Disruption of Tefm in the germline and heart.Figure 1Targeting strategy for disruption of the Tefm gene. LoxP sites flanking exon 2 of the Tefm gene together with puromycin selection marker (PuroR) were inserted into the mouse genome by homologous recombination. The PuroR cassette was excised by mating with Flp-recombinase mice to obtain heterozygous floxed Tefm mice (Tefm+/loxP). Whole-body and tissue-specific Tefm knockout mice were obtained by crossing Tefm+/loxP with different Cre-recombinase mice.

Figure 5GUARDIN acts as an RNA scaffold to facilitate interaction between LRP130/PGC1α that acts to transcriptionally repress FOXO4 expression. This repression prevents FOXO4-mediated upregulation of p21 and cell entry into senescence. GUARDIN participates in rapamycin-induced cellular senescence, likely through downregulation by FOLS2, which is also downregulated by rapamycin.

Figure 3The nuclear localization of Rfa1 proteins is altered in rtt105∆ mutant cells. Rfa1 tagged with GFP at its C terminus was used to analyze the localization of Rfa1-GFP fusion protein (Green) and the nuclear envelop is visualized with the Nup49-mCherry fusion protein (Red) using fluorescence microscopy. DIC: differential interference contrast. Scale bar: 5μm. NLS-RFA1-GFP rescues the nuclear localization of Rfa1 in rtt105∆ mutant cells. The wild type RFA1 gene was fused with an SV40 large T Antigen nuclear localization sequence (NLS) at its 5'-end and a GFP gene at its 3' end to obtain a construct, driven by the RFA1 promoter to express NLS-RFA1-GFP fusion protein. The engineered construct was then transformed into WT or rtt105∆ mutant yeast cells to replace its endogenous RFA1 expression. The resulting yeast cells were then visualized under microscope, and GFP signals enriched in the nuclei were scored. RFA1-GFP lacking the NLS sequence was transformed into rtt105∆ rfa1∆ mutant cells as a control. DAPI staining indicates nuclear DNA.

Statistical significance was evaluated based on Student's t-tests (*: 0.01≤P value<0.05).

Figure 3Treatment with UDCA (13 mg/kg/d) and GSH (40 mg/kg/d) for 2 weeks restored normal liver function in the child. However, when the treatment was ceased the levels of serum ALT, AST and TBA returned to abnormally high levels in the patient. Interestingly, treatment with half of the dose of UDCA and GSH also maintained the normal levels of serum ALT and AST, and reduced serum TBA in the child patient.
Figure 4A SGO2 localizes at the centromeres of spermatocyte-derived and maternal chromosomes. Oocytes were fixed at metaphase I and stained for SGO2 (green), ACA (centromeres, magenta), and Hoechst33342 (DNA, blue).
