ObjectiveTo explore the regulatory effect of Pien Tze Huang (PZH) on targeting partner of NOB1 (PNO1) and it’s down-stream mediators in colorectal cancer (CRC) *** polymerase chain reaction was performed to determine mRNA levels of PNO1, TP53, and CDKN1A. Western blotting was performed to determine protein levels of PNO1, p53, and p21. HCT-8 cells were transduced with a lentivirus over-expressing PNO1. Colony formation assay was used to detect cell survival in PNO1 overexpression of HCT-8 cells after PZH treatment. Cell-cycle distribution, cell viability and cell apoptosis were performed to identify the effect of PNO1 overexpression on cell proliferation and apoptosis of HCT-8 cells after PZH treatment. Xenograft BALB/c nude mice bearing HCT116 cells transduced with sh-PNO1 or sh-Ctrl lentivirus were evaluated. Western blot assay was performed to detect PNO1, p53, p21 and PCNA expression in tumor sections. Terminal deoxynucleotidyl transferase dUTP nick end labling (TUNEL) assay was used to determine the apoptotic cells in *** treatment decreased cell viability, down-regulated PNO1 expression, and up-regulated p53 and p21 expressions in HCT-8 cells (P<0.05). PNO1 overexpression attenuated the effects of PZH treatment, including the expression of p53 and p21, cell growth, cell viability, cell cycle arrest and cell apoptosis in vitro (P<0.05). PNO1 knockdown eliminated the effects of PZH treatment on tumor growth, inhibiting cell proliferation inhibition and apoptosis induction in vivo (P<0.05). Similarly, PNO1 knockdown attenuated the effects of PZH treatment on the down-regulation of PNO1 and up-regulation of p53 and p21 in vivo (P<0.05).ConclusionThe mechanism by which PZH induces its CRC anti-proliferative effect is at least in part by regulating the expression of PNO1 and its downstream targets p53 and p21.

西汉敦煌郡阳关、玉门关的命名与设置布局应是仿照中原关隘布局而来的,即复制或者移植了中原地区的关隘名称与布局。而悬泉汉简所载“敦煌塞”很可能就是指阳关一带的边塞,也即阳关都尉所辖边塞。阳关是西汉中原前往西域地区使用最多的关隘。西汉敦煌郡九置组成的邮驿系统向东可通达长安,向西从最西端的龙勒置就近经由阳关出塞,又经文候鄣可抵达鄯善国伊循城,至此连接西域南道。这条阳关通道相对玉门关通道更便于通行,因而,阳关通道是文书传送之路,也是戍卒、施刑士来往之路,还是西汉与西域间通使、通商之路。因此,阳关应当是为了与西域诸国通使通商需要而设置的关隘,此后成为西汉中原与西域交流交往交融的一扇大门。
