Supplementary Figure 1 – Flow cytometry profiles indicating the amount of 5dodecanoylaminofluorescein di--D-galactopyranoside (C12FDG) hydrolysed by galactosidase. C12FDG only becomes fluorescent once hydrolysed by -galactosidase,
allowing quantification of -galactosidase activity. Consistent with an expected increase
in the number of senescent cells with passage number, a marked increase in C12FDGFITC signal was observed with increased passages. Importantly, the C12FDG-FITC
signal was higher in Moz-/- cultures as compared to control cultures at all time points
analysed.

Supplementary Figure 2 – Moz mRNA levels in primary MEFs.
No differences in Moz mRNA levels relative to passage number were observed in wild
type MEFs. This suggests the MOZ-HAT complex levels are relatively stable and MOZ
is specifically recruited to chromatin as required. n = 4 independent cultures per time
point. Moz expression levels were standardised to housekeeping genes Gapdh and
Hsp90ab1.

(a) Representative FACS plot showing separation into different phases of the cell cycle:
G0, G1, S, G2 and M, based on Ki67 and DAPI staining. (b-d) Quantification of cells in
the different phases of the cell cycle at (b) passage two, (c) passage four and (d) passage
six. n = 4 wild type, 3 Moz+/- and 5 Moz-/-. * marks a significant difference between the
respective genotypes at p < 0.05.

(a) Primary MEFs were separated based on DNA content via DAPI. (b) Positive control
– MEFs were treated with 80 M H2O2 for 30 minutes to induce double stranded DNA
breaks, before being stained with an antibody against H2A.X. As expected H2O2
treatment led to increased H2A.X levels. (c) Primary MEFs were collected at passage
one, three and five, fixed, stained for H2A.X as an indicator of double stranded DNA
breaks, and analysed by flow cytometry. Consistent with the quantification provided in
Figure 2b, H2A.X profiles do not show differences between the wild type, Moz+/- and
Moz-/- MEFs. n = 5 wild type, 4 Moz+/-, and 3 Moz-/- cultures.
Supplementary Figure 5 – Cell cycle analysis of MEFs cultured at physiological levels
of oxygen (3% O2).
Cell cycle analyses were performed by flow cytometry using DAPI and Ki67 at
passages two, five and eight. The cell cycle profile was normal at passage two, while
there was a decrease in the number of Moz-/- MEFs in the G2/M phase at passages five
and eight, and concomitant increase in G0 and/or G1. n = 5 wild type, 3 Moz+/- and 4
Moz-/- cultures. Asterisks indicate a significant difference between marked genotypes at
*p < 0.05 and **p < 0.01.

Supplementary Figure 6 – Western blot analysis of passage 3 wild type and Moz-/MEFs grown at 20% O2.
Protein levels of senescence marker and mediator p16INK4A were increased as early as
passage 3 in Moz-/- MEFs compared to wild type. In contrast, p15INK4B, p21 and p53
levels were unchanged. Treatment with doxorubicin, which induces DNA damage and
cell death, is provided as a positive control for p53. These data are consistent with
mRNA levels of Ink4a, Arf and p21 in passage 3 MEFs (Figure 4), and Ink4a and Arf
levels in passage 5 MEFs (Figure 1e). n = 4 independent cultures of each genotype.
Actin is provided as a loading control.

Supplementary Figure 7 – Expression analysis of wild type and Moz-/- MEFs.
(a) Moz mRNA was not detected in Moz-/- MEFs (b) Gene expression levels of major
regulators of senescence in wild type and Moz-/- MEFs grown at physiological 3%
oxygen. mRNA levels of genes encoding major inhibitors of senescence that were
decreased in Moz-/- MEFs at 20% O2 (Fig. 5) were also decreased at 3% O2 (here). This
suggests that the reduction in mRNA levels of Cdc6, Skp2, Ezh2, Melk, E2f2 and Nsd2
was independent of DNA damage, which is prevalent in MEFs cultured in 20% O2. (c)
Ink4b mRNA levels in Ink4a-Arf-/-;Moz-/- cells were not different to Ink4a-Arf-/- controls
(d) Ratio of housekeeping genes Hsp90ab1 mRNA to Gapdh mRNA were not different
between wild type and Moz-/- cells at 20% O2. n = 4 independent cultures of each
genotype. Gene expression levels were standardised to housekeeping genes Hsp90ab1
and Gapdh. Asterisks mark statistically significant differences between wild type and
Moz-/- cultures at *p < 0.05, **p < 0.01 and ***p < 0.001.

Supplementary Figure 8 – CDC6 overexpression affords a modest growth advantage
to Moz-/- MEFs. MEFs were virally infected with a Cdc6-GFP vector and control
negative Empty-GFP vector. Infection with a Cdc6-GFP vector lead to a small but
statistically significant increase in Moz-/- cells compared to controls. n = 3 independent
cultures of each genotype. Asterisks mark statistically significant differences between
wild type and Moz-/- cultures at *p < 0.05.
