3D models are increasingly used to study mechanisms driving tumor progression and mimicking processes such as invasion and migration. However, there is a need to establish more protocols based on 3D culture systems that allow for downstream molecular biology investigations. Here we present a method for optimal RNA extraction from highly aggressive primary glioma cells invading into Matrigel. The method has been established by comparing previously reported protocols, available commercial kits and optimizing specific steps for matrix dissociation, RNA separation and purification. The protocol allows RNA extraction from cells embedded into Matrigel, with optimal yield, purity and integrity suitable for subsequent sequencing analysis of both high and low molecular weight RNA.

Severe acute respiratory syndrome coronavirus-1 (SARS-CoV-1) and -2 (SARS-CoV-2) are beta-coronaviruses (β-CoVs) that have caused significant morbidity and mortality worldwide. Therefore, a better understanding of host responses to β-CoVs would provide insights into the pathogenesis of these viruses to identify potential targets for medical countermeasures. In this study, our objective is to use a systems biology approach to explore the magnitude and scope of innate immune responses triggered by SARS-CoV-1 and -2 infection over time in pathologically relevant human lung epithelial cells (Calu-3/2B4 cells).

Background: Acute Lymphoblastic Leukemia (ALL) is the most common type of leukemia among children. There are several types of drugs that are common in treating and controlling leukemia, including 6-M. Moreover, the anti-cancer effects of the Thiosemicarbazone-Ni complex were surveyed as well as 6-MP.

Background: Human Lung Carcinoma (LC) is among the most diagnosed cancers across the world among those non-small cell lung cancer (NSCLC) comprises about 85%. Next Generation Sequencing based detection of mutations are now well established in molecular oncology. With the advent of modern diagnostic methods, it is now well known that there are several mutations and gene rearrangements which are associated with the development of LC.

Background: Exogenous Cushing's syndrome, which results from prolonged glucocorticoid treatment, is associated with metabolic abnormalities. Previously, we reported the inhibitory effect of tonsil-derived mesenchymal stem cell conditioned medium (T-MSC CM) on glucocorticoid signal transduction. In this study, we investigated the therapeutic efficacy of T-MSCs in a mouse model of exogenous Cushing's syndrome.
