Extended Data Fig. 1 | BORIS is expressed in several cancers and
associated with high-risk features. a, b, Relative mRNA expression
[log 2 (FPKM + 1)] of CTCF and BORIS in normal tissues (a) and in
various cancer types based on TCGA datasets (b). FPKM, fragments per
kilobase of transcript per million mapped reads. Keys to cancer types:
ACC, adrenocortical carcinoma; AML, acute myeloid leukaemia; BLCA,
bladder urothelial carcinoma; BRCA, breast invasive carcinoma; CESC,
cervical squamous cell carcinoma and endocervical adenocarcinoma;
CHOL, cholangiocarcinoma; COAD, colon adenocarcinoma; DLBC,
diffuse large B-cell lymphoma; ESCA, oesophageal carcinoma; GBM,
glioblastoma multiforme; HNSC, head and neck squamous cell
carcinoma; LGG, low-grade glioma; KICH, kidney chromophobe;
KIRC, renal clear cell carcinoma; KIRP, kidney renal papillary cell
carcinoma; LAML, acute myeloid leukaemia; LIHC, hepatocellular
carcinoma; LUAD, lung adenocarcinoma; LUSC, lung squamous cell
carcinoma; MESO, mesothelioma; NB, neuroblastoma; OV, serous
ovarian cystadenocarcinoma; PAAD, pancreatic adenocarcinoma; PCPG,
pheochromocytoma and paraganglioma; PRAD, prostate adenocarcinoma;
READ, rectum adenocarcinoma; RT, rhabdoid tumour; SARC, sarcoma;
SKCM, skin cutaneous melanoma; STAD, stomach adenocarcinoma;
TGCT, testicular germ cell tumour; THCA, thyroid carcinoma; THYM,
thymoma; UCEC, uterine corpus endometrial carcinoma; UCS, uterine
carcinosarcoma; UVM, uveal melanoma; WT, Wilms tumour. c, Box plots
showing the correlation of BORIS expression with risk status, tumour
stage (primary versus metastasis/recurrence), presence of cancer stem
cells (CD133 positivity) and response to targeted (lapatinib) or cytotoxic
(cisplatin) therapy in the tumour types depicted. NSCLC, non-small cell
lung cancer. Datasets (Mixed Ewing Sarcoma-Savola-117 and NSCLC-
Plamadeala-410) were extracted from the R2: Genomics Analysis and
Visualization Platform (http://r2.amc.nl). GSE7181 (glioblastoma);
GSE16179 (breast cancer); GSE15372 (ovarian cancer). P values
determined by two-sided Wilcoxon rank-sum test. For all panels, sample
sizes (n) are depicted in parenthesis and box plots are as defined in Fig. 4.
