    Abstract Oncolytic ability to direct target and lyse tumor cells makes oncolytic virus therapy (OVT) a promising approach to treating cancer. Despite its therapeutic potential to stimulate anti-tumor immune responses, it also has immunosuppressive effects. The efficacy of OVTs as monotherapies can be enhanced by appropriate adjuvant therapy such as anti-CTLA-4. In this paper, we propose a mathematical model to explore the interactions of combined therapy of oncolytic viruses and a checkpoint inhibitor, anti-CTLA-4. The model incorporates both the susceptible and infected tumor populations, natural killer cell population, virus population, tumor-specific immune populations, virus-specific immune populations, tumor suppressive cytokine IFN-g, and the effect of immune checkpoint inhibitor CTLA-4. In particular, we distinguish the tumor-specific immune abilities of CD8

    Abstract Cells respond to various environmental factors such as nutrients, food intake, and drugs or toxins by undergoing dynamic epigenetic changes. An imbalance in dynamic epigenetic changes is one of the major causes of disease, oncogenic activities, and immunosuppressive effects. The aryl hydrocarbon receptor (AHR) is a unique cellular chemical sensor present in most organs, and its dysregulation has been demonstrated in multiple stages of tumor progression in humans and experimental models; however, the effects of the pathogenic mechanisms of AHR on epigenetic regulation remain unclear. Apart from proto-oncogene activation, epigenetic repressions of tumor suppressor genes are involved in tumor initiation, procession, and metastasis. Reverse epigenetic repression of the tumor suppressor genes by epigenetic enzyme activity inhibition and epigenetic enzyme level manipulation is a potential path for tumor therapy. Current evidence and our recent work on deacetylation of histones on tumor-suppressive genes suggest that histone deacetylase (HDAC) is involved in tumor formation and progression, and treating hepatocellular carcinoma with HDAC inhibitors can, at least partially, repress tumor proliferation and transformation by recusing the expression of tumor-suppressive genes such as

    Abstract Hepatocellular carcinoma (HCC) is the sixth most common type of cancer, and is the third leading cause of cancer-related deaths each year. It involves a multi-step progression and is strongly associated with chronic inflammation induced by the intake of environmental toxins and/or viral infections (i.e., hepatitis B and C viruses). Although several genetic dysregulations are considered to be involved in disease progression, the detailed regulatory mechanisms are not well defined. Homeobox genes that encode transcription factors with homeodomains control cell growth, differentiation, and morphogenesis in embryonic development. Recently, more aberrant expressions of Homeobox genes were found in a wide variety of human cancer, including HCC. In this review, we summarize the currently available evidence related to the role of Homeobox genes in the development of HCC. The objective is to determine the roles of this conserved transcription factor family and its potential use as a therapeutic target in future investigations.

    Abstract Nuclear translocation regulated by phosphorylation is a key step in providing activated mitogen-activated protein kinases (MAPKs) access to their nuclear targets; however, the mechanisms linking MAPK-induced nuclear translocation and target gene expression mediating oncologic activity remain obscure. Here, we show that the MAPK extracellular signal-regulated kinase (ERK) 1, but not ERK2, phosphorylated intestine-specific homeobox (ISX), leading to its nuclear translocation and downstream oncogenic signaling. Mechanistically, ERK1 phosphorylated serine 183 of ISX, facilitating its nuclear translocation and downstream target gene expression. In contrast, dominant-negative ERK1 expression in hepatoma cells inhibited the nuclear translocation of ISX and the expression of downstream genes involved in cell proliferation, malignant transformation, and epithelial-mesenchymal transition in vitro and in vivo. An activating mutation in ISX (S183D) exhibited a constitutive nuclear localization and resistance to sorafenib. Additionally, in 576 paired clinical hepatocellular carcinoma (HCC) samples and adjacent normal tissues, ERK1 and ISX were co-expressed in a tumor-specific manner at mRNA and protein levels, while their mRNA levels showed significant correlation with survival duration, tumor size, number, and stage. These results highlight the significance of ERK1/ISX signaling in HCC progression and its potential as a prognostic and therapeutic target in HCC.

    Abstract Club cells are critical in maintaining airway integrity via, in part, secretion of immunomodulatory Club cell 10 kd protein (CC10) and xenobiotic detoxification. Aryl hydrocarbon receptor (AhR) is important in xenobiotic metabolism, but its role in Club cell function is unclear. To this end, an AhR ligand, 6-formylindolo[3,2-b]carbazole (FICZ, 10 nM) was found to induce, in a ligand and AhR-dependent manner, endoplasmic reticulum stress, phospholipid remodeling, free fatty acid and triglyceride synthesis, leading to perilipin 2-dependent lipid droplet (LD) biogenesis in a Club cell-like cell line, NL20. The increase in LDs was due, in part, to the blockade of adipose triglyceride lipase to LDs, while perilipin 5 facilitated LDs-mitochondria connection, leading to the breakdown of LDs via mitochondrial β-oxidation and acetyl-coA generation. In FICZ-treated cells, increased CC10 secretion and its intracellular association with LDs were noted. Administration of low (0.28 ng), medium (1.42 ng), and high (7.10 ng) doses of FICZ in C57BL/6 mice significantly enhanced lipopolysaccharide (LPS, 0.1 μg)-induced airway inflammation, mucin secretion, pro-inflammatory cytokines and CC10 in the bronchoalveolar lavage fluids, as compared to those seen in mice receiving LPS alone, suggesting the importance of AhR signaling in controlling the metabolic homeostasis and functions of Club cells.

    Abstract B-cell precursor acute lymphoblastic leukemia (BCP-ALL), the most common childhood cancer, originates from lymphoid precursor cells in bone marrow committed to the B-cell lineage. Environmental factors and genetic abnormalities disturb the normal maturation of these precursor cells, promoting the formation of leukemia cells and suppressing normal hematopoiesis. The underlying mechanisms of progression are unclear, but BCP-ALL incidence seems to be increasing in parallel with the adoption of modern lifestyles. This study hypothesized that air pollution and haze are risk factors for BCP-ALL progression. The current study revealed that indeno(1,2,3-cd)pyrene (IP), a major component of polycyclic aromatic hydrocarbons (PAHs) in air, promotes oncogenic activities (proliferation, transformation, and disease relapse) in vitro and in vivo. Mechanistically, IP treatment activated the aryl hydrocarbon receptor (AHR)-indoleamine-2,3-dioxygenase (IDOs) axis, thereby enhancing tryptophan metabolism and kynurenine (KYN) level and consequent promoting the KYN-AHR feedback loop. IP treatment decreased the time to disease relapse and increased the BCP-ALL cell count in an orthotopic xenograft mouse model. Additionally, in 50 clinical BCP-ALL samples, AHR and IDO were co-expressed in a disease-specific manner at mRNA and protein levels, while their mRNA levels showed a significant correlation with disease-free survival duration. These results indicated that PAH/IP exposure promotes BCP-ALL disease progression.

    Abstract Background: Club cells play an important role in maintaining lung homeostasis and aryl hydrocarbon receptor (AhR) is known to be important in xenobiotic metabolism, but its role in regulating club cells is currently unknown.
    Methods: To this end, mice with club cell-specific AhR deficiency were generated and evaluated in a model of antigen (ovalbumin, OVA)-induced airway inflammation for the number of infiltrating inflammatory cells, the levels of cytokines and CC10 and Notch signaling by standard methods.
    Results: After OVA sensitization and challenge,
    Conclusion: Under the condition of pulmonary inflammation, AhR is critical in controlling lung club cell homeostasis via targeting Notch1 signaling and the generation of anti-inflammatory mediators.

    Abstract Epigenetic regulation is important for cancer progression; however, the underlying mechanisms, particularly those involving protein acetylation, remain to be fully understood. Here, we show that p300/CBP-associated factor (PCAF)-dependent acetylation of the transcription factor intestine-specific homeobox (ISX) regulates epithelial-mesenchymal transition (EMT) and promotes cancer metastasis. Mechanistically, PCAF acetylation of ISX at lysine 69 promotes the interaction with acetylated bromodomain-containing protein 4 (BRD4) at lysine 332 in tumor cells, and the translocation of the resulting complex into the nucleus. There, it binds to promoters of EMT genes, where acetylation of histone 3 at lysines 9, 14, and 18 initiates chromatin remodeling and subsequent transcriptional activation. Ectopic ISX expression enhances EMT marker expression, including TWIST1, Snail1, and VEGF, induces cancer metastasis, but suppresses E-cadherin expression. In lung cancer, ectopic expression of PCAF-ISX-BRD4 axis components correlates with clinical metastatic features and poor prognosis. These results suggest that the PCAF-ISX-BRD4 axis mediates EMT signaling and regulates tumor initiation and metastasis.
