Spermatogenesis requires radical restructuring of germline chromatin at multiple stages, involving coordinated waves of DNA methylation/demethylation, histone modification, and the replacement and removal that occurs before, during, and after meiosis. This Special Issue will draw together papers that address all aspects of chromatin organization and dynamics in the male germ line, in humans, and in model organisms. In particular, we will invite authors to discuss novel methods for studying germline chromatin structure, the interplay between chromatin structure and susceptibility to DNA damage and mutation, chromatin modifications associated with epigenetic inheritance in the early embryo, and the impact this work has for understanding natural fertility and improving assisted reproduction techniques.

The Special Issue "Anticancer Drugs 2021" of Pharmaceuticals is focused on recent significant advances in the design, synthesis, molecular mechanism of action and therapeutic applications of anticancer drugs. This collection of preclinical research papers and reviews includes designed chemotherapeutic agents, targeted therapies and biological agents. The rationalization for the biological activity of these drugs is presented, which helps to guide the design of more effective agents. Structure–activity relationships, together with the biological context in which targets are selected for oncology drug development, are also considered.
