[Construction and identification of cbfa1 and satb2 co-expression vector]

Area of Science:

• Molecular Biology
• Gene Expression Systems
• Lentiviral Vectors

Background:

• The transcription factors core-binding factor alpha 1 (cbfa1) and SATB homeobox 2 (satb2) play critical roles in cellular differentiation and development.
• Understanding their coordinated function requires robust expression systems.

Purpose of the Study:

• To construct a single lentiviral eukaryotic expression vector enabling co-expression of cbfa1 and satb2.
• To facilitate downstream functional studies of cbfa1 and satb2 in relevant biological systems.

Main Methods:

• Genes cbfa1 and satb2 were amplified via PCR and cloned into the pIRES vector.
• The cbfa1-IRES-satb2 fragment was ligated into the pLentinTrident1-CMV lentiviral vector.
• Vector construction was confirmed by PCR, restriction enzyme digestion, and DNA sequencing.

Main Results:

• A recombinant lentiviral eukaryotic expression vector, pLentinTrident1-CMV-cbfa1-Ires-satb2, was successfully generated.
• Co-expression of cbfa1 and satb2 is enabled by the internal ribosomal entry site (IRES) element.
• Verification of the construct's integrity was confirmed through molecular analyses.

Conclusions:

• The successful construction of the lentiviral vector provides a valuable tool for studying cbfa1 and satb2.
• This vector lays the groundwork for investigating the synergistic or individual roles of cbfa1 and satb2 in biological processes.
