Cell Organelles:Cell organelles represent the many smaller membrane-bound objects located within cells. Examples of cell organelles include ribosomes, mitochondria, endoplasmic reticulum, lysosomes, cytoskeleton, and Golgi complex. Each organelle serves a specific function and purpose for the cell....
Inactivation of miR-133a causes developmental abnormalities due to aberrant cell proliferation and increased smooth muscle gene expression16. In adult skeletal muscles, miR-1/133a is required for metabolic maturation by suppressing the Dlk1-Dio3 miRNA/lncRNA mega-cluster via MEF2A14. Surprisingly, ...
cell, is controlled by the activity of cyclin-dependent kinases (CDKs) (Morgan1997) (Figs.1,2). Although the control machinery displays many species-specific variations and is subject to adaptation, the general principle of CDK-driven progression through mitosis appears to be conserved from ...
Precision control of molecular activities and chemical reactions in live cells is a long-sought capability by life scientists. No existing technology can probe molecular targets in cells and simultaneously control the activities of only these targets at
(Supplementary Fig.3C). Next, ultrasound stimulation was utilized to activate Ca2+-dependent signaling pathway resulting in NFAT activation. To maintain the sterility, transfected HEK293 cells were insonated using a transducer placed at the bottom of the cell culture plate (Fig.2B). The parameters...
The center of the transducer was left uncoated with gold in order to permit bright-field light to reach the sample, allowing us to align optics and obtain even illumination for DIC imaging. Recordings were carried out in response to peak negative pressures ranging from 0.2–0.25 MPa, as...
Intestinal stem cell (ISC) divisions in Drosophila represent an ideal model system to study the regulation of SC division modes during regeneration, growth, damage, and aging. The Drosophila intestine is lined with a pseudo-stratified epithelium that is regenerated by ISCs after damage to ensure ti...
