The core components of the intrinsic mitochondrial apoptotic pathway are proteins of the Bcl-2 family. Members of this family can be subdivided into pro- and anti-apoptotic proteins. Although the precise mechanisms of how they regulate apoptosis are still unclear, the stoichiometric balance of pro and antiapoptotic proteins of this family seems crucial. High concentrations of the antiapoptotic proteins Bcl-2, Bcl-xL, A1 or Mcl-1 can inhibit the mitochondrial apoptotic pathway.

Diverse strategies have been employed to target Bcl-2 and the related proteins Bcl-xL and Mcl-1:

(1) Antisense techniques to downregulate protein levels

(2) Application of BH3 domain peptides

(3) Synthetic small molecule drugs, which interfere with the complex formation of anti- and proapoptotic Bcl-2 family members, thereby setting previously quenched proapoptotic proteins on the loose.


Solutions For you

Creative Bioarray can assist with studying BCL2 related targets, discovering drugs, and studying disease mechanisms. Our services include but are not limited to:

Construction of Antisense Expression Vector

Taking mRNA as the target molecule, antisense drugs bind to a specific part of the mRNA molecule to regulate gene expression at the splicing or translation level, which is called antisense technology.

Antisense oligonucleotide technology has obvious advantages:

  • Antisense nucleic acid is a sequence for a specific target mRNA (DNA), and the gene sequence is known.
  • Antisense nucleic acid has only 15-30 bases, simple structure, easy to design and large-scale synthesis in vitro.
  • The entry of antisense nucleic acid into the cell has nothing to do with the cell cycle, and it can enter both proliferative and non-proliferative cells.

Relying on a professional cell death research platform and an experienced team, Creative Bioarray can design and synthesize antisense oligonucleotide sequences according to your research goals and requirements to help your gene function and clinical treatment research.

Screening of Small Molecule Bcl-2/Bcl-x L Modulators

The BH3 domain comprises a 9-amino-acid amphipathic a-helix that binds to a hydrophobic pocket of Bcl-2-like antiapoptotic proteins. Therefore, peptides and small molecules mimicking BH3 domain proteins aim at disrupting this complex, thereby sensitizing cells to apoptosis.

To enhance cell entry of BH3 domain peptides, Creative Bioarray can provide several strategies like the coupling of BH3 peptides to protein transduction domains from HIV Tat protein, HSV VP22 or Drosophila Antennapedia protein (ANT), conjugation to fatty acids or delivery by cationic lipids.

In addition to BH3 peptides, Creative Bioarray can help you discover and identify small molecules that interfere with the function of Bcl-2/Bcl-xL by screening chemical libraries.
