Pb chromate Anchorage Independence<br />

(0.1–1 µM <strong>for</strong> 48 h)<br />

Pb chromate Anchorage Independence<br />

(0.1–1 µM <strong>for</strong> 48 h)<br />

Pb chromate Morphological Trans<strong>for</strong>mation<br />

(2 µg/mL <strong>for</strong> 24 h, per<strong>for</strong>med<br />

3 times immediately after<br />

passage)<br />

Anchorage Independence (0.2–<br />

2 µg/mL or cells isolated during<br />

morphological trans<strong>for</strong>mation)<br />

Neoplastic Trans<strong>for</strong>mation (cells<br />

isolated during morphological<br />

trans<strong>for</strong>mation)<br />

None Pb chromate-induced concentration-dependent increase in<br />

anchorage independence.<br />

None Pb chromate-induced concentration-dependent increase in<br />

anchorage independence.<br />

None Pb chromate induced foci <strong>of</strong> morphological trans<strong>for</strong>mation<br />

after repeated exposure and passaging.<br />

Pb chromate did not induce anchorage independence, but<br />

cells from the foci obtained during morphological<br />

trans<strong>for</strong>mation.<br />

Pb chromate did not induce neoplastic trans<strong>for</strong>mation in the<br />

cells from the foci obtained during morphological<br />

trans<strong>for</strong>mation.<br />

Studied as a chromate compound. Role <strong>of</strong> Pb not mentioned<br />

or considered.<br />

3-aminotriazole (3-AT)<br />

(80 mM to inhibit<br />

catalase)<br />

Pb acetate-induced concentration-dependent increase in<br />

anchorage independence. Anchorage independence not<br />

affected by 3-AT.<br />
