Although a recent meta-analysis of 109 studies and 531 unique cases of craniopharyngioma found that patients who underwent subtotal resection and did not receive radiation therapy had a worse outcome than patients who underwent gross-total resection or those who had subtotal resection and were also treated with radiation therapy, 4 a decision was made to follow up our patient with serial MRI and to initiate radiation therapy only if there were concerns of recurrence. This was based. ...

Henrietta Lacks (1920 - 1951) was an African-American woman who passed away of cervical cancer in 1951. Little did she know that her fatal tumors would hold a key to numerous medical advancements (polio vaccines and chemotherapy for example). Her biopsied cells were found to really thrive outside her body and would be used to create the first immortal cell line for medical research so that her cells are still alive today - over 60 years after her passing. Her cells were used to create the so called HeLa cell line for scientific research - currently the oldest and most commonly used human cell line. They were also the first human cells successfully cloned in 1955.. Henriettas cells have been mailed to scientists around the globe for research and scientists have grown some 20 tons of cells. Henrietta is still living today, around the globe and bigger than ever. Find out more by listening Radiolabs great short story about the subject!. ...

Background aims. Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorders (PTLD) belong to the most dreaded complications of immunosuppression. The efficacy of EBV-specific T-cell transfer for PTLD has been previously shown, yet the optimal choice of EBV-derived antigens inducing polyclonal CD4þ and CD8þ T cells that cover a wide range of human leukocyte antigen types and efficiently control PTLD remains unclear. Methods. A pool of 125 T-cell epitopes from seven latent and nine lytic EBV-derived proteins (EBVmix) and peptide pools of EBNA1, EBNA3c, LMP2a and BZLF1 were used to determine T-cell frequencies and to isolate T cells through the use of the interferon (IFN)-g cytokine capture system. We further evaluated the phenotype and functionality of the generated T-cell lines in vitro. Results. EBVmix induced significantly higher T-cell frequencies and allowed selecting more CD4þIFN-gþ and CD8þIFN-gþ cells than single peptide pools. T cells of all specificities ...

Five immortal cell lines derived from a Li-Fraumeni syndrome patient (MDAH 087) with a germline mutant p53 allele were characterized with respect to telomere length and genomic instability. The remaining wild-type p53 allele is lost in the cell lines. Telomerase activity was undetectable in all immortal cell lines. Five subclones of each cell line and five re-subclones of each of the subclones also showed undetectable telomerase activity. All five immortal cell lines exhibited variability in the mean length of terminal restriction fragments (TRFs). Subclones of each cell line, and re-subclones of the subclones also showed TRF variability, indicating that the variability is owing to clonal heterogeneity. Chromosome aberrations were observed at high frequencies in these cell lines including the subclones and re-subclones, and the principal types of aberrations were breaks, double minute chromosomes and dicentric chromosomes. In addition, minisatellite instability detected by DNA fingerprints was ...

Which method should be used?Some investigators found EIA to be more sensitive than IFA, particularly the anticomplement immunofluorescence technique (22); others found the EIA technology to be as sensitive as IFA or even more sensitive than EIA (23, 27). Already in the mid-1980s the results of assays performed with the first generations of EIAs correlated nicely with those of IFA with purified VCA and EBNA proteins as antigens (9). EIA performance characteristics strongly depend on the nature of the antigens and the preparation and the selection of antigens used (14). As a consequence, the differences in performance characteristics observed between IFA and EIA (i.e., relative sensitivity, relative specificity, and predictive values) are due to the use of various different forms and different selections of antigens with the EIA and to the different IFA substrates used (i.e., different prototype-derived EBV-transformed cell lines [e.g., Raji cells instead of P3HR-1 cells] for detection of ...

Studies have shown that wild-type hTERT protein can functionally replace the HPV-16E6 protein, which cooperates with the viral E7 protein in the immortalization of primary keratinocytes. Previously, we made the surprising finding that catalytically inactive hTERT (hTERTci), elongation-defective hTERT (hTERT-HA), and telomere recruitment-defective (hTERT N+T) also cooperate with E7 in cell immortalization, indicating that hTERT has immortalizing activities independent of its telomere maintenance functions. Since reports show an hTERT role in gene activation, we performed microarray studies to discover that E6, hTERT and hTERT mutated proteins altered the expression of highly overlapping sets of cellular genes. Pursuing in-depth studies of these targets shared by E6 and hTERT, we focused on AIB1, a nuclear coactivator known to be elevated in some cancers, and BMI1, the core subunit of the Polycomb Group Repressor Complex (PRC) 1 which is known to play a role in immortalization and determining cell ...

Last week, we finished our Ask the Expert Discussion on Cell Line Authentication. Inadvertent cell line contamination is a serious concern for many researchers. Failure to monitor cell lines for contamination may result in compromised data. Current estimates are that 18% to 36% of all active cell lines are either cross-contaminated or misidentified.1
