Background: Glutamate is an important excitatory neurotransmitter in the pedunculopontine tegmental (PPT) nucleus. The cardiovascular effect of glutamate and its non-N-methyl-D-aspartate (NMDA) receptor in the PPT is unknown; therefore, we evaluated ...

Microinjection of dsRNA in Tardigrades [PDF]
Classical genetic analysis in the tardigrade Hypsibius exemplaris is a challenge because these animals are parthenogens. The publication of the H. exemplaris genome has facilitated the study of targeted genes by RNA interference (RNAi), a robust mechanism to disrupt gene function. This protocol describes microinjection of double-stranded RNA (dsRNA) in

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Viroids are single-stranded noncoding RNA molecules of 250–400 nucleotides that cause plant diseases. One of the two families of viroids is Pospiviroidae, the members of which replicate in the nuclei of host cells.

Direct introduction of cloned DNA into the sea urchin zygote nucleus, and fate of injected DNA [PDF]
A method is described for microinjection of cloned DNA into the zygote nucleus of Lytechinus variegatus. Eggs of this species are unusually transparent, facilitating visual monitoring of the injection process.

Transcriptionally inactive oocyte-type 5S RNA genes of Xenopus laevis are complexed with TFIIIA in vitro [PDF]
An extract from whole oocytes of Xenopus laevis was shown to transcribe somatic-type 5S RNA genes approximately 100-fold more efficiently than oocyte-type 5S RNA genes.

Trade-off between somatic and germline repair in a vertebrate supports the "expensive germ line" hypothesis [PDF]
The disposable soma theory is a central tenet of the biology of aging where germline immortality comes at the cost of an aging soma [T. B. L. Kirkwood, Nature 270, 301–304 (1977); T. B. L. Kirkwood, Proc. R. Soc. Lond. B Biol. Sci. 205, 531–546 (1979); T.

Reconfigurable Microenvironments Uncover Mechano‐Sensing Timescales and Direct Cell Polarity
A synthetic DNA‐crosslinked cell culture matrix enables control over the mechanical microenvironment surrounding cells. Independent tuning of stiffness and stress relaxation uncovers distinct timescales of mechano‐sensing that regulate cell behavior.
