Correlation (R2) between resistance to 10 μM DA and levels of protection proteins
| Protein | R2 | P value |
|---|---|---|
| Trx | 0.0771 | n.s. |
| Bcl-2 | 0.0797 | n.s. |
| 1/Bax | 0.0015 | n.s. |
| Bcl-2/Bax | 0.0662 | n.s. |
| Trx/Bax | 0.0264 | n.s. |
| Trx × Bcl-2 | 0.0922 | n.s. |
| (Trx × Bcl-2)/Bax | 0.2729 | 0.03 |
R2 and P values were generated by using the Excel (Microsoft) software toolbox for regression analysis of data on expression levels of Trx, Bcl-2, and Bax (Table 2) vs. the percentage of inhibition of DNA synthesis with 10 μM dopamine (Fig. 1). n.s., not significant.
