Fight Aging! Newsletter, August 28th 2017
In conclusion, CAVD is highly prevalent. Long understood as a passive process, it is now known to be complex and one which involves pathophysiological mechanisms similar to those of atherosclerosis. Understanding these mechanisms could help to establish new therapeutic targets that might allow us to halt or at least slow down the progression of the disease. Early Steps in the Tissue Engineering of Intervertebral Discs https://www.fightaging.org/archives/2017/08/early-steps-in-the-tissue-engineering-of-intervertebral-discs/ In this paper, researchers report on progress towards the manufacture of interve...

The 2017 Summer Scholars Working at the SENS Research Foundation
Each year, the SENS Research Foundation accepts a group of young life science academics and puts them to work on projects in aging research, both at the foundation and in allied laboratories, creating ties between research groups that can help to advance the state of the art. This year's batch has worked on a diverse set of projects that spread out beyond core SENS initiatives such as allotopic expression of mitochondrial genes. Reading through their projects is a reminder that a great deal can be accomplished these days given a small team, a little funding, and an equipped laboratory. Progress in medical research is no lo...

Ultrasound to Improve Effectiveness of Cancer Drugs: Interview with Focused Ultrasound Foundation ’s Jessica Foley, PhD
Most people think of ultrasound as an imaging modality. Yet, there are many other clinical uses for the high frequency soundwaves. Focused ultrasound waves can promote the opening of the blood-brain barrier, and they can be used to ablate fibroids, among other uses. Yet the potential of ultrasound in clinical medicine is far from fully realized, as new uses and studies evaluating them are rapidly sprouting, and a particularly interesting one involving checkpoint inhibitors to treat stage IV metastatic breast cancer is about to begin. To get a sense for how ultrasound can improve cancer care in combination with checkpoint i...

Mutant IDH1 and thrombosis in gliomas
Craig M. Horbinski, MD PhDDr. Craig Horbinski ofNorthwestern University and colleagues just published a significant paper inActa Neuropathologica entitledMutant IDH1 and thrombosis in gliomas. Horbinski ' s data suggests that, quoting the abstract, " mutant IDH1 has potent antithrombotic activity within gliomas and throughout the peripheral circulation. These findings have implications for the pathologic evaluation of gliomas, the effect of altered isocitrate metabolism on tumor microenvironment, and risk assessment of glioma patients for venous thromboemboli." It should be noted that this paper won theRubinstein Awar...

CAP16 Abstract Highlights - Astrocytoma With a Distinct Molecular Signature: MYB Rearrangement and EGFR Amplification
We report the first case of a pediatric astrocytoma with both MYB rearrangement and EGFR amplification. A 3-year-old boy was found to have a T2 hyperintense, nonenhancing mass in theleft temporal lobe after minor head trauma. Histology showed a diffuse astrocytic tumor with low cell density and bland cytology. Mitotic figures were present, albeit focally, prompting a diagnosis of anaplastic astrocytoma. No necrosis or microvascular proliferation was identified. The Ki-67 labeling index, while generally low, rose to approximately 20%, corresponding to regions of mitotic activity. Interphase fluorescence in situ hybridizatio...

A 60-year-old man presents with acute confusion, aggressive behavior, and aphasia
T2-weighted FLAIR MRI A 60-year-old man presents with acute confusion, aggressive behavior, and aphasia. Imaging reveals a heterogeneously enhancing mass (5 x 2 x 2 cm) in the left medial temporal lobe with extensive peripheral edema (image above), but no significant contrast enhancement. A subtotal temporal lobectomy was performed on suspicion of a low-grade glioma.High-power view of biopsy from left temporal lobeThe diagnosis is herpes simplex encephalitis. PCR amplification of DNA from the specimen more specifically identified the causative agent as herpes simplex virus, type 1 (HSV1). The most common identifiable ...

Best Post of May 2016 -- MYB-QKI fusion: A novel alteration that may define and drive pediatric angiocentric glioma
The next in our "Best of the Month" series comes from May 12, 2016Angiiocentric gliomaAngiocentric glioma is a rare form of pediatric low-grade gliomas (PLGG), first described in 2005, that arises in the cerebral cortex and shares histological features of astrocytomas and ependymomas. Until now, nothing was known of the genetic events underlying this tumor type. In a recent study published in Nature Genetics, Bhandopadhayay et al (see reference below) used whole genome sequencing and/or RNAseq to show that all seven angiocentric gliomas in their sample set harbored rearrangements in MYB, the most common bein...
