Abstract 827: Statistical analyses of stable housekeeping gene expression in cancer post-irradiation
No full textAbstract
Ionizing radiation (IR) can induce DNA damage in human cells and result in changes in gene expression. The changes could also include some of the commonly used housekeeping genes (HKG), and thus making them unstable over the time period after being exposed to radiation. Normalization of housekeeping genes is critical for understanding gene expression post-irradiation. Toward the validation of stable HKGs, cancer cell lines from head and neck, non-small cell lung and pancreas were irradiated to 2, 4 and 6 Gy IR doses. Statistical analysis of RNA expression of fourteen HKGs measured at 5 min to 48hrs post-irradiation reveal tradition HKGs such as beta-actin (ACTB) and glucose-6-phosphate-dehydrogenase (G6PD) to be unstable, while TATA-Box Binding Protein (TBP) and Importin 8 (IPO8) was identified as stable HKGs in non-small lung and pancreas cell across all IR doses and time. Interestingly in head and neck cancer, TBP is also found stable across all IR doses and time. The statistical framework used for identification and validation of HKGs can serve as a reliable metric for quantifying gene expression post-irradiation.

ASIP data-plane processor for multi-standard wireless protocol processing
No full textEvolving Multi-Protocol Multi-Band Software Defined Radio (SDR) devices aim at supporting multiple protocols seamlessly and efficiently. The design of such radios necessitates flexibility in physical layer processing, flexibility in routing packets through processing engines and flexibility in radio frequency reception/transmission. This dissertation addresses an efficient implementation of flexible physical layer processing (PHY) for Interleaving, De-Interleaving and linear Minimum Mean Square Error (MMSE) detection in Multiple Input Multiple Output (MIMO) receivers through Application Specific Instruction Set Processors (ASIPs). The thesis defines and develops a WINLAB cognitive radio (WiNC2R) compatible data-plane ASIP architecture along with suitable hardware-software partitioning of the Processing Engine unit. Given the requirement of very significant design time and the lack of the flexibility after design, dedicated ASIC for PHY may not be a viable option although it has the best performance among all available options. The software application running on general purpose processor cannot satisfy the throughput requirements of the wireless standards. ASIPs provide a better trade-off between flexibility and performance, with the advantage of considerably lower design time than ASICs. We design an efficient multi-standard (802.11a, 802.16e/m) supporting Interleaver/De-Interleaver ASIP, satisfying the throughput requirements for all the modulation-schemes/data-rates in both of the standards. It can be programmed to scale for supporting future wireless standards (that use Block Interleaving/De-Interleaving). We also study viability of a flexible MIMO MMSE detector ASIP supporting variable MR (Number of receiving antennas) * MT (Number of transmitting antennas) operations. We have analyzed the implementation of an hardware-centric algorithm for MIMO detection on an ASIP and also improved its performance with the help of techniques such as fixed point implementation, Single Instruction Multiple Data (SIMD) and Very Long Instruction Word (VLIW). Analysis of the design performance results for MIMO ASIP indicates the limitations of hardware-implementation-specific algorithms on ASIP. We also provide the account of design decisions such as custom ports, memory interfaces and registers that are added to the data-plane processor ASIPs in order to substitute them for dedicated hardware engines in the WiNC2R platform.M.S.Includes bibliographical referencesby Mohit Gopal Wan

Wilson (1982), Subrahmanyan Chandrasekhar (1983), William A. Fowler (1983), Carlo Rubbia (1984), Simon van der Meer (1984), and Klaus von Klitzing (1985) indicated high variations: No. of Synchronous References ranged from 24 (Meer) to 283 (Siegbahn); Synchronous Self-References ranged from 5 (Rubbia) to 88 (Siegbahn); synchronous references to others ranged from 10 (Chandrasekhar) to 255 (Wilson); Synchronous Self-Reference Rates ranged from 6.66 % (Rubbia) to 65.51 % (Chandrasekhar); Single-Authored References ranged from 15 (Klitzing) to 160 (Wilson); Multi-Authored References ranged from 4 (Chandrasekhar) to 194 (Siegbahn); Collaboration Coefficient in the synchronous references ranged from 0.14 (Chandrasekhar) to 0.75 (Klitzing); and Recency (age of 50 % of the latest references) ranged from 2 (Klitzing) to 18 (Chandrasekhar) years. Seventy five per cent of the references belonged to journal articles. Highly referred journals were Astrophysical Journal, Physical Review B, Physical Review Letters, Arkiv Fuer Fysik, Surface Science, Physics Letters, and IEEE Transactions on Nuclear Science.

Abstract 4121: Androgen receptor as a potential target in non-small cell lung cancer
No full textAbstract
The cancer genome atlas (TCGA) has identified androgen receptor (AR) to be mutated, deleted and amplified across human lung squamous cell carcinoma and adenocarcinoma. Expression of AR is critical for early lung development. However, the intriguing expression of AR in non-small cell lung cancer (NSCLC) opens up an alternative treatment paradigm in the event of onset of clinical resistance to lung cancer drugs. To investigate this potential, a) 10 NSCLC cell lines and 3 control prostate cancer cell lines were stimulated with synthetic AR agonist, R1881 at 24, 48 and 72 hours. 0.5-4-fold RNA and protein expression was found across these lung cancer cell lines when compared to unstimulated cells. b) droplet digital PCR revealed varying copies of AR DNA when benchmarked to prostate AR. c) cell proliferation assays of these cell lines with enzalutamide (MVD3100) treatment resulted in 50-65% cell survival at concentrations ranging from 10 - 25 µM. d) Immunohistochemical staining of AR in a NSCLC human tissue microarray (TMA) revealed 10 out of 88 patients (11%) to have AR positive staining in their tumor. This included 6 adenocarcinomas and 2 squamous cell carcinomas. 8 patients had focal while 2 had diffuse staining. Validation of the TMA performed with whole mount slides confirmed diffuse staining in these 11 samples. Taken together, these findings suggest AR is a potential therapeutic target in NSCLC and further work is underway to test these observations in drug resistant lung cancer cell lines and pre-clinical mouse models.
