Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

Advanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Acidic microenvironment plays a key role in human melanoma progression through a sustained exosome mediated transfer of clinically relevant metastatic molecules [PDF]

, 2018
Background: Microenvironment cues involved in melanoma progression are largely unknown. Melanoma is highly influenced in its aggressive phenotype by the changes it determinates in its microenvironment, such as pH decrease, in turn influencing cancer cell

The Effect of Galactose on the Expression of Genes Regulated by Rrp6p [PDF]

, 2017
Gene expression is a multi-faceted phenomenon, governed not only by the sequence of nucleotides, but also by the extent to which a particular gene gets transcribed, how the transcript is processed, and whether or not the transcript ever makes it out of ...
