Interaction Between Host MicroRNAs and the Gut Microbiota in Colorectal Cancer

 Nanopore Sequencing – Bio Basic Asia Pacific Pte Ltd 

    It is always vital to know what is fairly recent in the world of a geneticist. Learning which method of sequencing will help the process of depicting snips.  The research article, Interaction between host microRNAs and the gut microbiota in colorectal cancer. ASM, 3(3): 1-13, has found microRNA plays apart as a "host-microbiome" in colorectal cancer.

    It is important to note that our study uses 16S rRNA gene sequencing to characterize microbiome taxonomic composition and computationally predicted pathway composition using PICRUSt v1.0.0 (71). Although this method is widely used, metagenomic shotgun sequencing can be more accurate and informative in understanding the functional makeup of a microbial community. Similarly, to impute miRNA functional profiles, we used an in silico prediction method, miRPath (71, 72). While both of these methods have been rigorously tested and validated with experimental data, the results remain predictions and may not represent the real biological system (71, 72). Another limitation of our approach is that it identifies correlations and not causal relationships. Nevertheless, this approach allows us to generate a microbiome- and miRNA transcriptome-wide characterization of potential interactions, which shed light on potential new mechanisms of host-microbiome interactions.” (Yuan et al 2018). This study is using specific techniques to receive their answers. It then shows these techniques do have their benefits with certain aspects but has its drawbacks

IgA Defense Starts in the Gut

 Subject: Immune Defense and Immunoglobulin cell defense 

Article:: ¨Protecting the brain from infection may start with a gut reaction¨ 



In the article, ¨Protecting the brain from infection may start with a gut reaction¨ a study had indicated that immune cells had initially learned to detect pathogens in the gut. The study even further discovered that these immune defense cells are even found in the brain. The brain and spinal cord is encased in three protective layers called meninges that have their own immune cells known as immunoglobulin A. Also known as IgA, it is a kind of antibody in the blood that helps combat pathogens and are found primarily in the respiratory tract, gastrointestinal tract etc. When it comes to the brain IgA is an antibody-producing plasma cell in the leathery meningeal work to protect itself from foreign invaders that want to break through the meningeal layers. Knowing that the gut plays a role in defending the brain of diseases, it is possible that boosting gut bacteria could potentially aid in autoimmune diseases, infections and viruses. Which as shown in mice, gut microbial cells were found in those that had multiple sclerosis. This could be a turning point for many diseases, not just brain ones. If the human body is capable of healing itself from serious illness it is possible that illness like ASL, autoimmune diseases,multiple sclerosis and even alzheimers or dementia could be combated much earlier in a person's life.
