Tattletales and T-Bow Update 20141018

http://works.bepress.com/gmcnamara/63

Tattletales is my concept to multiplex fluorescent protein biosensors ("Tattletales", which is also the overall concept name) and multicolor FP reporters ("T-Bow" for Rainbow T-cells and tumor cells) to study the physiology of live cells.

These are based on:

1. LacI-GFP :: LacO operator synthetic tandem repeat array (Robinett et al 1996 JCB, Fig 4A, http://jcb.rupress.org/content/135/6/1685.full.pdf )

2. the plethora of fluorescent protein biosensors - see page 1 of this "63" download site.

3. the many colors, and combinations of colors (CY11.5, CyPet-YPet 90% FRET, simple color combination fusions, Steven Vogel's "V6" and "V8" …

Enhancement Of Chronically Induced Breast Carcinogenesis By Combined Environmental And Dietary Carcinogens And Suppression By Dietary Agents, Lenora A. Pluchino Ph.D.

Lenora A. Pluchino, Ph.D.

Most breast cancers occur sporadically due to long-term exposure to low-dose carcinogens present in our environment and diet. American lifestyles involve frequent exposures to smoke, polluted air, and high temperature-cooked meats comprising multiple carcinogens, such as 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), benzo[α[alpha]]pyrene (B[α[alpha]]P), and 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). To investigate whether these carcinogens may act together to enhance breast cell carcinogenesis, we used our chronically-induced breast cell carcinogenesis model wherein we repeatedly expose non-cancerous human breast epithelial MCF10A cells to physiologically-achievable doses of carcinogens to progressively induce cellular acquisition of cancer-associated properties including reduced dependence on growth factors, anchorage-independent growth, increased cell proliferation, migration and …

Experimental Demonstration Of Bindingless Signal Delivery In Human Cells Via Microfluidics, Fang-Tzu Chuang

Fang-Tzu Chuang

The cellular signal transduction is commonly believed to rely on the direct “contact” or “binding” of the participating molecule reaction that depends positively on the corresponding molecule concentrations. In living systems, however, it is somewhat difficult to precisely match the corresponding rapid “binding,” depending on the probability of molecular collision, existing in the cellular receptor-ligand interactions. Thus, a question arises that if there is another mechanism (i.e., bindingless) that could promote this signal communication. According to this hypothesis, we report a cellular model based on the examination of intracellular calcium concentration to explore whether the unidentified signal delivery in cells …
