Sleep in adolescents and young adults with type 1 diabetes: associations with diabetes management and glycemic control

Abstract

Multicolored proteins have allowed the color coding of cancer cells growing in vivo and enabled the distinction of host from tumor with single-cell resolution. Non-invasive imaging with fluorescent proteins enabled follow the dynamics of metastatic cancer to be followed in real time in individual animals. Non-invasive imaging of cancer cells expressing fluorescent proteins has enabled the real-time determination of efficacy of candidate antitumor and antimetastatic agents in mouse models. The use of fluorescent proteins to differentially label cancer cells in the nucleus and cytoplasm allow visualization of the nuclear–cytoplasmic dynamics of cancer cells in vivo, mitosis, apoptosis, cell-cycle position and differential behavior of nucleus and cytoplasm such as occurs during cancer-cell deformation and extravasation. Recent applications of the technology described here include linking fluorescent proteins with cell-cycle-specific proteins (FUCCI) such that the cells change color from red to green as they transit from G1 to S phases. With the macro and micro imaging technologies described here, essentially any in vivo process can be imaged, enabling the new field of in vivo cell biology using fluorescent proteins.
