Abstract
Although cancer-associated fibroblast (CAF) heterogeneity is well-established, the impact of chemotherapy on CAF populations remains poorly understood. Here we address this question in high-grade serous ovarian cancer (HGSOC), in which we previously identified 4 CAF populations. While the global content in stroma increases in HGSOC after chemotherapy, the proportion of FAP+ CAF (also called CAF-S1) decreases. Still, maintenance of high residual CAF-S1 content after chemotherapy is associated with reduced CD8+ T lymphocyte density and poor patient prognosis, emphasizing the importance of CAF-S1 reduction upon treatment. Single cell analysis, spatial transcriptomics and immunohistochemistry reveal that the content in the ECM-producing ANTXR1+ CAF-S1 cluster (ECM-myCAF) is the most affected by chemotherapy. Moreover, functional assays demonstrate that ECM-myCAF isolated from HGSOC reduce CD8+ T-cell cytotoxicity through a Yes Associated Protein 1 (YAP1)-dependent mechanism. Thus, efficient inhibition after treatment of YAP1-signaling pathway in the ECM-myCAF cluster could enhance CD8+ T-cell cytotoxicity. Altogether, these data pave the way for therapy targeting YAP1 in ECM-myCAF in HGSOC.

Abstract
Cancer is among the world's leading causes of death. A critical challenge for public health is to develop a noninvasive, inexpensive, and efficient tool for early cancer detection. Cancer cells are characterized by an altered metabolism, producing unique patterns of volatile organic compounds (VOCs) that can be used as cancer biomarkers. Dogs can detect VOCs via olfactory associative learning, but training dogs is costly and time-consuming. Insects, such as ants, have a refined sense of smell and can be rapidly trained. We show that individual ants need only a few training trials to learn, memorize, and reliably detect the odor of human cancer cells. These performances rely on specific VOC patterns, as shown by gas chromatography/mass spectrometry. Our findings suggest that using ants as living tools to detect biomarkers of human cancer is feasible, fast, and less laborious than using other animals.

Abstract
Background Early luminal breast cancer (BC) represents 70% of newly diagnosed BC cases. Among them, small (under 2 cm) BC without lymph node metastasis (classified as T1N0) have been rarely studied, as their prognosis is generally favorable. Nevertheless, up to 5% of luminal T1N0 BC patients relapse with distant metastases that ultimately prove fatal. The aim of our work was to identify the mechanisms involved in metastatic recurrence in these patients. Methods Our study addresses the role that autonomous and non-autonomous tumor cell features play with regard to distant recurrence in early luminal BC patients. We created a cohort of T1N0 luminal BC patients (tumors between 0.5–2 cm without lymph node metastasis) with metastatic recurrence (“cases”) and corresponding “controls” (without relapse) matched 1:1 on main prognostic factors: age, grade, and proliferation. We deciphered different characteristics of cancer cells and their tumor micro-environment (TME) by deep analyses using immunohistochemistry. We performed in vitro functional assays and highlighted a new mechanism of cooperation between cancer cells and one particular subset of cancer-associated fibroblasts (CAF). Results We found that specific TME features are indicative of relapse in early luminal BC. Indeed, quantitative histological analyses reveal that “cases” are characterized by significant accumulation of a particular CAF subset (CAF-S1) and decrease in CD4+ T lymphocytes, without any other association with immune cells. In multivariate analysis, TME features, in particular CAF-S1 enrichment, remain significantly associated with recurrence, thereby demonstrating their clinical relevance. Finally, by performing functional analyses, we demonstrated that CAF-S1 pro-metastatic activity is mediated by the CDH11/osteoblast cadherin, consistent with bones being a major site of metastases in luminal BC patients. Conclusions This study shows that distant recurrence in T1N0 BC is strongly associated with the presence of CAF-S1 fibroblasts. Moreover, we identify CDH11 as a key player in CAF-S1-mediated pro-metastatic activity. This is independent of tumor cells and represents a new prognostic factor. These results could assist clinicians in identifying luminal BC patients with high risk of relapse. Targeted therapies against CAF-S1 using anti-FAP antibody or CDH11-targeting compounds might help in preventing relapse for such patients with activated stroma.

Abstract
A subset of cancer-associated fibroblasts (FAP+/CAF-S1) mediates immunosuppression in breast cancers, but its heterogeneity and its impact on immunotherapy response remain unknown. Here, we identify 8 CAF-S1 clusters by analyzing more than 19,000 single CAF-S1 fibroblasts from breast cancer. We validate the five most abundant clusters by flow cytometry and in silico analyses in other cancer types, highlighting their relevance. Myofibroblasts from clusters 0 and 3, characterized by extracellular matrix proteins and TGFβ signaling, respectively, are indicative of primary resistance to immunotherapies. Cluster 0/ecm-myCAF upregulates PD-1 and CTLA4 protein levels in regulatory T lymphocytes (Tregs), which, in turn, increases CAF-S1 cluster 3/TGFβ-myCAF cellular content. Thus, our study highlights a positive feedback loop between specific CAF-S1 clusters and Tregs and uncovers their role in immunotherapy resistance. SIGNIFICANCE: Our work provides a significant advance in characterizing and understanding FAP+ CAF in cancer. We reached a high resolution at single-cell level, which enabled us to identify specific clusters associated with immunosuppression and immunotherapy resistance. Identification of cluster-specific signatures paves the way for therapeutic options in combination with immunotherapies.This article is highlighted in the In This Issue feature, p. 1241.

Abstract
Although fibroblast heterogeneity is recognized in primary tumors, both its characterization in and its impact on metastases remain unknown. Here, combining flow cytometry, immunohistochemistry and RNA-sequencing on breast cancer samples, we identify four Cancer-Associated Fibroblast (CAF) subpopulations in metastatic lymph nodes (LN). Two myofibroblastic subsets, CAF-S1 and CAF-S4, accumulate in LN and correlate with cancer cell invasion. By developing functional assays on primary cultures, we demonstrate that these subsets promote metastasis through distinct functions. While CAF-S1 stimulate cancer cell migration and initiate an epithelial-to-mesenchymal transition through CXCL12 and TGFβ pathways, highly contractile CAF-S4 induce cancer cell invasion in 3-dimensions via NOTCH signaling. Patients with high levels of CAFs, particularly CAF-S4, in LN at diagnosis are prone to develop late distant metastases. Our findings suggest that CAF subset accumulation in LN is a prognostic marker, suggesting that CAF subsets could be examined in axillary LN at diagnosis.

Abstract
Oxidative stress is a major contributor to chronic lung diseases. Antioxidants such as N-acetylcysteine (NAC) are broadly viewed as protective molecules that prevent the mutagenic effects of reactive oxygen species. Antioxidants may, however, increase the risk of some forms of cancer and accelerate lung cancer progression in murine models. Here, we investigated chronic NAC treatment in aging mice displaying lung oxidative stress and cell senescence due to inactivation of the transcription factor JunD, which is downregulated in diseased human lungs. NAC treatment decreased lung oxidative damage and cell senescence and protected from lung emphysema but concomitantly induced the development of lung adenocarcinoma in 50% of JunD-deficient mice and 10% of aged control mice. This finding constitutes the first evidence to our knowledge of a carcinogenic effect of antioxidant therapy in the lungs of aged mice with chronic lung oxidative stress and warrants the utmost caution when considering the therapeutic use of antioxidants.

Abstract
Carcinoma-associated fibroblasts (CAF) are key players in the tumor microenvironment. Here, we characterize four CAF subsets in breast cancer with distinct properties and levels of activation. Two myofibroblastic subsets (CAF-S1, CAF-S4) accumulate differentially in triple-negative breast cancers (TNBC). CAF-S1 fibroblasts promote an immunosuppressive environment through a multi-step mechanism. By secreting CXCL12, CAF-S1 attracts CD4+CD25+ T lymphocytes and retains them by OX40L, PD-L2, and JAM2. Moreover, CAF-S1 increases T lymphocyte survival and promotes their differentiation into CD25HighFOXP3High, through B7H3, CD73, and DPP4. Finally, in contrast to CAF-S4, CAF-S1 enhances the regulatory T cell capacity to inhibit T effector proliferation. These data are consistent with FOXP3+ T lymphocyte accumulation in CAF-S1-enriched TNBC and show how a CAF subset contributes to immunosuppression.

Abstract
Anti‐cancer drugs often increase reactive oxygen species (ROS) and cause DNA damage. Here, we highlight a new cross talk between chronic oxidative stress and the histone variant H2AX, a key player in DNA repair. We observe that persistent accumulation of ROS, due to a deficient JunD‐/Nrf2‐antioxidant response, reduces H2AX protein levels. This effect is mediated by an enhanced interaction of H2AX with the E3 ubiquitin ligase RNF168, which is associated with H2AX poly‐ubiquitination and promotes its degradation by the proteasome. ROS‐mediated H2AX decrease plays a crucial role in chemosensitivity. Indeed, cycles of chemotherapy that sustainably increase ROS reduce H2AX protein levels in Triple‐Negative breast cancer (TNBC) patients. H2AX decrease by such treatment is associated with an impaired NRF2‐antioxidant response and is indicative of the therapeutic efficiency and survival of TNBC patients. Thus, our data describe a novel ROS‐mediated regulation of H2AX turnover, which provides new insights into genetic instability and treatment efficacy in TNBC patients.

Abstract
The triple-negative breast cancer (TN BC) subtype is the most aggressive form of invasive BC. Despite intensive efforts to improve BC treatments, patients with TN BC continue to exhibit poor survival, with half developing resistance to chemotherapy. Here we identify autophagy as a key mechanism in the progression and chemoresistance of a subset of TN tumors. We demonstrate that LC3B, a protein involved in autophagosome formation, is a reliable marker of poor prognosis in TN BC, validating this prognostic value at both the mRNA and protein levels in several independent cohorts. We also show that LC3B has no prognostic value for other BC subtypes (Luminal or HER2 BC), thus revealing a specific impact of autophagy on TN tumors. Autophagy is essential for the proliferative and invasive properties in 3D of TN BC cells characterized by high LC3B levels. Interestingly, the activity of the transcriptional co-activator YAP1 (Yes-associated protein 1) is regulated by the autophagy process and we identify YAP1 as a new actor in the autophagy-dependent proliferative and invasive properties of high-LC3B TN BC. Finally, inhibiting autophagy by silencing ATG5 or ATG7 significantly impaired high-LC3B TN tumor growth in vivo. Moreover, using a patient-derived TN tumor transplanted into mice, we show that an autophagy inhibitor, chloroquine, potentiates the effects of chemotherapeutic agents. Overall, our data identify LC3B as a new prognostic marker for TN BC and the inhibition of autophagy as a promising therapeutic strategy for TN BC patients.

Abstract
JunD regulates genes involved in antioxidant defence. We took advantage of the chronic oxidative stress resulting from junD deletion to examine the role of reactive oxygen species (ROS) in tumour development. In a model of mammary carcinogenesis, junD inactivation increased tumour incidence and revealed an associated reactive stroma. junD-inactivation in the stroma was sufficient to shorten tumour-free survival rate and enhance metastatic spread. ROS promoted conversion of fibroblasts into highly migrating myofibroblasts through accumulation of the hypoxia-inducible factor (HIF)-1α transcription factor and the CXCL12 chemokine. Accordingly, treatment with an antioxidant reduced the levels of HIF and CXCL12 and numerous myofibroblast features. CXCL12 accumulated in the stroma of HER2-human breast adenocarcinomas. Moreover, HER2 tumours exhibited a high proportion of myofibroblasts, which was significantly correlated to nodal metastases. Interestingly, this subset of tumours exhibited a significant nuclear exclusion of JunD and revealed an associated oxido-reduction signature, further demonstrating the relevance of our findings in human cancers. Collectively, our data uncover a new mechanism by which oxidative stress increases the migratory properties of stromal fibroblasts, which in turn potentiate tumour dissemination.

Abstract
JunD, a transcription factor of the AP-1 family, protects cells against oxidative stress. Here, we show that junD(-/-) mice exhibit features of premature aging and shortened life span. They also display persistent hypoglycemia due to enhanced insulin secretion. Consequently, the insulin/IGF-1 signaling pathways are constitutively stimulated, leading to inactivation of FoxO1, a positive regulator of longevity. Hyperinsulinemia most likely results from enhanced pancreatic islet vascularization owing to chronic oxidative stress. Indeed, accumulation of free radicals in beta cells enhances VEGF-A transcription, which in turn increases pancreatic angiogenesis and insulin secretion. Accordingly, long-term treatment with an antioxidant rescues the phenotype of junD(-/-) mice. Indeed, dietary antioxidant supplementation was protective against pancreatic angiogenesis, hyperinsulinemia, and subsequent activation of insulin signaling cascades in peripheral tissues. Taken together, these data establish a pivotal role for oxidative stress in systemic regulation of insulin and define a key role for the JunD protein in longevity.

Abstract
Regulation of gene expression underlies cell differentiation and organogenesis. Both transcription factors and chromatin modifiers are crucial for this process. To study the role of the ATP-dependent SWI/SNF chromatin-remodeling complex in cell differentiation, we inactivated the gene encoding the core complex subunit SNF5/INI1 in the developing liver. Hepatic SNF5 deletion caused neonatal death due to severe hypoglycemia; mutant animals fail to store glycogen and have impaired energetic metabolism. The formation of a hepatic epithelium is also affected in SNF5-deficient livers. Transcriptome analyses showed that SNF5 inactivation is accompanied by defective transcriptional activation of 70% of the genes that are normally upregulated during liver development. These include genes involved in glycogen synthesis, gluconeogenesis and cell-cell adhesion. A fraction of hepatic developmentally activated genes were normally expressed, suggesting that cell differentiation was not completely blocked. Moreover, SNF5-deleted cells showed increased proliferation and we identified several misexpressed genes that may contribute to cell cycle deregulation in these cells. Our results emphasize the role of chromatin remodeling in the activation of cell-type-specific genetic programs and driving cell differentiation.

Abstract
In mammalian cells, the SWI-SNF chromatin-remodeling complex is a regulator of cell proliferation, and overexpression of the catalytic subunit Brm interferes with cell cycle progression. Here, we show that treatment with histone deacetylase (HDAC) inhibitors reduces the inhibitory effect of Brm on the growth of mouse fibroblasts. This observation led to the identification of two carboxy-terminal acetylation sites in the Brm protein. Mutation of these sites into non-acetylatable sequences increased both the growth-inhibitory and the transcriptional activities of Brm. We also show that culture in the presence of HDAC inhibitors facilitates the isolation of clones overexpressing Brm. Removal of the HDAC inhibitors from the growth medium of these clones leads to downregulation of cyclin D1. This downregulation is absent in cell transformed by oncogenic ras.

Abstract
The mammalian SWI-SNF complex is a chromatin-remodelling machinery involved in the modulation of gene expression. Its activity relies on two closely related ATPases known as brm/SNF2alpha and BRG-1/SNF2beta. These two proteins can cooperate with nuclear receptors for transcriptional activation. In addition, they are involved in the control of cell proliferation, most probably by facilitating p105(Rb) repression of E2F transcriptional activity. In the present study, we have examined the ability of various brm/SNF2alpha deletion mutants to reverse the transformed phenotype of ras-transformed fibroblasts. Deletions within the p105(Rb) LXCXE binding motif or the conserved bromodomain had only a moderate effect. On the other hand, a 49-amino-acid segment, rich in lysines and arginines and located immediately downstream of the p105(Rb) interaction domain, appeared to be essential in this assay. This region was also required for cooperation of brm/SNF2alpha with the glucocorticoid receptor in transfection experiments, but only in the context of a reporter construct integrated in the cellular genome. The region has homology to the AT hooks present in high-mobility-group protein I/Y DNA binding domains and is required for the tethering of brm/SNF2alpha to chromatin.

Abstract
The brm and BRG-1 proteins are mutually exclusive subunits of the mammalian SWI-SNF complex. Within this complex, they provide the ATPase activity necessary for transcriptional regulation by nucleosome disruption. Both proteins were recently found to interact with the p105Rb tumor suppressor gene product, suggesting a role for the mammalian SWI-SNF complex in the control of cell growth. We show here that the expression of brm, but not BRG-1, is negatively regulated by mitogenic stimulation, and that growth arrest of mouse fibroblasts leads to increased accumulation of the brm protein. The expression of this protein is also down-regulated upon transformation by the ras oncogene. Re-introduction of brm into ras transformed cells leads to partial reversion of the transformed phenotype by a mechanism that depends on the ATPase domain of the protein. Our data suggest that increased levels of brm protein favour the withdrawal of the cell from the cycle whereas decreased expression of the brm gene may facilitate cellular transformation by various oncogenes.

Abstract
In yeast, the SNF/SWI complex is believed to regulate transcription by locally altering the chromatin structure. At the present time, three human homologues of yeast SNF/SWI proteins have been characterized: hbrm and BRG-1, homologues of SNF2/SWI2, and hSNF5, a homologue of SNF5. We show here that, during mitosis, hbrm and BRG-1 are phosphorylated and excluded from the condensed chromosomes. In this phase of the cell cycle, the level of hbrm protein is also strongly reduced, whereas the level of BRG-1 remains constant. The mitotic phosphorylation of hbrm and BRG-1 is found not to disrupt the association of these proteins with hSNF5 but correlates with a decreased affinity for the nuclear structure in early M phase. We suggest that chromosomal exclusion of the human SNF/SWI complex at the G2-M transition could be part of the mechanism leading to transcriptional arrest during mitosis.

Abstract
In yeast, the SNF/SWI complex is involved in transcriptional activation of several inducible promoters, possibly by causing a local modification of the chromatin structure. Recently, two human homologues of the SNF2/SWI2 protein have been isolated, hbrm and BRG-1. In addition, a complex containing one of the SNF2/SWI2 homologues and having an in vitro activity similar to the yeast complex has been partially purified from HeLa cells. Here we describe the characterization of a cDNA encoding a human nuclear protein containing a large domain of homology with SNF5, another member of the yeast SNF/SWI complex. This protein can be co-immunoprecipitated with hbrm and the interaction between the two proteins is dependent on the region conserved between the human and the yeast SNF5. These findings suggest that the cDNA we have cloned encodes one of the members of the human SNF/SWI complex.

Abstract
The Spi-1/PU.1 protein is an Ets-related transcription factor, whose overexpression is a consequence of SFFV integration in Friend erythroleukemic cells. We present evidence that Spi-1/PU.1 can specifically repress the glucocorticoid-induced activation of promoters carrying a glucocorticoid response element (GRE). Conversely, the glucocorticoid receptor (GR) represses Spi-1/PU.1-mediated transcriptional activation in the presence of hormone. Spi-1/PU.1 also antagonized activation by other nuclear receptors, such as the thyroid hormone or the retinoic acid receptors, in several cell lines, including K562 erythroleukemic cells. These observations suggest that accumulation of the Spi-1/PU.1 protein may interfere with the action of hormones in the erythrocyte differentiation pathway.

Abstract
Comparison of the amino acid sequence of the three members of the mouse jun proto-oncogene family, c-jun, jun B and jun D, reveals several homologous segments. The most C-terminal of them including a leucine zipper motif and a cluster of basic amino acids was previously identified as the DNA binding domain. By deletion analysis, we show that three conserved domains in the N-terminal region are crucial for transactivation by Jun homodimers. Only one of these is predicted to form an acidic amphipathic alpha-helix. The addition of Fos and the formation of Jun-Fos heterodimers strongly increases the transactivation level. Jun mutants that are inactive alone gain partial or full activity in the presence of Fos. This increase strongly depends on the presence of the C-terminal domain of Fos. These results show that in Jun-Fos heterodimers both the N-terminal part of Jun and the C-terminal part of Fos contribute to transactivation with a more pronounced role for the latter.

Abstract
In a transient expression assay in mouse fibroblasts in which neither replication nor T-antigen synthesis occurred, the polyomavirus late promoter functioned faithfully and even more efficiently than the simian virus 40 early promoter. Surprisingly, the DNA sequences upstream of the main transcriptional start sites were not required to obtain the high mRNA level observed. It appeared to result from the combined action of a basal promoter element within the A enhancer domain and of a more downstream element, located in the VP3 intron and abutting the late splice donor. We also show that although an enhancer region was required, enhancer function per se was not. Instead, it appeared that only a defined subset of the DNA-protein interactions necessary for enhancer function was involved in late promoter activity.

Abstract
The 5' end and promoter region of the alpha-subunit gene of chicken muscle acetylcholine receptor was mapped and sequenced. It includes a TATA and a CAAT box and a potential Sp1-binding site. When inserted in front of the chloramphenicol acetyltransferase gene, this promoter (including 850 base pairs of upstream sequence) directed high transient chloramphenicol acetyltransferase expression in transfected mouse C2.7 myotubes but not in C2.7 myoblasts or nonmyogenic 3T6 cells.

Abstract
Two distinct nonoverlapping enhancer elements can be defined within the polyoma enhancer region. In mouse fibroblasts, element A provides a 3-fold higher enhancement of the alpha 2-collagen promoter than element B. In mouse embryonal carcinoma cells, element B shows the same efficiency as in fibroblasts, whereas that of element A decreases by a factor of 3.5. Moreover, a single point mutation (PyEC F9.1) increases the efficiency of element B in both cell types, making it superior to element A in embryonal carcinoma cells. The core of element A is located within a 35 bp region tandem duplicated in several wild-type strains, mostly homologous to a crucial repeated sequence of adenovirus E1a enhancer (Hearing and Shenk, 1983). Element B contains the consensus sequence of Weiher et al. (1982). These two homologies are precisely adjacent to the two DNAase l-hypersensitive sites present in viral chromatin.

Abstract
Eucaryotic expression vectors containing two selective markers, the herpes simplex 1 thymidine kinase gene (tk) and the Escherichia coli gpt gene (Eco gpt) coding for a xanthine-guanine phosphoribosyl-transferase ( XGPRT ) were constructed. These plasmids were used to transfect mouse Ltk- cells followed by selection of either tk+ or XGPRT + colonies. The transcription and maturation of the Eco gpt mRNA is dependent on the presence of a eucaryotic promoter sequence at its 5' end and on the presence of a viral intron and a poly(A) addition site at its 3' end ( Mulligan and Berg, 1980). Here, we report that both simian virus 40 (SV40) and polyoma early and late promoters permit the transcription of this gene integrated into the cellular genome. Polyoma DNA fragments lacking the TATA box, or both the TATA and CAAT boxes directing early transcription, efficiently promote Eco gpt expression. Furthermore, a fragment terminating approximately 300 nucleotides upstream of the initiation site of early RNA permits Eco gpt synthesis when the early strand is joined to the Eco gpt-coding strand. The SV40 early promoter is 2- to 3-fold more efficient than the controlling sequence of late transcription. These results strongly suggest that the switch from a predominance of early RNA to that of late RNA occurring after the onset of DNA replication is caused by the increase in the abundance of template and by the concomitant repression of early transcription by the T antigen. The presence of the tk gene in all the plasmids constructed permits the analysis of Eco gpt expression as a non-selected marker in tk+ clones selected for growth in HAT medium.(ABSTRACT TRUNCATED AT 250 WORDS)
