Developing effective debugging strategies to guarantee the reliability of software is important. By analyzing the debugging process used by experienced programmers, we have found that four distinct tasks are consistently performed: (1) determining statements involved in program failures, (2) selecting suspicious statements that might contain faults, (3)(More)
E6 and E7 oncoproteins from high-risk human papillomavirus (HPV) can transform cells in tissue culture and induce tumors in vivo by abrogating the cell-cycle checkpoint. To investigate the impact of HPV16 E6 and E7 on the cell-cycle regulatory machinery in oral epithelial cells, normal human oral epithelial cells were transfected with HPV16 E6 and E7 open(More)
Most studies of software failures and faul ts have done little more than classifying failures and faults collected f r o m long-term projects. In this paper, we propose a model t o analyze failures and faults f o r debugging purpose. In the model, w e define ‘ ya ihre modes” and “failure types” t o ident i fy t he existence of program failures and the(More)
The secondary structures in mRNA often cause early termination during the synthesis of cDNA. In an attempt to determine the 5'-untranslated region (UTR) of the gene LIP1 using the RNA ligase-mediated rapid amplification of cDNA ends (RLM-RACE), we found that reverse transcriptases skipped over the LIP1 RNA secondary structures and continued the DNA(More)
Lapatinib is an oral, small-molecule, dual tyrosine kinase inhibitor of epidermal growth factor receptors (EGFR, or ErbB/Her) in solid tumors. Little is known about the effect of lapatinib on leukemia. Using human chronic myelogenous leukemia (CML) K562 cells as an experimental model, we found that lapatinib simultaneously induced morphological changes(More)
Profilins are small proteins essential for many normal cellular dynamics and constitute one of the crucial components of actin-based cellular motility. Several recent studies have implicated a role for the profilin (PFN) family in cancer pathogenesis and progression. However, their expression and promising functions are largely unknown in oral squamous cell(More)
Cisplatin (CDDP) is an important anti-cancer drug commonly used in various human cancers, including nasopharyngeal carcinoma (NPC). How to overcome the drug resistance of CDDP provides opportunities to improve clinical outcomes of NPC. O(6) -methylguanine-DNA methyltransferase (MGMT) has been well-characterized to be a therapeutic determinant of O(6)(More)
