Figure S5, Related to Figure 7 and Discussion. NSD2 Is a General Oncoprotein and Not
Involved in the Classical Tumor-Suppressive DNA Damage Response Pathways
(A) H3K36 and H4K44 are highly similar in sequence. Alignment of amino acid sequences flanking
H3K36 and H4K44. H3K36 and H4K44 are highlighted in blue.
(B) Model for how NSD2 H3K36 dimethylation activity contributes to oncogenic programming. Top
Schematic: Normal expression of NSD2 (t(4;14)-negative cells) results in appropriate binding of NSD2 to
physiologic target genes (Class I) and subsequent dimethylation at H3K36 throughout the transcribed
body, with TSS-proximal nucleosomes being most heavily enriched with H3K36me2. This activity is
associated with expression of Class I genes, which in the case of plasma cells, regulate normal B cell
physiologic pathways. In the t(4;14)-negative cells, a number of genes that can promote oncogenesis
(Class II, e.g. c-Met) are not active. Bottom Schematic: Pathologic NSD2 overexpression due to the
t(4;14) translocation overwhelms the mechanisms involved in proper targeting of NSD2 and results in
aberrant and deregulated dimethylation at H3K36 throughout the genome. The efficiency of Class I gene
transcription is diminished and Class II genes are inappropriately activated. The combined action of
lower Class I transcription coupled to increased expression of Class II genes selects for a gene expression
program that is favorable for myelomagenesis. This mechanism could also contribute to onogenic
programming in diverse cancer types. Red flags represent H3K36me2.
SUPPLEMENTAL EXPERIMENTAL PROCEDURES
Reagents, Plasmids, and Antibodies
The cloning of full-length NSD2, NSD2SET and isoform REIIBP was based on NCBI
sequence NM_001042424.2. NSD2SET was amplified by the primer pairs 5’-
CGCGGATCCAAAAACGCATTGCAAG-3’/5’-CGCCTCGAGTTACTATTTGCCCTCTG-3’.
REIIBP was amplified using the primer pairs: 5’-
CTGGGATCCATGATGCGGTGTGTCCGCTGC-3’/5’-
CGCCTCGAGTTACTATTTGCCCTCTG-3’. NSD2SET and REIIBP PCR fragments were
cloned into pGEX-6-P1 using BamHI/XhoI sites. H4 tail library was generated by cloning the
oligos corresponding to H4 amino acids 1-40 with all the lysines replaced by arginines into
pGEX-6-P1(GE Healthcare). Each arginine was restored back to lysine by site-direct
mutagenesis. Full-length NSD2 cDNA was cloned into pCAG-FLAG for overexpression in 293T
cells; pMSCV vectors with 3X-FLAG-MYC epitopes for retroviral transduction of HT1080
cells; and pENTR3C/pDEST20 (Invitrogen) for the purification of recombinant full-length
NSD2 from Sf9 cells. For lentiviral transduction, full-length NSD2 was cloned into
pENTR3C/pLenti6.2/V5-DEST (Invitrogen), and viral particles were prepared with packaging
plasmids pCMV∆8.91 and pMD.G. NSD2 mutants were generated by site-directed mutagenesis
(Stratagene). The luciferase-GFP cassette (a gift from Dr. C.G. Fathman (Stanford University))
was subcloned into pENTR3C and recombined into pLenti6.2/V5-DEST/puromycin (Cordero
Lab, Stanford University) for lentiviral transduction. Antibodies used in the study were: H3,
H3K4me2, H3K9me2, H3K36me1, H3K36me3, H4K20me1, H4K20me2, H4K20me3 (Abcam);
H3K36me3 (Cell Signaling); H3K36me2, H3K27me2, H3K4me3 (Active Motif); H3K27me3
(Millipore); FLAG(M2) (Sigma); GFP (Enzo Life Sciences).
In Vitro Methylation Assays
Methylation assays were performed as described (Shi et al., 2007) using 1 g
recombinant or purified nucleosomes or 1 g of recombinant histone.
Cell Culture and Transfection
KMS11, TKO and modified TKO cells were cultured in RPMI1640 supplemented with
10% fetal bovine serum (ATCC), glutamine (Gibco) and penicillin/streptomycin (Gibco). 293T,
HT1080, U2OS and p19ARF-/-
MEFs were cultured in DMEM with 10% fetal bovine serum and
supplements. H929, KMS12PE, U266 and RPMI8226 were kept in RPMI1640 containing 10%
newborn calf serum (Gibco) and supplements. Transfection of plasmid DNA was performed
using TransIT-LT1 or TransIT-293 (Mirus) following the manufacturer’s protocol. HT1080 and
U2OS were transfected with siRNA targeting NSD2 transcripts using Dharma-FECT
(Dharmacon) transfection reagent. p19ARF-/-
MEFs were a gift from S. E. Artandi (Stanford
University). For growth curve analysis, cells were plated in triplicate and counted every 2 days
after seeding.
Baculovirus Expression of Full-Length NSD2
Generation and purification of recombinant full-length NSD2 were performed following
the manufacturers’ manuals (Invitrogen). In short, pDEST20-NSD2 was utilized to transform
DH10Bac E. coli to obtain shuttle bacmid. Sf9 cells were transfected with bacmid DNA to
produce baculovirus particles and the virus titer was amplified through multiple rounds of
transduction. Log-phase Sf9 cell culture (106/mL) was transduced with virus stock and cells were
harvested 2 days after transduction. The GST-tagged recombinant proteins were purified using
glutathione-conjugated agarose (Amersham), and the quality of the purified proteins was
monitored by SDS-PAGE followed by Coomassie staining.
Purification of Recombinant Full-Length NSD2 in Mammalian Cells
HT1080 cells transduced with pMSCV-FLAG-MYC-NSD2 or control vector were
generated. Whole cell extract was prepared using buffer A containing 50mM Tris-HCl (pH7.4),
250mM NaCl, 0.5% Triton X-100, 10% glycerol, 1mM PMSF. Full-length NSD2 was affinity-
purified with anti-FLAG(M2)-conjugated agarose (Sigma) and eluted with 0.4mg/ml FLAG
peptides for in vitro methylation assays.
RNAi Knockdown Strategy
Oligos targeting NSD2 or SETD2 SET domain were synthesized and cloned into
pLentiLox3.7 to generate lentivirus particles for stable transduction. The two shRNAs target
NSD2 transcripts at 5’-GGACATCAGAAAGGGAGAATT-3’ (shRNA#1) or 5’-
GGAAACTACTCTCGATTTATG-3’ (shRNA#2). SETD2 shRNA targets 5’-
GAGAGGTACTCGATCATAAAGAGTT-3’ at SETD2 transcript. Transduced KMS11 cells
were selected with 10ug/mL puromycin. The two siRNAs targeting the SET domain of NSD2
transcripts, siRNA#1: 5’-GCACACGAGAACGACATCA-3’ and siRNA#2: 5’-
CCACTTCTACATGCTCA-3’, were applied to deplete NSD2 in HT1080 and U2OS cells.
Quantitative Mass Spectrometry
Acid-extracted total histones were subjected to chemical derivatization using D0-proionic
anhydride followed by digestion with trypsin at a substrate:enzyme ratio of 10:1 for 6 hours at
37°C as previously described (Plazas-Mayorca et al., 2009). For comparative analysis of both
KMS11 and TKO2, we then performed a second round of propionylation on the digested
peptides, with one sample being derivatized with the same D0-propionic anhydride reagent and
the other sample being derivatized with D10-propionic anhydride for quantitative proteomics as
previously described (Plazas-Mayorca et al., 2009). Using D10-propionic anhydride introduces a
5 Da shift by derivatization of the free N-termini of all peptides generated from the trypsin
digest. Equal amounts of both samples as quantified by a Bradford assay were mixed together,
and digested peptides were desalted using homemade STAGE tips as reported earlier (Rappsilber
et al., 2003) Desalted peptides were loaded onto fused silica microcapillary column (75mm)
packed with C18 rein constructed with an ESI tip through an Eksigent AS-2 autosampler
(Eksigent Technologies Inc.) at a rate of 200 nL/min. Peptides were eluted using a 5-35% solvent
B in 60 minute gradient (solvent A= 0.1 M acetic acid, solvent B = 70% acetonitrile in 0.1 M
acetic acid) Nanoflow LC-MS/MS experiments were performed on an Orbitrap mass
spectrometer (ThermoFisher Scientific) taking a full mass spectrum at 30,000 resolution in the
Orbitrap and 7 data-dependent MS/MS spectra in the ion trap. All MS and MS/MS spectra were
manually verified.
Chromatin Immunoprecipitation (ChIP) Analysis
ChIP was performed using the corresponding antibodies and protein A-conjugated
magnetic beads (Invitrogen). Briefly, cells were cross-linked with 1% formaldehyde and lysed
with the buffer containing 50mM Tris-HCl pH 8.0, 10mM EDTA, 1% SDS and protease
inhibitors. Cell lysate was sonicated with Branson Digital Sonifier (Branson) and diluted with
RIPA buffer by 10 fold (v/v) before incubating overnight with antibody/protein A-magnetic bead
complexes. In the next day, beads were washed three times with RIPA buffer and twice with TE
buffer. IPed DNA was eluted from beads, de-crosslinked at 68 C and purified using the
MinElute PCR Purification Kit (Qiagen). Purified DNA was subject to ChIP-sequencing analysis
or quantitative real-time PCR analysis. For RT-PCR analyses, purified ChIP DNA was analyzed
on LightCycler 480 (Roche) using SYBR Green Master Mix (Roche) following the
manufacturer’s manual. All samples were normalized to input as control. Sequences of primer
pairs used in the study are listed below.

Reference Gene Sets
We used the human reference genome hg18 and RefSeq annotation with in total 34,237
genes. Among the 48,802 probe sets on the gene expression array (HumanHT-
12_V3_0_R2_11283641_A), 27,456 probe sets could be mapped to 20,910 high confidence
protein-coding (Accessions starting from “NM”) RefSeq genes, which were selected for
downstream analysis. The remaining 13,327 RefSeq genes are either low confidence genes or
Unigenes that lack exact gene structure.
H3K36me2 ChIP-Seq Data Analysis
In total, 130,438,736 raw reads were generated using Illumina Genome Analyzer II single
end sequencing protocol from six samples, including input materials from KMS11 and TKO2
cells and two biological replicates of H3K36me2 ChIP DNA. 48.09% of the raw reads passed
quality filtering and were uniquely mapped to the human genome using Illumina Eland software,
allowing up to 2 mismatches. Average size of ChIP-DNA fragment in each sample was
estimated by cross-strand Pearson correlation. The 5’ end of each uniquely mapped and high-
quality read was shifted half fragment size toward 3’ end, and then extended 50bp to both
directions. H3K36me2 signal intensity at each nucleotide was calculated as read coverage,
followed by scaling normalization to ensure that the average intensity across the whole genome
equals to 1 for each sample. The input intensity was subtracted from the ChIP signal based on a
Poisson model:
where st is the ChIP intensity and Si is the input intensity, St-c is the resulting ChIP intensity after
input subtraction, b is the background value provided as a parameter for normalization, and is set
to 1 in this work. Average profiles of H3K36me2 across gene body were all derived from these
input-subtracted and normalized intensity profiles.
Analysis of Multiple Myeloma Patient Datasets
Expression datasets of Multiple Myeloma Research Consortium (MMRC) patient
samples were downloaded from http://www.broadinstitute.org/mmgp/home. Genes whose
transcript levels correlated with NSD2 expression were identified using Pearson correlation
coefficient >0.3 (positively correlated) or <-0.3 (negatively correlated). p-values calculated by
Fisher’s exact test were used to measure the statistical significance of the overlaps between gene
lists. The heatmap shown in Figure S34 was plotted by Mev_4_4 (v10.2). Hierarchical clustering
was performed based on Pearson correlation and average linkage.
Real-Time PCR Gene Expression Analysis
RNA samples were extracted from cells using RNeasy Plus kit (Qiagen) and reverse
transcribed into cDNA using the SuperScript III First Strand Synthesis System (Invitrogen).
Quantitative real-time PCR analysis was performed on a Roche LightCycler 480 using the
manufacturer’s Universal Probe Library system. The primer sequences and the corresponding
fluorecein-labeled probes (Roche) are listed below.
