Summary
MicroRNAs (miRNAs) are small molecules crucial in disease development. This review explores how miR-17-92 and its paralogs contribute to cancer through altered expression and molecular pathways.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are short, non-coding RNA molecules regulating gene expression.
- Aberrant miRNA expression is implicated in various human diseases, including cancer.
- The miR-17-92 cluster and its paralogs are known oncogenic miRNA groups.
Purpose of the Study:
- To review the differential expression patterns of miR-17-92 and its paralogs in cancer.
- To elucidate the molecular mechanisms underlying their role in carcinogenesis.
- To consolidate current understanding of these miRNAs in cancer development.
Main Methods:
- Literature review of studies on miRNA expression and function in cancer.
- Analysis of reported molecular pathways involving miR-17-92 and paralogs.
- Synthesis of data on differential expression in various cancer types.
Main Results:
- miR-17-92 cluster and paralogs exhibit altered expression in multiple cancers.
- These miRNAs regulate key oncogenic pathways, including cell cycle, apoptosis, and angiogenesis.
- Specific expression patterns correlate with different cancer types and progression.
Conclusions:
- miR-17-92 and its paralogs are significant contributors to cancer development.
- Understanding their expression and mechanisms offers potential therapeutic targets.
- Further research is needed to fully unravel their complex roles in oncology.

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:56Treatment Resistent Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
