Abstract
Tissue stem-progenitor cell frequency has been implicated in tumor risk and progression, but tissue-specific factors linking these associations remain ill-defined. We observed that stiff breast tissue from women with high mammographic density, who exhibit increased lifetime risk for breast cancer, associates with abundant stem-progenitor epithelial cells. Using genetically engineered mouse models of elevated integrin mechanosignaling and collagen density, syngeneic manipulations, and spheroid models, we determined that a stiff matrix and high mechanosignaling increase mammary epithelial stem-progenitor cell frequency and enhance tumor initiation in vivo. Augmented tissue mechanics expand stemness by potentiating extracellular signal-related kinase (ERK) activity to foster progesterone receptor-dependent RANK signaling. Consistently, we detected elevated phosphorylated ERK and progesterone receptors and increased levels of RANK signaling in stiff breast tissue from women with high mammographic density. The findings link fibrosis and mechanosignaling to stem-progenitor cell frequency and breast cancer risk and causally implicate epidermal growth factor receptor-ERK-dependent hormone signaling in this phenotype.

Abstract
Resistance to antitumor treatment contributes to patient mortality. Functional proteomic screening of organoids derived from chemotherapy-treated patients with breast cancer identified nuclear receptor corepressor 2 (NCOR2) histone deacetylase as an inhibitor of cytotoxic stress response and antitumor immunity. High NCOR2 in the tumors of patients with breast cancer predicted chemotherapy refractoriness, tumor recurrence and poor prognosis. Molecular studies revealed that NCOR2 inhibits antitumor treatment by regulating histone deacetylase 3 (HDAC3) to repress interferon regulatory factor 1 (IRF-1)-dependent gene expression and interferon (IFN) signaling. Reducing NCOR2 or impeding its epigenetic activity by modifying its interaction with HDAC3 enhanced chemotherapy responsiveness and restored antitumor immunity. An adeno-associated viral NCOR2-HDAC3 competitor potentiated chemotherapy and immune checkpoint therapy in culture and in vivo by permitting transcription of IRF-1-regulated proapoptosis and inflammatory genes to increase IFN-γ signaling. The findings illustrate the utility of patient-derived organoids for drug discovery and suggest that targeting stress and inflammatory-repressor complexes such as NCOR2-HDAC3 could overcome treatment resistance and improve the outcome of patients with cancer.

Abstract
Women with dense breasts have an increased lifetime risk of malignancy that has been attributed to a higher epithelial density. Quantitative proteomics, collagen analysis, and mechanical measurements in normal tissue revealed that stroma in the high-density breast contains more oriented, fibrillar collagen that is stiffer and correlates with higher epithelial cell density. microRNA (miR) profiling of breast tissue identified miR-203 as a matrix stiffness-repressed transcript that is downregulated by collagen density and reduced in the breast epithelium of women with high mammographic density. Culture studies demonstrated that ZNF217 mediates a matrix stiffness- and collagen density-induced increase in Akt activity and mammary epithelial cell proliferation. Manipulation of the epithelium in a mouse model of mammographic density supported a causal relationship between stromal stiffness, reduced miR-203, higher levels of the murine homolog Zfp217, and increased Akt activity and mammary epithelial proliferation. ZNF217 was also increased in the normal breast epithelium of women with high mammographic density, correlated positively with epithelial proliferation and density, and inversely with miR-203. The findings identify ZNF217 as a potential target toward which preexisting therapies, such as the Akt inhibitor triciribine, could be used as a chemopreventive agent to reduce cancer risk in women with high mammographic density.

Abstract
Abstract
A considerable challenge in glioblastoma (GBM) therapy is treatment resistance and tumor recurrence, resulting in dismal patient prognosis. GBM aggression and recurrence is often associated with a mesenchymal phenotype, increased expression of glycoproteins and the presence of glioma-initiating “stem-like” cells. Using patient-derived xenograft models, and immune competent syngeneic and transgenic glioma mouse models, we show that aggressive mesenchymal-like GBMs, reminiscent of recurrent GBM, are mechanically stiffer, present with a bulky glycocalyx and demonstrate a stem-like phenotype. We report that the more aggressive mesenchymal GBMs show increased mechanical signaling and contractility, and their tumors are surrounded by a stiffer ECM that maintains and even further enhances integrin mechanosignaling. Since a large proportion of these bulky glycoproteins are also stem markers, upregulation of the glycoproteins and their modulators leads to enhanced GBM stem-ness. This was evident both in our mesenchymal models of GBM as well as multiple patient datasets which compared paired primary and recurrent GBM RNA sequencing and protein data. In addition to stem-ness, we show that the mechanically “enhanced” GBMs also foster a differential immune landscape, infiltrated by type 2 macrophages, believed to be pro-tumorigenic and immune evasive. Our findings suggest that there is a dynamic and reciprocal link between integrin mechanosignaling, the GBM immune landscape and a bulky glycocalyx, which promotes a mesenchymal, stem-like phenotype and likely recurrence in GBM patients. Thus, therapeutic strategies to target GBM tissue tension could prevent recurrence, reduce mortality and improve patient outcome.

Abstract
Estrogen receptor α (ERα) is expressed in tissues as diverse as brains and mammary glands. In breast cancer, ERα is a key regulator of tumor progression. Therefore, understanding what activates ERα is critical for cancer treatment in particular and cell biology in general. Using biochemical approaches and superresolution microscopy, we show that estrogen drives membrane ERα into endosomes in breast cancer cells and that its fate is determined by the presence of fibronectin (FN) in the extracellular matrix; it is trafficked to lysosomes in the absence of FN and avoids the lysosomal compartment in its presence. In this context, FN prolongs ERα half-life and strengthens its transcriptional activity. We show that ERα is associated with β1-integrin at the membrane, and this integrin follows the same endocytosis and subcellular trafficking pathway triggered by estrogen. Moreover, ERα+ vesicles are present within human breast tissues, and colocalization with β1-integrin is detected primarily in tumors. Our work unravels a key, clinically relevant mechanism of microenvironmental regulation of ERα signaling.

Abstract
The glycocalyx is a coating of protein and sugar on the surface of all living cells. Dramatic perturbations to the composition and structure of the glycocalyx are frequently observed in aggressive cancers. However, tools to experimentally mimic and model the cancer-specific glycocalyx remain limited. Here, we develop a genetically encoded toolkit to engineer the chemical and physical structure of the cellular glycocalyx. By manipulating the glycocalyx structure, we are able to switch the adhesive state of cells from strongly adherent to fully detached. Surprisingly, we find that a thick and dense glycocalyx with high O-glycan content promotes cell survival even in a suspended state, characteristic of circulating tumor cells during metastatic dissemination. Our data suggest that glycocalyx-mediated survival is largely independent of receptor tyrosine kinase and mitogen activated kinase signaling. While anchorage is still required for proliferation, we find that cells with a thick glycocalyx can dynamically attach to a matrix scaffold, undergo cellular division, and quickly disassociate again into a suspended state. Together, our technology provides a needed toolkit for engineering the glycocalyx in glycobiology and cancer research.

Integrin expression and activity are altered in tumors, and aberrant integrin signaling promotes malignancy. However, how integrins become altered in tumors remains poorly understood. We discovered that oncogenic activation of MEK signaling induces cell growth and survival, and promotes the malignant phenotype of mammary epithelial cells (MECs) by increasing α5 integrin expression. We determined that MEK activates c-Myc to reduce the transcription of the SWI/SNF chromatin remodeling enzyme Brahma (BRM). Our studies revealed that reduced BRM expression and/or activity drives the malignant behavior of MECs by epigenetically promoting C/EBPβ expression to directly induce α5 integrin transcription. Consistently, we could show that restoring BRM levels normalized the malignant behavior of transformed MECs in culture and in vivo by preventing C/EBPβ-dependent α5 integrin transcription. Our findings identify a novel mechanism whereby oncogenic signaling promotes malignant transformation by regulating transcription of a key chromatin remodeling molecule that regulates integrin-dependent stromal-epithelial interactions.

Abstract
Clusterin is a ubiquitous, heterodimeric glycoprotein with multiple possible functions that are likely influenced by glycosylation. Identification of oligosaccharide attachment sites and structural characterization of oligosaccharides in human serum clusterin has been performed by mass spectrometry and Edman degradation. Matrix-assisted laser desorption ionization mass spectrometry revealed two molecular weight species of holoclusterin (58,505 +/- 250 and 63,507 +/- 200). Mass spectrometry also revealed molecular heterogeneity associated with both the alpha and beta subunits of clusterin, consistent with the presence of multiple glycoforms. The data indicate that clusterin contains 17-27% carbohydrate by weight, the alpha subunit contains 0-30% carbohydrate and the beta subunit contains 27-30% carbohydrate. Liquid chromatography electrospray mass spectrometry with stepped collision energy scanning was used to selectively identify and preparatively fractionate tryptic glycopeptides. Edman sequence analysis was then used to confirm the identities of the glycopeptides and to define the attachment sites within each peptide. A total of six N-linked glycosylation sites were identified, three in the alpha subunit (alpha 64N, alpha 81N, alpha 123N) and three in the beta subunit (beta 64N, beta 127N, and beta 147N). Seven different possible types of oligosaccharide structures were identified by mass including: a monosialobiantennary structure, bisialobiantennary structures without or with one fucose, trisialotriantennary structures without or with one fucose, and possibly a trisialotriantennary structure with two fucose and/or a tetrasialotriantennary structure. Site beta 64N exhibited the least glycosylation diversity, with two detected types of oligosaccharides, and site beta 147N exhibited the greatest diversity, with five or six detected types of oligosaccharides. Overall, the most abundant glycoforms detected were bisialobiantennary without fucose and the least abundant were monosialobiantennary, trisialotriantennary with two fucose and/or tetrasialotriantennary. Clusterin peptides accounting for 99% of the primary structure were identified from analysis of the isolated alpha and beta subunits, including all Ser- and Thr-containing peptides. No evidence was found for the presence of O-linked or sulfated oligosaccharides. The results provide a molecular basis for developing a better understanding of clusterin structure-function relationships and the role clusterin glycosylation plays in physiological function.

Abstract
Male sexual differentiation is a process that involves androgen action via the androgen receptor. Defects in the androgen receptor, many resulting from point mutations in the androgen receptor gene, lead to varying degrees of impaired masculinization in chromosomally male individuals. To date no specific androgen regulated morphogens involved in this process have been identified and no marker genes are known that would help to predict further virilization in infants with partial androgen insensitivity. In the present study we first show data on androgen regulated gene expression investigated by differential display reverse transcription PCR (dd RT PCR) on total RNA from human neonatal genital skin fibroblasts cultured in the presence or absence of 100 nM testosterone. Using three different primer combinations, 54 cDNAs appeared to be regulated by androgens. Most of these sequences show the characteristics of expressed mRNAs but showed no homology to sequences in the database. However 15 clones with significant homology to previously cloned sequences were identified. Seven cDNAs appear to be induced by androgen withdrawal. Of these, five are similar to ETS (expression tagged sequences) from unknown genes; the other two show significant homology to the cDNAs of ubiquitin and human guanylate binding protein 2 (GBP-2). In addition, we have identified 8 cDNA clones which show homologies to other sequences in the database and appear to be upregulated in the presence of testosterone. Four of these clones again are similar to ETS from unknown genes. Three differential expressed sequences that appear to be upregulated in the presence of testosterone show significant homology to the cDNAs of L-plastin and one to the cDNA of testican. This latter gene codes for a proteoglycan involved in cell social behavior and therefore of special interest in this context. The results of this study are of interest in further investigation of normal and disturbed androgen-dependent gene expression.
