The Central Dogma01:20

The Central Dogma

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Upstream Processing01:27

Upstream Processing

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...
Reporter Genes02:11

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
Commonly used reporter...
Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Area of Science:

  • Biotechnology
  • Molecular Biology
  • Protein Expression

Background:

  • Recombinant gene expression is vital in research and industry, with Escherichia coli and Pichia pastoris dominating literature.
  • Existing systems like E. coli and P. pastoris can lead to misfolding or inadequate post-translational modification of eukaryotic proteins.

Discussion:

  • The limitations of current systems necessitate exploring novel recombinant expression platforms.
  • Identifying alternative systems is essential for the successful expression of challenging eukaryotic genes.

Key Insights:

  • Drosophila melanogaster S2 insect cells and human embryonic kidney 293 (HEK293) cells offer significant promise for recombinant protein production.
  • These systems may overcome the limitations of traditional expression hosts, enabling better protein folding and modification.

Outlook:

  • Further experimental screening is required to identify optimal systems for diverse eukaryotic gene expression.
  • Developing a universal expression system remains a long-term goal, but advancements in systems like S2 and HEK293 cells are encouraging.
