    Abstract Serine Threonine Kinase 11 (STK11) loss of function (LoF) correlates with anti-PD-1 therapy resistance in patients with KRAS-driven lung adenocarcinoma (LUAD). The molecular mechanisms governing this observation remain unclear and represent a critical outstanding question in the field of lung oncology. As an initial approach to understand this phenomenon, we knocked-out (KO) STK11 in multiple KRAS-driven, STK11-competent human LUAD cell lines and performed whole transcriptome analyses to identify STK11-loss-dependent differential gene expression. Subsequent pathway enrichment studies highlighted activation of the HIPPO/YAP1 signaling axis, along with the induction of numerous tumor-intrinsic cytokines. To validate that YAP1-mediated transcriptional activation occurs in response to STK11 loss, we pursued YAP1 perturbation as a strategy to restore an STK11-competent gene expression profile in STK11-KO LUAD cell lines. Together, our data link STK11 loss with YAP1-mediated transcriptional activation, including the upregulation of immune-evasion promoting cytokines IL-6, CXCL8 and CXCL2. Further, our results raise the intriguing possibility that YAP1 antagonism may represent a therapeutic approach to counter anti-PD-1 therapy resistance in STK11-null, KRAS-driven LUADs by modulating tumor-intrinsic gene expression to promote a "hot" tumor immune microenvironment.

    Abstract Background: Treatment option decisions for low-risk squamous cell carcinoma in situ (SCCIS) are hampered by a paucity of management-type-specific outcomes data.
    Objective: Describe SCCIS tumor outcomes managed by watchful waiting and risk factors associated with poor cancer outcomes.
    Materials and methods: Retrospective cohort study. Setting: Single academic hospital in a rural setting. Patients: Adults with SCCIS diagnosed between January 01, 2014, and December 31, 2016. Main Outcomes and Measures: Hazard ratios (HRs) for local recurrence (LR), nodal metastases (NM), distant metastases (DM), and disease-specific death (DSD).
    Results: A total of 411 consecutive SCCIS tumors that were considered clinically resolved at follow-up and managed with watchful waiting were included. Seventeen tumors recurred locally. No instances of NM, DM, or DSD were identified. Multivariate analysis found that solid-organ transplant recipient status conferred the highest risk of local recurrence [HR, 9.979 (95% CI, 2.249-39.69)]. Additional risk factors predicting LR include anatomic location on the vermilion lip or ear [HR, 9.744 (95% CI, 1.420-69.28)], anatomic location on the head and neck [HR, 6.687 (95% CI, 1.583-36.15)], and a biopsy with tumor extending to the deep edge [HR, 6.562 (95% CI, 1.367-39.04)].
    Conclusion: Watchful waiting for SCCIS with a clinically resolved biopsy site has a local recurrence rate of 4%.

    Abstract Human Histone Locus Bodies (HLBs) are nuclear subdomains comprised of clustered histone genes that are coordinately regulated throughout the cell cycle. We addressed temporal-spatial higher-order genome organization for time-dependent chromatin remodeling at HLBs that supports control of cell proliferation. Proximity distances of specific genomic contacts within histone gene clusters exhibit subtle changes during the G1 phase in MCF10 breast cancer progression model cell lines. This approach directly demonstrates that the two principal histone gene regulatory proteins, HINFP (H4 gene regulator) and NPAT, localize at chromatin loop anchor-points, denoted by CTCF binding, supporting the stringent requirement for histone biosynthesis to package newly replicated DNA as chromatin. We identified a novel enhancer region located ∼ 2 MB distal to histone gene sub-clusters on chromosome 6 that consistently makes genomic contacts with HLB chromatin and is bound by NPAT. During G1 progression the first DNA loops form between one of three histone gene sub-clusters bound by HINFP and the distal enhancer region. Our findings are consistent with a model that the HINFP/NPAT complex controls the formation and dynamic remodeling of higher-order genomic organization of histone gene clusters at HLBs in early to late G1 phase to support transcription of histone mRNAs in S phase.

    Abstract Aging is associated with a gradual loss of lung function due to increased cellular senescence, decreased regenerative capacity, and impaired innate host defense. One important aspect of innate airway epithelial host defense to nonmicrobial triggers is the secretion of alarmins such as IL-33 and activation of type 2 inflammation, which were previously found to depend on activation of the NADPH oxidase (NOX) homolog DUOX1, and redox-dependent signaling pathways that promote alarmin secretion. Here, we demonstrate that normal aging of C57BL/6J mice resulted in markedly decreased lung innate epithelial type 2 responses to exogenous triggers such as the airborne allergen

    Abstract Serine/Threonine Kinase 11 (STK11) encodes an important tumor suppressor that is frequently mutated in lung adenocarcinoma. Clinical studies have shown that mutations in STK11 resulting in loss of function correlate with resistance to anti-PD-1 monoclonal antibody therapy in KRAS-driven non-small cell lung cancer (NSCLC), but the molecular mechanisms responsible remain unclear. Despite this uncertainty, STK11 functional status is emerging as a reliable biomarker for predicting non-response to anti-PD-1 therapy in NSCLC patients. The clinical utility of this biomarker ultimately depends upon accurate classification of STK11 variants. For nonsense variants occurring early in the STK11 coding region, this assessment is straightforward. However, rigorously demonstrating the functional impact of missense variants remains an unmet challenge. Here we present data characterizing four STK11 splice-site variants by analyzing tumor mRNA, and 28 STK11 missense variants using an in vitro kinase assay combined with a cell-based p53-dependent luciferase reporter assay. The variants we report were identified in primary human NSCLC biopsies in collaboration with the University of Vermont Genomic Medicine group. Additionally, we compare our experimental results with data from 22 in silico predictive algorithms. Our work highlights the power, utility and necessity of functional variant assessment and will aid STK11 variant curation, provide a platform to assess novel STK11 variants and help guide anti-PD-1 therapy utilization in KRAS-driven NSCLCs.
