Insights

Long non-coding RNAs (lncRNAs) play a crucial role in multiple myeloma (MM) pathogenesis. Further research into lncRNAs may reveal novel biomarkers for this hematooncological malignancy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Multiple myeloma (MM) is a significant hematooncological malignancy characterized by malignant plasma cells in the bone marrow.
  • Despite advancements in treatment, the precise pathogenesis of MM remains incompletely understood.
  • Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in the development and progression of various cancers, including MM.

Purpose of the Study:

  • To review the current understanding of non-coding RNAs (ncRNAs), with a specific focus on lncRNAs.
  • To elucidate the involvement and significance of lncRNAs in the pathogenesis of multiple myeloma.
  • To explore the potential of lncRNAs as diagnostic or prognostic biomarkers for MM.

Main Methods:

  • Literature review of existing research on ncRNAs and MM.
  • Analysis of studies investigating lncRNA expression and function in MM.
  • Synthesis of current knowledge regarding the biological roles of lncRNAs in MM development.

Main Results:

  • Over 15,000 human lncRNA molecules have been identified, exhibiting diverse functions and cell-specific distributions.
  • lncRNAs are implicated in fundamental biological processes such as proliferation, apoptosis, metabolism, and differentiation.
  • Evidence strongly suggests the involvement of lncRNAs in the tumorigenesis and progression of multiple myeloma.

Conclusions:

  • lncRNAs are integral to the biological processes underlying multiple myeloma.
  • The established role of lncRNAs in MM development highlights their potential utility as biomarkers.
  • Further investigation into lncRNAs could lead to novel diagnostic and therapeutic strategies for multiple myeloma.

lncRNA - 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...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

piRNA - Piwi-interacting RNAs

PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Nursing Code of Ethics

The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...
