To determine the growth kinetics of BEAS-2B cells and putative transformed variants, 103 cells from exponentially growing cultures were re-plated into 96-well plates in complete LHC-9 medium.
To determine the average doubling time of BEAS-2B cells and their transformed variants, 200 to 300 cells from exponentially growing cultures were plated into 60 mm diameter dishes in complete LHC-9 medium.
They require constant monitoring to ensure that transformed variants, readily detected morphologically by their more refractile appearance and lack of contact inhibition, do not overgrow.
Alterations of the P16 gene, like deletions, hypermethylation and mutations were reported in 30% of transformed variants of non-Hodgkin's lymphoma (NHL).
This work demonstrates the versatility of the CoGAPS matrix factorization algorithm to infer biological signaling nodes and intermediaries as they relate to specific gene expression in immortalized HaCaT and transformed variants thereof.
These stem cells may be transformed variants of normal neural progenitor cells, but the functional identity of these cells (i.e., stem cells or neural progenitor cells) remains controversial [ 4, 6, 7].
The onset of these processes allows the normal healthy cell and its transformed malignant variant to have an exaggerated apoptotic response to both intrinsic DNA damage and also to chemotherapy induced therapeutic DNA damage.
Receptor dimerization is not a factor in the signalling activity of a transforming variant epidermal growth factor receptor (EGFRvIII).
Another similar murine model of oligodendroglioma utilizes transgenic expression of a transforming variant of EGFR, v-erbB, under the S100ß promoter (85).
Left panels show the growth assay of the yeast Δ mep1,2,3 strain transformed with insertion variants on solid media containing 2 mM NH4Cl or 1 mM arginine (growth control) as the sole nitrogen source for 3 days.
For the calculation of the inverse Laplace transform, a variant of the Weeks algorithm with automatic parameter tuning is employed.
