Increased 18F-FDGuptake on PET in hepatocellular carcinoma is associated with level ofPDL1 expression that regulated by beta-catenin
Conclusion: The above results demonstrate that 18F-FDG PET/CT is closely related to the expression of PDL1 in HCC, and it is an important criterion that not only predicts the anti-cancer response of anti-PDL1 immunotherapy through that 18F-FDG PET/CT but also reflects the prognosis Research Support: This work was supported by a National Research Foundation of Korea (NRF) grant funded by the Korean government (MSIP) (No. NRF-2011-0030086) and and was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIP) (NRF-2016R1E1A1A01943303) and h was supported by the Basic Science Rese...

hCG activates Epac-Erk1/2 signaling regulating Progesterone Receptor expression and function in human endometrial stromal cells
AbstractSTUDY QUESTIONHow does hCG signal in human endometrial stromal cells (ESCs) and what is its role in regulating ESC function?SUMMARY ANSWERhCG signaling in ESCs activates the extracellular signal-regulated protein kinases 1 and 2 (Erk1/2) pathway through exchange protein activated by cyclic AMP (cAMP) (Epac) and transiently increases progesterone receptor (PR) transcript and protein expression and its transcriptional function.WHAT IS KNOWN ALREADYhCG is one of the earliest embryo-derived secreted signals in the endometrium, which abundantly expresses LH/hCG receptors. hCG signals through cAMP/protein kinase A (PKA) ...

Abstract C81: Identification of novel synergistic targets for rational drug combinations with PI3 kinase inhibitors using siRNA synthetic lethality screening against GBM
In this study, we performed a synthetic lethality screen to identify genes or pathways whose inactivation, in combination with the PI3K inhibitors PX-866 and NVPBEZ-235, might result in a lethal phenotype in glioblastoma multiforme (GBM) cells. We screened GBM cells (U87, U251, and T98G) with a large-scale, short hairpin RNA library (GeneNet), which contains 43 800 small interfering RNA sequences targeting 8500 well-characterized human genes. To decrease off-target effects, we selected overlapping genes among the 3 cell lines that synergized with PX- 866 to induce cell death. To facilitate the identification of potential t...

Abstract 5118: Decursin synergistically enhances TRAIL-induced apoptosis through CHOP dependent DR5 signaling in TRAIL resistant lung cancer cells
Targeting the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), which has been clinically established for anticancer therapy, is the attractive strategy to specifically kill cancer cells through the death receptors. Nonetheless, its therapeutic potential is limited due to the resistance in cancer cells. Thus, in the present study, we evaluated the therapeutic potential of Decursin, a pyranocoumarin isolated from the Korean Angelica gigas root as a TRAIL sensitizer in a variety of resistant lung cancer cells. Co-treatment of Decursin with TRAIL synergistically induced apoptosis in TRAIL resistant lung cancer ...
