Nucl. Acids Res. 33, 4762-4774. Characterization of SpPol4, a unique X-family DNA polymerase in Schizosaccharomyces pombe. 2005

Gonzalez-Barrera, S., Sanchez, A., Ruiz, J.F., Juarez, R., Picher, A.J., Terrados, G., Andrade, P. and Blanco, L.

Notes: An open reading frame encoding a putative DNA polymerase, SpPol4, was amplified from S. pombe genomic DNA by PCR. The resulting PCR product was cloned into the pGEM®-T Easy Vector, and the sequence was verified. Based on sequence analysis, the authors hypothesize that SpPol4 has deoxyribose phosphate (dRP) lyase activity, suggesting that the enzyme plays a role in base excision repair. The authors perform a dRP lyase activity assay with an oligonucleotide substrate labeled using [32P]ddATP and terminal deoxynucleotidyl transferase. (3465)

Biochem. Biophys. Res. Commun. 309, 222–231. Hypoxia induces apoptosis in SV40-immortalized rat proximal tubular cells through the mitochondrial pathways, devoid of HIF1-mediated upregulation of Bax. 2003

Tanaka, T., Hanafusa, N., Ingelfinger, J.R., Ohse, T., Fujita, T., and Nangaku, M.

Notes: ImProm-II™ Reverse Transcriptase was used in real time RT-PCR to measure the ratio of Bax to Bcl-2 in immortalized rat proximal tubular cells (IRPTCs) cultured under normoxic or hypoxic conditions. The researchers used 1μg of total RNA in the reverse transcription reaction. Qiagen’s QuantiTest CYBR Green PCT Kit was used to quantify PCR products. Promega’s terminal deoxynucleotidyl transferase (TdT) was also used for TdT-mediated dUTP nick end labeling (TUNEL) assays on the cells. The TUNEL-stained cells were analyzed by FACS analysis. Data from these experiments was expressed as percent apoptotic cells.  (2849)

Kennedy, G.C., Matsuzaki, H., Dong, S., Liu, W.M., Huang, J., Liu, G., Su, X., Cao, M., Chen, W., Zhang, J., Liu, W., Yang, G., Di, X., Ryder, T., He, Z., Surti, U., Phillips, M.S., Boyce-Jacino, M.T., Fodor, S.P. and Jones, K.W.

Notes: Terminal Deoxynucleotidyl Transferase was used to biotin end-label PCR products generated from adaptor-ligated genomic DNA fragment templates. The labeled probes were then hybridized to microarrays spotted with SNP alleles. The Terminal Deoxynucleotidyl Transferase reaction was performed for 4 hours at 37°C using 15-20 units TdT, TdT reaction buffer and 18μM biotin-ddATP.

J. Biol. Chem. 275, 8772-8778. Chaperones Hsp70 and Hsp40 suppress aggregate formation and apoptosis in cultured neuronal cells expressing truncated androgen receptor protein with expanded polyglutamine tract. 2000

Kobayashi, Y., Kume, A., Li, M., Doyu, M., Hata, M., Ohtsuka, K., Sobue, G.

Notes: The DeadEnd™ Colorimetric Apoptosis Detection System was used to detect apoptosis in transfected Neuro 2a cells. The cells were transfected with truncated androgen receptors that aggregate in either the nuclei or the cytoplasm. The cells with nuclear aggregates were apoptotic and those with cytoplasmic aggregates were mostly nonapoptotic. The location of the aggregates was determined with GFP fusions. The basic protocol of the DeadEnd™ Colorimetric Apoptosis Detection System was modified to use streptavidin-Texas Red® for fluorometric detection rather than colorimetric detection. Good detail is provided for the modifications. Neuro 2a cells expressing the aggregating AR mutations as well as various chaperonins were analyzed for cell viability at 24, 48 and 72 hours with the CellTiter 96® AQueous One Solution (MTS/PES). The name of the DeadEnd™ Colorimetric Apoptosis Detection System has been changed to DeadEnd™ Colorimetric TUNEL System. (0913)

Notes: Anti-Human BDNF pAb and Anti-Human NT-4 pAb were used for fluorescent immunohistochemical localization of the respective factors to hair follicles of mice. Cryostat sections (8µm thickness) were probed with 1:50 dilutions of the antibodies. Serial sections were also probed with end-labeled probes for BDNF mRNA and TrkB mRNA. The ISH probes were produced using Terminal Deoxynucleotidyl Transferase. (1432)
