Hence, these results supported the fact that green tea contained potential compounds with an ability to inhibit the cancer by disrupting the co-chaperon p23 activity.
The Rho GTPases Rac (Ras-related C3 botulinum toxin substrate) and Cdc42 (cell division control protein 42 homolog) regulate cell functions governing cancermalignancy, including cell polarity, migration, and cell-cycle progression.
The results showed that although there was slight difference in the protein expression of R-Ras between the breast cancer tissues and normal tissues, the activation of R-Ras was reduced in 63.8% of the cancer tissues when compared to the normal tissue samples.
Cell treatment with gedunin leads to cancer cell death by apoptosis through inactivation of p23 and activation of caspase 7, which cleaves p23 at the C terminus.
Whereas HRAS, NRAS, and KRAS frequently acquire transforming missense mutations in human cancer, little is known of the oncogenic roles of other small GTPases, including Ras-related C3 botulinum toxin substrate (RAC) proteins.
