Rubin and Damjanov's latest volume of Pathology Reviews highlights the latest progress in the interface of biology and disease. Forefront techniques and experimental models that were once considered exotic or esoteric, are explored here in the context of understanding more fully the processes involved in human disease. Topics include: regulation of liver growth * contractile cells in lungs * mineral formation in bone * folate metabolism * the "riddle of the mast cell" * HLA antigens * interleukin 6 * IgA nephropathy * Goodpasture syndrome * anti-basement membrane glomerulonephropathy * molecular mechanisms of oncogenesis * molecular diagnosis of cancer * inhibition of intercellular communication in carcinogenesis * DNA repair and its pathogenetic implications * human and rat mammary tumorigenesis. Pathology Reviews * 1990 is essential reading for everyone concerned with the mechanisms of disease.
