Developmental progression is driven by specific spatiotemporal gene expression, which give rise to consistently patterned organisms despite environmental and genetic variation. The specific activation of robust gene regulatory networks that define tissue structure and individual cellular identity are necessary for tissue and cell specific programs to be activated. Cellular specification is guided by the interplay of intrinsic and extrinsic signals at specific developmental timepoints. The molecular mechanisms underlying the acquisition and maintenance of individual cellular identity remains a fundamental question across biological systems. Understanding the regulatory networks controlling the acquisition of neuronal identity, diversity, and connectivity in the formation of …

Germ cells give rise to gametes and link generations by passing genetic information from parent to offspring. Gametes arise from, in many sexually reproducing organisms, germline stem cells (GSCs) which are set aside early during development. GSCs have an amazing capacity to undergo self-renewal to give rise to a pool of undifferentiated cells, while also differentiating to generate specialized germ cells such as haploid gametes. Upon female GSC differentiation, mitotically dividing germ cells can initiate meiosis, and mature within a follicle. During maturation, the specified oocyte is provided with a trust fund of RNAs and proteins for the next generation …

Bacterial infections and the rise of antibiotic resistance, especially multidrug resistant strains, have generated a clear need for discovery of novel therapeutics. Most antibiotics in use today are derivatives of previous antibiotics to which resistance mechanisms already exist, and traditionally they have a single target: either a protein or rRNA. Gram-positive bacteria regulate the expression of several essential genes or operons using a mechanism called the T-box. The T-box is a structurally conserved riboswitch-like gene regulator in the 5’-untranslated region (UTR) of numerous essential genes of Gram-positive bacteria. T-boxes are stabilized by cognate, unacylated tRNA ligands, allowing the formation of …
