas. Among reactive oxygen species (ROS), hydrogen peroxide (H2O2) is considered the most suitable for redox signaling and is a potential candidate as ...

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,...

Abstract Brain tumors, particularly high-grade glioblastomas, are a crucial public health issue due to poor prognosis and an extremely low survival rate. The glioblastoma multiforme (GBM) grows rapidly within its unique microenvironment that is characterized by active neural communications. Therefore, diverse neurotransmitters not only maintain normal brain functions but also influence glioma progression. To fully appreciate the relationship between neurotransmitters and glioma progression, we reviewed potential neurotransmitter contributors in human GBM and the much less aggressive Low-grade glioma (LGG) by combi...

CONCLUSION: VUGX01 can effectively block proliferation and induce apoptosis of certain type of cancer cells, even it's predicted by high LASSO score, but it is not an effective RTKs inhibitor, it may inhibit cell growth through acting as a novel ligand to one or several GPCRs.

CONCLUSIONS: GDC-0084 demonstrated classic PI3K/mTOR-inhibitor related toxicities. FDG-PET and concentration data from brain tumor tissue suggest that GDC-0084 crossed the blood-brain barrier. PMID: 31937616 [PubMed - as supplied by publisher]

In this study, we report for the first time the incorporation and administration of Aluminum phthalocyanine chloride (AlClPc)-loaded whey protein drug delivery system (AlClPc-PDDS) for the treatment of glioblastoma brain cancer. This system was designed and optimized (with the use of the spray drying technique) to obtain the required particle size (in the range of 100 to 300 nm), zeta potential and drug loading. Our results suggest that we have developed a drug delivery system from a low-cost raw material and preparation method that is capable of incorporating hydrophobic drugs which, in combination with irradiation, ...

ville Malignant gliomas are one of the deadliest forms of brain cancer and despite advancements in treatment, patient prognosis remains poor, with an average survival of 15 months. Treatment using conventional chemotherapy does not deliver the required drug dose to the tumour site, owing to insufficient blood brain barrier (BBB) penetration, especially by hydrophilic drugs. Additionally, low molecular weight drugs cannot achieve specific accumulation in cancerous tissues and are characterized by a short circulation half-life. Nanoparticles can be designed to cross the BBB and deliver their drugs within the brain, thus ...
