Hebp2-KO Mouse

Hebp2, also known as heme-binding protein 2, is involved in multiple biological processes. It has been associated with the regulation of microtubule dynamics and mitotic spindle behavior through its interaction with ALG-2, which is significant for genomic stability in cells. Abnormalities in the ALG-2/Hebp2 interaction can lead to improper mitosis [2].

In breast cancer, specifically triple-negative breast cancer (TNBC), overexpression of Hebp2 enhanced the viability of MDA-MB-231 cells in response to cisplatin and BCNU, while CRISPR/Cas9-mediated Hebp2-knockout reduced cell viability in response to these drugs. This indicates that Hebp2 may play a role in resistance to cisplatin and BCNU, which induce DNA cross-links [1]. In ovarian cancer, Hebp2 accelerates cancer progression, modifies the immune landscape, drives macrophage polarization from M0_TAM to M2_TAM, and contributes to carboplatin resistance both in vitro and in vivo [3].

In conclusion, Hebp2 is important in regulating microtubule-related processes during cell division. Its role in cancer, especially in conferring resistance to certain chemotherapeutic drugs in breast and ovarian cancers, makes it a potential biomarker and therapeutic target. The use of gene-editing techniques like CRISPR/Cas9 in cell models has been crucial in uncovering these functions, providing insights into the etiology and potential treatment of related diseases.
