Nanocarriers may carry new hope for brain cancer therapy

A new family of nanocarriers, called '3HM,' has been developed and meets all the size and stability requirements for effectively delivering therapeutic drugs to the brain for the treatment of a deadly form of cancer known as glioblastoma multiforme.

Publication date: January 2019Source: Biomedicine &Pharmacotherapy, Volume 109Author(s): Xin Zhang, Kaikai Ding, Jian Wang, Xingang Li, Peng ZhaoAbstractGlioblastoma multiforme (GBM) is the most common and aggressive primary human brain tumor. Although comprehensive therapies combining radiotherapy and chemotherapy after surgery can prolong survival, the prognosis is still poor with a median survival of only 14.6 months. Chemoresistance is one of the major causes of relapse as well as poor survival in glioma patients. Therefore, novel strategies to overcome chemoresistance are desperately needed for improved treatment ...

Membrane type ‐1 matrix (MT1‐MMP) metalloproteinase is highly expressed in glioblastoma. Inducing cancer cell autophagy may contribute to cancer therapy. We found that ARP101 exploits MT1‐MMP's signal transducing functions to trigger autophagy in a highly invasive glioblastoma cell line model. ARP101 may be envisioned in future therapy modalities against brain cancer. AbstractMembrane type ‐1 matrix metalloproteinase (MT1‐MMP) possesses both extracellular proteolytic and intracellular signal‐transducing functions in tumorigenesis. An imbalance in MT1‐MMP expression and/or function triggers a metastatic, invas...

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.

AbstractCraniotomy surgical site infections are an inherent risk and dreaded complication for the elective brain tumor patient. Sequelae can include delays in resumption in adjuvant treatments for multiple surgeries if staged cranioplasty is pursued. Here, the authors review their experience in operative debridement of surgical site infections with single-stage reimplantation of the salvaged craniotomy bone flap. A prospectively maintained database of a single surgeon ’s neuro-oncology patients from 2009 to 2017 (JRF) was queried to identify 11 patients with surgical site infection after craniotomy for tumor resectio...

Abstract BACKGROUND: Cardiovascular disease (CVD) and cancer are major causes of death in Japan. As most CVDs are chronic and often aggravate, long-term follow-up is necessary. Although some cancer patients and survivors have CVD, its prognostic significance and prevalence are unknown. Therefore, we conducted a retrospective study at our center to determine the prevalence of cancer patients with CVD. METHODS: In 2015, our 10-year (2005-2014) cancer registry was summarized. Comorbidities including left ventricular dysfunction, atrial fibrillation (AF), ischemic heart disease, aortic stenosis, venous thromboemb...

A major limitation of targeted cancer therapy is the rapid emergence of drug resistance, which often arises through mutations at or downstream of the drug target or through intrinsic resistance of subpopulations of tumor cells. Medulloblastoma (MB), the most common pediatric brain tumor, is no exception, and MBs that are driven by sonic hedgehog (SHH) signaling are particularly aggressive and drug-resistant. To find new drug targets and therapeutics for MB that may be less susceptible to common resistance mechanisms, we used a developmental phosphoproteomics approach in murine granule neuron precursors (GNPs), the developm...

Abstract Sorcin (Soluble resistance related calcium binding protein) is a small soluble penta EF family (PEF) of calcium (Ca2+) binding protein (22,000 Da). It has been reported to play crucial roles in the regulation of calcium homeostasis, apoptosis, vesicle trafficking, cancer development, and multidrug resistance (MDR). Overexpression of sorcin has been reported to be associated with different cancers such as breast cancer, colorectal cancer, gastric cancer, leukemia, lung cancer, nasopharyngeal cancer, ovarian cancer, etc. Essentially, expression of sorcin has been found to be elevated in cancer cells as comp...
