lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.0K
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...

Embryonic Stem Cells

32.5K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

5.1K
Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

14.9K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

RNA Splicing01:32

RNA Splicing

60.7K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Area of Science:

  • Molecular Biology
  • Developmental Biology
  • Genomics

Background:

  • Non-coding RNAs (ncRNAs) regulate gene expression post-transcriptionally without protein-coding.
  • ncRNAs, including lncRNAs, miRNAs, circRNAs, snoRNAs, and piRNAs, are key regulators in embryonic development.
  • Single-cell RNA sequencing (scRNA-seq) enables high-resolution analysis of cell-to-cell variability.

Purpose of the Study:

  • To investigate the expression patterns of various ncRNAs during embryonic development.
  • To elucidate the specific roles of single-cell ncRNA expression in developmental processes.
  • To highlight the application of scRNA-seq in ncRNA research.

Main Methods:

  • Utilizing single-cell RNA sequencing (scRNA-seq) to profile ncRNA expression at the individual cell level.
  • Analyzing the heterogeneity of ncRNA expression across different cell types and developmental stages.
  • Integrating scRNA-seq data to understand ncRNA regulatory networks.

Main Results:

  • Demonstrated diverse expression profiles of ncRNAs (lncRNAs, miRNAs, circRNAs, snoRNAs, piRNAs) across embryonic cells.
  • Identified specific ncRNAs associated with key developmental events and cell fate decisions.
  • Showcased the power of scRNA-seq in capturing cell-specific ncRNA functions.

Conclusions:

  • Single-cell ncRNA expression is critical for orchestrating complex embryonic development.
  • scRNA-seq provides unprecedented resolution for studying ncRNA roles in development.
  • Further research into single-cell ncRNA dynamics will advance our understanding of developmental biology.
