On the origins and development of the (32)P-postlabelling assay for carcinogen-DNA adducts.

abstract：:Highly invasive and rapidly fatal, small-cell lung cancer (SCLC) has been an insurmountable gulf since discovery. Innate immunity plays a vital role in anti-tumor response, among which macrophages contribute to an indispensable character. Here, we found that macrophage infiltration in SCLC reduced significantly in a s...
