Title: Use for regulating specific transcriptional activity by HDAC2 during TPA-induced HL-60 cell differentiation
Inventor: SEO SANG BEOM
IPC: G01N33/574
Filed: 2019-05-22
Abstract: The present invention relates to a use for regulating the specific transcriptional activity of HDAC2 during a 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced leukemia cell differentiation process. A human myeloid leukemia cell line HL-60 is divided into monocytes when treated with TPA. However, the mechanism of differentiation of the cells relative to TPA has not been clarified. The present inventors performed ChIP-seq profiling of RNA Pol II, HDAC2, Acetyl H3 (AcH3), and H3K27me3, and analyzed differential chromatin state changes during TPA-induced differentiation of HL-60 cells. The present inventors focused on anomalous activated genes that appear to have improved H3 acetylation despite increased HDAC2 collection. The present inventors found that HDAC2 positively regulates the expression of the genes in a histone deacetylase activity-independent manner. In conclusion, the present invention found a specific-chromatin state during HL-60 cell differentiation after TPA exposure and found that HDAC2 can activate transcription of specific genes through interaction with PAX5 in a deacetylase activity-independent path.

Title: Electronic devices having low refresh rate display pixels with reduced sensitivity to oxide transistor threshold voltage
Inventor: QIAN CHUANG
IPC: G09G3/3258
Filed: 2019-05-30
Abstract: The present invention relates to an electronic device having a low refresh rate display pixel with reduced sensitivity to an oxide transistor threshold voltage, which reduces abnormal display behaviors. According to the present invention, a display includes an array of organic light emitting diode (OLED) display pixels operated at a low refresh rate. Each display pixel includes a driving transistor coupled to one or more discharge transistors in series and each OLED. To help decrease of leakage during a low refresh rate display operation, a semiconducting oxide transistor can be coupled between drain and gate terminals of the driving transistor. Moreover, a silicon transistor is interposed between the semiconducting oxide transistor and the gate terminal of the driving transistor. One or more capacitor structures are coupled to a source and/or drain terminals of the semiconducting oxide transistor to decrease a rebalancing current flowing through the semiconducting oxide transistor when the semiconducting oxide transistor is turned off. As such configuration, an arbitrary discharge current flowing through the OLED may not be sensitive to an arbitrary potential drift in threshold voltage of the semiconducting oxide transistor.
