MiR-122 targeted <t>PKM2</t> and suppressed PKM2 expression. (A) Seed sequence of miR-122 in the 3UTR of PKM2 was underlined. WT and mutated sequences of PKM2 were inserted into pmiRGLO luciferase vector. (B) Re-expression of miR-122 suppressed luciferase activity of the WT but not the Mut 3UTR of PKM2. EV and sensor sequences served as negative and positive controls, respectively. (C) Re-expression of miR-122 in SMMC-7221 and MHCC-97L cells suppressed PKM2 but not <t>PKL/R</t> expression. (D) Linear regression model demonstrated that PKM2 mRNA expression was inversely correlated with miR-122 expression in HCC (pink) and NT liver tissues (blue). (E) Expression levels of 667 miRNA species in HCC and NT were plotted. Each dot represents one individual miRNA. MiR-122 is the most abundant miRNA in NT liver.

PKM2 expression in human HCC. (A) mRNA expression of PKL, PKM1, and PKM2 in HCC and NT tissues. Values = 2 ΔΔCT , ΔΔCT = (CT PK – CT HPRT ) of HCC - (CT PK – CT HPRT ) of NT. P values, Wilcoxin signed rank test (B) Waterfall plot shows that, at the mRNA level, PKM2 was up-regulated (HCC/NT2 folds) in 29/60 (48.33%) human HCC samples. (C) Representative pictures of IHC staining with antibody against PKM2 in HCC tissue microarray. PKM2 protein was drastically up-regulated in human HCCs as compared to the paired NT tissues. (D) Mann Whitney test showed that PKM2 over-expression was associated with multiple aggressive clinicopathological features in HCC including the presence of tumor microsatellites, presence of venous invasion, and absence of tumor encapsulation. (E) Over-expression of PKM2 in human HCC was associated with poor prognosis. HCC patients were categorized into two groups: PKM2 over-expression and PKM2 normal/under-expression. PKM2 was considered to be over-expressed when HCC/NT2 folds and was considered to be normal/under-expressed otherwise. HCC patients with PKM2 over-expression had a higher 1-year tumor recurrence rate after surgical resection than HCC patients without PKM2 over-expression, 46.667% Vs 25%. (F) Patients with PKM2 over-expression had lower 5-year overall survival rates after surgical resection. P values were calculated by Kaplan-Meir log rank test.

    LUX and ELF3 Affect Circadian Output to Seeds. (A) Relative DOG1 expression in seedlings under free-running conditions. Seedlings were grown under 12 h light/12 h dark for 6 d followed by CL illumination for 24 h. Samples were harvested every 4 h from ZT24. (B) Relative DOG1 expression in developing siliques. Plants were grown under LD conditions, and siliques (6 d after pollination) were harvested every 4 h started from ZT0. (C) Seed germination rate. Col-0, lux , and elf3 plants were grown under LD conditions for 3 weeks and transferred to CL or kept at LD until seed maturation. Germination of freshly harvested seeds in the light was analyzed. (D) Relative DOG1 expression in developing siliques. Plants were grown under LD conditions, and siliques (8 d after pollination) were harvested at ZT8. For (A) , (B) , and (D) , data are the average ± SD of three biological replicates. (E) A working model illustrating the roles of PKL and EC in controlling seed dormancy. LUX binds directly to a specific DNA sequence of DOG1 and recruits PKL to the DOG1 locus through their physical interaction. This interaction increases H3K27me3 levels on DOG1 chromatin, thereby repressing its transcription and leading to reduced seed dormancy. Arrow indicates positive regulation and bar denotes negative regulation.
