A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
A correlation between the periplasmic embellishment of the flagellar motor and its stator system type is described, motors with dual H+-dependent stator systems have one periplasmic ring formed by MotY.
The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.
By inhibiting the activation of NF-κB, HIV-1 Vpu exerts much broader immunosuppressive effects than previously anticipated and may be an important determinant of chronic inflammation in HIV-1 infected individuals.
In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.
The requirements for preinitiation complex formation/stability and transcription by RNA polymerase II in yeast cells are different from those in vitro, thereby altering the current view of basal transcription.
