Summary: Deconvolution microscopy has historically been painfully slow. The early vendors were:

- Scanalytics (Carrington and Fay), commercialized to try to sell expensive, specialized array processors made by CSPI (the CSPI box likely had less computing power than a first gen smartphone).

- Applied Precision (Sedat …

Light Microscopy Reflection Focusing Cells And Coverglass, George Mcnamara May 2015

Light Microscopy Reflection Focusing Cells And Coverglass, George Mcnamara

George McNamara

Light Microscopy Reflection Focusing Cells and Coverglass 20150520Wed

Many light microscopes have the capability of using camera based brightfield, phase contrast, or fluorescence to find the most contrasty specimen focus. When I worked for UIC (1992-1997) we offered this with a combination of Ludl MAC2000 controller, Z-drive, video card thingy, and video camera (most customers at the time used analog video cameras).

Many automated light microscopes now have clever -- and pricey -- autofocus systems based on an NIR LED structured illumination reflecting light off the bottom of the coverglass.

I encourage a simpler approach - my hardware details are …


Iron Alters Cell Survival In A Mitochondria-Dependent Pathway In Ovarian Cancer Cells., Edward Haller Feb 2015

Iron Alters Cell Survival In A Mitochondria-Dependent Pathway In Ovarian Cancer Cells., Edward Haller

Edward Haller

ABSTRACT The role of iron in the development of cancer remains unclear. We previously reported that iron reduces cell survival in a Ras/mitogen-activated protein kinase (MAPK)-dependent manner in ovarian cells; however, the underlying downstream pathway leading to reduced survival was unclear. Although levels of intracellular iron, ferritin/CD71 protein and reactive oxygen species did not correlate with iron-induced cell survival changes, we identified mitochondrial damage (via TEM) and reduced expression of outer mitochondrial membrane proteins (translocase of outer membrane: TOM20 and TOM70) in cell lines sensitive to iron. Interestingly, Ru360 (an inhibitor of the mitochondrial calcium uniporter) reversed mitochondrial changes and …

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.

Enhancement Of Chronically Induced Breast Carcinogenesis By Combined Environmental And Dietary Carcinogens And Suppression By Dietary Agents, Lenora A. Pluchino Ph.D. Aug 2014

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 Jul 2014

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 …

Tattletales: multiplex fluorescent protein biosensors by spatial localization with TALE-FPs, Cas9-FPs, ZF-FPs, LacI-FPs, TetR-FPs, etc.

T-Bow: Rainbow T-cells and Tumor cells (and ES cells, iPS cells, other cells and organisms). You can think of this as "Brainbow meets TALENs/Cas9/ZFNs/other DNA sequence specific binding proteins".

Robert Murphy's TypIC (typical cell Chooser,

http://murphylab.web.cmu.edu/services/TypIC/

now superseded by PSLID and SLIF

http://murphylab.web.cmu.edu/services/ ), was a "game changer" for me with respect to cell shape analysis. Rather than trying to compute the average of (say) a triangle and a pentagon ... which might result in a square, or a rectange, or some bizarre quadrilateral ... R.M. advocated using the median. OK, in a 2 member dataset this would result in averaging the two shapes (if use the standard way to calculate median of even number datasets), but this could be avoided …
