Abstract:
Long noncoding RNAs (LncRNA), a class of transcripts with lengths >200 nt, play a master role in the regulation of cancer pathogenesis. Recently, the CRISPR-Cas9 system has been explored as a revolutionary genome editing tool for molecular biology. Growing evidence shows that LncRNAs can be targeted by the CRISPR-Cas9 system used for evaluating its function. Thus, the CRISPR-Cas9 systems provide a novel gene-editing strategy for the modification of LncRNA expression. This review summarizes current knowledge of the functions and underlying mechanisms of LncRNA by CRISPR-Cas9. Emerging strategies for non-viral/viral delivery of CRISPR-Cas9 in a clinical context are also discussed.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
