| | GO:0010524 | | positive regulation of calcium ion transport into cytosol | | Any process that increases the rate of the directed movement of calcium ions into the cytosol of a cell. The cytosol is that part of the cytoplasm that does not contain membranous or particulate subcellular components. |
| | GO:0050850 | | positive regulation of calcium-mediated signaling | | Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling. |

| | GO:0032355 | | response to estradiol | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of stimulus by estradiol, a C18 steroid hormone hydroxylated at C3 and C17 that acts as a potent estrogen. |
