The RNA interference (RNAi) era, started by Fire and Mello in 1998 completely changed the vision of research involving cell control and therapeutic intervention. RNAi machinery starts from a long dsRNA and pre-microRNA (pre-miRNA) that is cleaved by the ‘Dicer’ enzyme in a short dsRNA fragments called small interfering RNA (siRNA) and miRNA, respectively. This, […]
Immunohistochemistry has helped to make surgical pathology the ‘gold standard’ for tumour diagnosis. Antibodies have been used extensively as the molecular probes; however, there have been issues with their specificity, which is the most critical determining factor in IHC.
Previous reports have suggested that 40-50 % of diagnostic inconsistencies are related to poor antibody selection, cross […]
The blood brain barrier (BBB) is a highly specialized network of blood vessels that effectively separates the brain environment from the circulatory system. Delivering drugs into the brain environment has historically been a challenge. This is due to the nature of the BBB anatomy, as it is composed of polarized endothelial cells that are connected […]
Cancer histopathology is currently the preferred method for detecting microscopic anatomical changes in tissue sections, making the discovery of cancer biomarkers critical for early diagnosis and treatment. Antibodies have been used extensively as the molecular probes; however, the production of antibodies requires a series of complicated and time-consuming processes.
There is no question that aptamers can […]
