Sulfurtransferases: Essential Enzymes for Life stands as the first comprehensive resource on this increasingly important class of enzymes. Following an introduction to the field from the Editors, each chapter covers a specific sulfurtransferase, including its basic biology and roles in healthy functioning, disease, drug discovery, and other biotechnological applications. The physiological function for each enzyme is considered in depth, along with regulation mechanisms, pharmacological inhibitors, and pathology and conditions related to altered enzymatic activity. Sulfurtransferases discussed include rhodanese, MST, thiosulfate-thiol sulfurtransferase, tRNA uracil 4-sulfurtransferase, thiosulfate-dithiol sulfurtransferases, biotin synthase, cysteine desulfurase, lipoyl synthase, molybdenum cofactor sulfurtransferase, thiazole synthase, molybdopterin synthase sulfurtransferase, molybdopterin synthase, tRNA-uridine 2-sulfurtransferase, tRNA-5-taurinomethyluridine 2-sulfurtransferase, tRNA-5-methyluridine (54) 2-sulfurtransferase, and L-aspartate semialdehyde sulfurtransferase, among others. Here, researchers will discover key knowledge and recent advances to bring forward new studies on this increasingly relevant class of enzymes, while clinicians may apply new findings in medical practice.

Of the many markers for cancer stem cells (CSCs) in lung cancer reported to date, the cell surface antigen CD133, nuclear ss-catenin accumulation, the side population phenotype, and high aldehyde dehydrogenase (ALDH) activity seem to be most reliable. This book reviews the results of studies on lung CSCs and discusses the significance of these markers from a biological, pathological, and clinical viewpoint. Twenty-seven lung cancer cell lines (nine small cell lung carcinoma (SCLC) cell lines and eighteen non-small cell lung carcinoma (NSCLC) cell lines) were examined for mRNA and protein expression and fractions of cells with activity.
