In computed tomographic lung cancer screening, both solid and ground glass nodules are regularly encountered. Ground glass nodules may or may not have a solid component and it has been shown that they have a much higher chance of being malignant in comparison to solid nodules. Computer-aided detection (CAD) systems designed for solid nodules perform poorly on detection of ground glass nodules, ...
Solid stress and tissue stiffness affect tumour growth, invasion, metastasis and treatment. Unlike stiffness, which can be precisely mapped in tumours, the measurement of solid stresses is challenging. Here, we show that two-dimensional spatial mappings of solid stress and the resulting elastic energy in excised or in situ tumours with arbitrary shapes and wide size ranges can be obtained via t...
Pancreatic cancer is known as one of the most lethal cancers in the world. A majority of advanced stage pancreatic cancer patients are diagnosed with distant metastasis and given poor prognoses, calling for a better therapeutic option. Mesothelin, which is overexpressed in pancreatic cancer and other solid tumors, is a potential target for pancreatic cancer immunotherapy. Adoptive transfer of T...
Fourteen breast cancer lines (8 human, 5 rat, and 1 mouse) have been studied in terms of their ability to form multicellular tumor spheroids (MTS) with the agar-base method. Only 8 of the lines formed MTS in contrast to a 100% efficiency in a series of 11 varied tumors reported in the initial studies with this method. We have compared the lines that do and do not form MTS in terms of a variety ...
The MEK1 and MEK2 inhibitor GSK1120212 is currently in phase II/III clinical development. To identify predictive biomarkers, sensitivity toGSK1120212was profiled for 218 solid tumor cell lines and 81 hematologic malignancy cell lines. For solid tumors, RAF/RAS mutation was a strong predictor of sensitivity. Among RAF/RAS mutant lines, co-occurring PIK3CA/PTEN mutations conferred a cytostatic re...
A general transcription factor IID which binds to the TATA box promoter element on RNA polymerase II genes regulates and initiates eukaryotic mRNA synthesis. A quantitative polymerase chain reaction procedure was developed and the human transcription factor IID (hTFIID) transcript was measured in normal human tissues, lung carcinomas, lung carcinoma cell lines, and breast carcinomas. In some no...
A general transcription factor IID which binds to the TATA box promoter element on RNA polymerase II genes regulates and initiates eukaryotic mRNA synthesis. A quantitative polymerase chain reaction procedure was developed and the human transcription factor IID (h II III)) transcript was measured in normal human tissues, lung carci nomas, lung carcinoma cell lines, and breast carcinomas. In som...
Early detection is an effective means of reducing cancer mortality. Here, we describe a highly sensitive high-throughput screen that can identify panels of markers for the early detection of solid tumor cells disseminated in peripheral blood. The method is a two-step combination of differential display and high-sensitivity cDNA arrays. In a primary screen, differential display identified 170 ca...
Cancer is being reinterpreted in the light of recent discoveries related to the histone code and the dynamic nature of epigenetic regulation and control of gene programs during development, as well as insights gained from whole cancer genome sequencing. Somatic mutations in or deregulated expression of genes that encode chromatin-modifying enzymes are being identified with high frequency. Nowhe...
The presence of stem cells in leukemia and solid tumors has been demonstrated in recent decades. Cancer stem cells have the potency of tumorigenesis; furthermore, they have the ability of self-renewing and differentiation like other stem cells. They also play important role in the process of tumor invasion and metastasis. Several studies have been performed to discover the spe...
