Abstract
Mutations in a diverse set of driver genes increase the fitness of haematopoietic stem cells (HSCs), leading to clonal haematopoiesis1. These lesions are precursors for blood cancers2-6, but the basis of their fitness advantage remains largely unknown, partly owing to a paucity of large cohorts in which the clonal expansion rate has been assessed by longitudinal sampling. Here, to circumvent this limitation, we developed a method to infer the expansion rate from data from a single time point. We applied this method to 5,071 people with clonal haematopoiesis. A genome-wide association study revealed that a common inherited polymorphism in the TCL1A promoter was associated with a slower expansion rate in clonal haematopoiesis overall, but the effect varied by driver gene. Those carrying this protective allele exhibited markedly reduced growth rates or prevalence of clones with driver mutations in TET2, ASXL1, SF3B1 and SRSF2, but this effect was not seen in clones with driver mutations in DNMT3A. TCL1A was not expressed in normal or DNMT3A-mutated HSCs, but the introduction of mutations in TET2 or ASXL1 led to the expression of TCL1A protein and the expansion of HSCs in vitro. The protective allele restricted TCL1A expression and expansion of mutant HSCs, as did experimental knockdown of TCL1A expression. Forced expression of TCL1A promoted the expansion of human HSCs in vitro and mouse HSCs in vivo. Our results indicate that the fitness advantage of several commonly mutated driver genes in clonal haematopoiesis may be mediated by TCL1A activation.

Abstract
Abstract
Esophageal cancer (EsC) is the sixth leading cause of cancer-related mortality worldwide. Esophageal squamous cell cancers (ESCC) typically arise in the upper and mid-esophagus, whereas esophageal adenocarcinomas (EAC) arise in the distal esophagus and gastroesophageal junction. Presently, epigenetic mechanisms contributing to initiation, progression, and dissemination of EsC have not been fully elucidated. The present study was undertaken to determine if induced pluripotent stem cells (iPSCs) derived from normal esophageal epithelial cells (Eso-iPSCs), EsC cell lines cultured in stemness enriched conditions, and cancer stem-like cells isolated from primary EsC specimens could be used to identify unique primitive stem-like transcription factor networks associated with epigenetic plasticity, chemoresistance, and metastatic potential of EsC cells. RNA-seq analysis demonstrated that genes differentially expressed in Eso-iPSC overlapped with transcriptome signatures in lung-iPSC (Lu-iPSC) which we previously generated to identify novel therapeutic targets in lung cancers; similar to Lu-iPSC, Eso-iPSC transcriptome signatures overlapped considerably more with small cell lung cancers (SCLC) compared to non-small cell lung cancers (NSCLC), possibly reflecting greater stemness in SCLC. We next compared transcriptome signatures of Eso-iPSC with stem-like-EAC enrichment models (cell lines and PDX). 6% and 8% of differentially expressed genes in Eso-iPSC uniquely overlapped with EAC or ESCC lines, respectively, whereas 24% were common to Eso-iPSC, EAC cells, and ESCC cells. Culturing of EAC cells on matrigel or propagation of EAC as primary patient derived xenografts increased commonalities of Eso-iPSC and EAC transcriptome signatures. Lastly, we compared transcriptomes of Eso-iPSC with Barrett’s esophagus (BE; a premalignant condition in which the squamous epithelium of the distal esophagus is replaced by metaplastic columnar epithelial cells) and EAC samples. By combining and stringently filtering transcriptome, ATAC-seq, DNA methylome, and ChIP-seq datasets for tissue- and disease-specific signatures, we identified several potentially druggable, master TFs mediating stemness/plasticity, chemoresistance, and metastatic potential which are shared between EsC lines and primary tumor specimens. Enrichment techniques promoted acquisition of more stem-like states in cultured EAC cells as reflected in multi-omic signatures of these cells relative to Eso-iPSC and primary EAC specimens. Collectively, these findings establish proof of principal for our experimental approach which is now being used to further characterize epigenetic mechanisms contributing to esophageal carcinogenesis and to identify novel targets for EsC therapy.
