Molecular and radiological characterization of Glioblastoma Multiforme using MRI.

CONCLUSIONS: This study shows that ADC/CE plot can divide GBM into four regions, whose heterogeneity is evidenced by differential expression of nuclear pleomorphism, necrosis, cellularity and mitotic rate as well as the expression of oncogene and stem cell markers.

AbstractTumour progression involves interactions among various cancer cell clones, including the cancer stem cell subpopulation and exogenous cellular components, termed cancer stromal cells. The latter include a plethora of tumour infiltrating immunocompetent cells, among which are also immuno-modulatory mesenchymal stem cells, which by vigorous migration to growing tumours and susequent transdifferentiation into various types of tumour-residing stromal cells, may either inhibit or support tumour progression. In the light of the scarce therapeutic options existing for the most malignant brain tumour glioblastoma, mesenchy...

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...

Abstract Glioma, especially its most malignant type, glioblastoma (GBM), is the most common and the most aggressive malignant tumour in the central nervous system. Currently, we have no specific therapies that can significantly improve its dismal prognosis. Recent studies have reported promising in vitro experimental results of several novel glioma-targeting drugs; these studies are encouraging to both researchers and patients. However, clinical trials have revealed that novel compounds that focus on a single, clear glioma genetic alteration may not achieve a satisfactory outcome or have side effects that are unbe...

It’s only been seven years since scientists first learned how to precisely and reliably splice the human genome using a tool called CRISPR, making it possible to think about snipping out disease-causing mutations and actually cure, once and for all, genetic diseases ranging from sickle cell anemia to certain types of cancer and even blindness. Doctors are plunging ahead in search of ways to use the relatively new technology to start treating patients. In China last November, scientist Jiankui He stunned—and dismayed—the genetic community when he announced he had already used CRISPR, which many believe sti...

In conclusion, with study of the frailty syndrome still in its infancy, frailty analysis remains a major challenge. It is a challenge that needs to be overcome in order to shed light on the multiple mechanisms involved in the pathogenesis of this syndrome. Although several mechanisms contribute to frailty, immune system alteration seems to play a central role: this syndrome is characterized by increased levels of pro-inflammatory markers and the resulting pro-inflammatory status can have negative effects on various organs. Future studies should aim to better clarify the immune system alteration in frailty, and seek to esta...

In this study we show, for the first time, significant alterations in cholesterol efflux capacity in adolescents throughout the range of BMI, a relationship between six circulating adipocyte-derived EVs microRNAs targeting ABCA1 and cholesterol efflux capacity, and in vitro alterations of cholesterol efflux in macrophages exposed to visceral adipose tissue adipocyte-derived EVs acquired from human subjects. These results suggest that adipocyte-derived EVs, and their microRNA content, may play a critical role in the early pathological development of ASCVD.

CONCLUSIONS: CD133 is a marker for medulloblastoma SCLCCs. Both CD133-enriched and CD133-depleted medulloblastoma cell populations demonstrated sensitivity to UAB30, indicating its potential as a therapeutic option for group 3 medulloblastoma. PMID: 31362265 [PubMed - as supplied by publisher]

In this study, we show that oncogenic signalling induces redistribution of EZH2 across the genome, which in turn misregulates key homeotic genes and corrupts the identity of neural cells. Characterisation of EZH2 direct targets in de novo transformed cells reveals that acquisition of tumorigenic potential is accompanied by a transcriptional switch involving de-repression of spinal cord-specifying HOX genes and concomitant silencing of the empty spiracles homologue EMX2, a key regulator of neurogenesis in the forebrain and negative regulator of neural stem cell proliferation. Our results suggest that by redistributing EZH2 ...
