GalphaI2 Inhibitors Block Chemotherapy-Induced Prostate Cancer Cell Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for prostate cancer, such as androgen deprivation therapy and chemotherapy, can lead to the development of castration-resistant prostate cancer and increase the risk of metastasis by inducing cancer cell invasion and migration.
Innovation Solution
Administering a G(alpha)i2 inhibitor in combination with chemotherapeutic drugs to reduce cell migration and inhibit cancer cell metastasis in prostate cancer patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemotherapeutic drugs are administered to treat cancer, then cancer cell death is induced, but cancer cell migration and metastasis are increased
Solution Approach 1:
The patent introduces Gαi2 as a molecular intermediary target that mediates the harmful migratory effects of chemotherapy. By administering Gαi2 inhibitors, the harmful migratory signal transduced by Gαi2 protein is blocked, preventing chemotherapy-induced metastasis while preserving the therapeutic anti-cancer effects of the chemotherapeutic agents
Solution Approach 2:
The patent extracts and isolates the specific harmful migratory pathway mediated by Gαi2 from the overall chemotherapy response. By selectively inhibiting Gαi2 with specific inhibitors, only the harmful migratory component is removed while the beneficial cytotoxic effects of chemotherapy are maintained
2Reliability
If androgen deprivation therapy is used to treat prostate cancer, then androgen-dependent cancer growth is inhibited, but castration-resistant prostate cancer develops
Solution Approach 1:
The patent applies preliminary anti-action by administering Gαi2 inhibitors alongside or sequentially with androgen deprivation therapy to preemptively block the migratory and adaptive responses that lead to castration resistance. This prevents cancer cells from developing resistance mechanisms before they can emerge
