Insights

Leukemia-inhibitory factor mRNA expression varies by tissue during prenatal development. Postnatal transition shows decreased leukemia-inhibitory factor mRNA in mononuclear cells.

Area of Science:

  • Developmental Biology
  • Immunology
  • Molecular Biology

Background:

  • Leukemia-inhibitory factor (LIF) is a cytokine with diverse biological roles.
  • Understanding LIF expression during human development is crucial for developmental and immunological insights.

Purpose of the Study:

  • To investigate the ontogeny of leukemia-inhibitory factor (LIF) mRNA expression in human fetal tissues and mononuclear cells.
  • To determine the tissue-specificity and developmental regulation of LIF mRNA isoforms.

Main Methods:

  • Analysis of leukemia-inhibitory factor (LIF) mRNA expression using molecular techniques.
  • Study of LIF mRNA isoforms across different stages of human development, from prenatal to postnatal periods.

Main Results:

  • Leukemia-inhibitory factor (LIF) mRNA expression demonstrated significant tissue-specificity during prenatal development.
  • A notable decrease in LIF mRNA isoforms was observed in mononuclear cells during the transition from neonatal to postnatal stages.

Conclusions:

  • Leukemia-inhibitory factor (LIF) expression is tightly regulated during human ontogeny.
  • Developmental stage significantly influences LIF mRNA expression patterns, particularly in immune cells.

General Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
RNA Splicing01:32

RNA Splicing

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...
Cell Specific Gene Expression01:58

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
Leaky Scanning02:28

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...
