The central dogma of molecular biology, has remained a cornerstone of classical molecular biology. However, serendipitously discovered microRNAs (miRNAs) in nematodes paradigmatically shifted our current knowledge of the intricate mechanisms during transitions from transcription to translation. The discovery of miRNA captured considerable attention and appreciation, and we had witnessed an explosion in the field of non-coding RNAs. Ground-breaking discoveries in the field of non-coding RNAs have helped in better characterization of microRNAs and long non-coding RNAs (LncRNAs). There is an ever-increasing list of miRNA targets that are regulated by MALAT1 to stimulate or repress the expression of target genes. However, in this review, our main focus is to summarize mechanistic insights on MALAT1-mediated regulation of oncogenic signaling pathways. We have discussed how MALAT1 modulated TGF/SMAD and Hippo pathways in various cancers. We have also comprehensively summarized how JAK/STAT and Wnt/β-catenin pathways stimulated MALAT1 expression and consequentially how MALAT1 potentiated these signaling cascades to promote cancer. MALAT1 research has undergone substantial broadening. However, there is still a need to identify additional mechanisms. MALAT1 is involved in the multi-layered regulation of multiple transduction cascades, and detailed analysis of different pathways will be advantageous in getting a step closer to individualized medicine.The clinical pathology of various human malignancies is supported by tropomyosin receptor kinase (Trk) B TrkB which is a specific binding receptor of the brain-derived neurotrophic factor (BDNF). TrkB and TrkB fusion proteins have been observed to be over-expressed in many cancer patients. Moreover, these proteins have been observed in multiple types of cells. A few signaling pathways can be modulated by the abnormal activation of the BDNF/TrkB pathway. These signaling pathways include PI3K/Akt pathway, transactivation of EGFR, phospholipase C-gamma (PLCγ) pathway, Ras-Raf-MEK-ERK pathway, Jak/STAT pathway, and nuclear factor kappalight- chain-enhancer of activated B cells (NF-kB) pathway. The BDNF/TrkB pathway, when overexpressed in tumors, is correlated with reduced clinical prognosis and short survival time of patients. Targeting the BDNF/TrkB pathway and the use of Trk inhibitors, such as entrectinib, larotrectinib, etc. are promising methods for targeted therapy of tumors. The present review provides an overview of the role of the TrkB pathway in the pathogenesis of cancer and its value as a potential therapeutic target.
This study aims to explore in detail, the mechanism of the carbon monoxide releasing molecule-3 (CORM-3) in regulating the activity of microglia (MG) in the treatment of radiation brain injury (RBI).

The brain injury models of BV2 cells and Balb/C mice were established and randomly divided into three groups the normal control group (CON), the single radiation group (RAD), and the radiation plus CORM-3 intervention group (RAD+CORM). Immunofluorescence was used to observe the effects on activation of the MG. The expressions of inflammatory factors, such as intercellular adhesion molecule-1 (ICAM-1) and inducible nitric oxide synthase (iNOS), were detected by Western blot. Neuron apoptosis and regeneration in the radiation brain injury (RBI) model were detected by neuronal nuclear antigen (NeuN)+TUNEL and NeuN+BrdU double staining. A Morris water maze was used to assess the spatial learning and memory of the mice.

Within 48 h after radiation, CORM-3 inhibited activation of the MG, blocked the phosphorylation of P38, and increased the expression of ICAM-1 and iNOS. Therefore, CORM-3 might alleviate MG-mediated neuronal apoptosis and promote neural regeneration in the subgranular zone (SGZ) of the dentate gyrus of the hippocampus. BODIPY 493/503 research buy CORM-3 could increase the swimming distance and platform-stay time of the mice in the target platform quadrant after radiation.

CORM-3 could effectively improve the inflammatory response induced by activation of the MG, reduce neuronal apoptosis, promote neural regeneration, and improve the learning and memory performance of mice after radiation.

Considering the high mor-tality rate of lung cancer indicating the inadequacy of conventional treatment methods such as surgical resection, chemo-therapy and radiotherapy; new treatment strategies is an emerging area of interest. Nanoparticle-based drug and siRNA de-livery systems such as lipid, polymeric and inorganic nanoparticles, micelles and dendrimers are designed to enhance the bioavailability, stability and retention of the anti-cancer drug in the targeted regions of lung. These nanoparticle-based de-livery systems provide increased active ingredient half-life, targeting efficiency and reduced the required dose of the drug. Hence, they havemany advantages such as higher therapeutic efficacy, lower side effects, reducing adverse events. Combi-nations of active ingredients, anti-cancer agents and siRNA, can be formulated in nanoparticle-based delivery system that can be administered by variousroutes including inhalation and intravenous. In this review, development of lipidic and pol-ymeric nanoparticle-based drug and siRNA delivery systems used in the treatment of lung cancer are discussed.Adeno-associated virus (AAV) is one of the most promising viral gene delivery vectors with long-term gene expression and disease correction, featuring high efficiency and excellent safety in human clinical trials. During the production of AAV vectors, there are several quality control (QC) parameters that should be rigorously monitored to comply with clinical safety and efficacy. This review gives a short summary of the most frequently used AVV production and purification methods, focusing on the analytical techniques applied to determine the full/empty capsid ratio and the integrity of the encapsidated therapeutic DNA of the products.
