Summary
The MYCN gene influences neuroblastoma development by regulating noncoding RNAs, including microRNAs and long noncoding RNAs. Understanding this interplay is crucial for targeting pediatric neuroblastoma.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Neuroblastoma is a pediatric cancer originating from the sympathetic nervous system.
- MYCN proto-oncogene amplification is a key driver in ~20% of neuroblastomas, correlating with aggressive disease and poor prognosis.
- N-myc protein, encoded by MYCN, regulates numerous genes involved in critical cellular processes.
Purpose of the Study:
- To review the current understanding of the relationship between N-myc and noncoding RNAs in neuroblastoma.
- To elucidate how this interaction contributes to the development and progression of neuroblastoma.
- To highlight the role of microRNAs and long noncoding RNAs in N-myc-mediated tumorigenesis.
Main Methods:
- Literature review of studies investigating N-myc and noncoding RNA expression in neuroblastoma.
- Analysis of research on the regulatory functions of N-myc on microRNAs (miRNAs) and long noncoding RNAs (lncRNAs).
- Synthesis of findings on the reciprocal regulation between N-myc and noncoding RNAs.
Main Results:
- N-myc modulates the expression of various microRNAs and long noncoding RNAs (e.g., T-UCRs, ncRAN) in neuroblastoma.
- MicroRNAs play critical roles in gene regulation and are aberrantly expressed in neuroblastoma pathogenesis.
- Both N-myc-regulated tumor suppressor miRNAs and miRNAs that repress MYCN expression are significant.
Conclusions:
- The interplay between N-myc and noncoding RNAs is a critical factor in neuroblastoma tumorigenesis.
- Noncoding RNAs, particularly miRNAs, are key targets for understanding and potentially treating MYCN-driven neuroblastoma.
- Further research into N-myc's regulation of lncRNAs and their collective role is warranted.

01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
01:13Formation of Muscle Fibers from Myoblasts
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription factors...

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
