Central dogma of molecular biology, a term coined by Francis Crick in 1958 was considered to be the cornerstone of molecular biology unless molecular biologists challenged the idea after ground-breaking discovery of non-coding RNAs. Discovery of microRNAs marked a new era and revolutionized our understanding related to puzzling mysteries about intermediate steps between transcription and translation. Technological advancements have spawned a multitude of platforms for profiling of long-noncoding RNAs and miRNAs in different cancers. Detailed investigation of mRNA targets of miRNAs has enabled high-order analyses of interconnected networks and revealed affected pathways in different cancers. miR-143 has emerged as a multi-talented tumor suppressor microRNA having considerable ability to inhibit and prevent cancer via regulation of myriad of oncogenes. In this review, we will summarize most recent evidence related to characteristically unique ability of miR-143 to target different oncogenic mRNAs in different cancers. We will also comprehensively discuss how scientists have identified multiple long non-coding RNAs reportedly involved in promoting the expression of oncogenes by interfering with miR-143 mediated targeting of these oncogenes. Because of excellent ability of miR-143 to effectively target oncogenic mRNAs, researchers have started to focus on use of miR-143 mimics to restore expression of miR-143 in various cancers.
