Abstract
Epidemiological studies have shown that plasma HDL-C levels are closely related to the risk of prostate cancer, breast cancer, and other malignancies. As one of the key carriers of cholesterol regulation, high-density lipoprotein (HDL) plays an important role in tumorigenesis and cancer development through anti-inflammation, antioxidation, immune-modulation, and mediating cholesterol transportation in cancer cells and noncancer cells. In addition, the occurrence and progression of cancer are closely related to the alteration of the tumor microenvironment (TME). Cancer cells synthesize and secrete a variety of cytokines and other factors to promote the reprogramming of surrounding cells and shape the microenvironment suitable for cancer survival. By analyzing the effect of HDL on the infiltrating immune cells in the TME, as well as the relationship between HDL and tumor-associated angiogenesis, it is suggested that a moderate increase in the level of HDL in vivo with consequent improvement of the function of HDL in the TME and induction of intracellular cholesterol efflux may be a promising strategy for cancer therapy.

Abstract
BACKGROUND Tumor cells benefit from tumor-associated macrophages (TAMs) promoting tumor growth and modulating functions of other cells in tumor microenvironment (TME). However, how tumor cells regulate the property of TAMs during tumor invasion remains to be defined. METHODS Mouse tumor models and cancer patients' samples were analyzed to determine LAMP2a expression in TAMs. In vitro mouse primary macrophages were used to assess LAMP2a-modulated macrophage activation, and to verify LAMP2a's target proteins. The effect of LAMP2a-knockdown on tumor progression and TME maintaining was determined by using mouse tumor models. FINDINGS Lysosome associated membrane protein type 2A (LAMP2a) is upregulated in TAMs by tumor cells and important for tumor progression. LAMP2a expression in TAMs, but not in tumor cells, is associated with poor prognosis in breast cancer. LAMP2a inactivation induced by either shRNA or CRISPR/Cas9 prevents TAMs activation and tumor growth. LAMP2a degrades PRDX1 (peroxiredoxin 1) and CRTC1 (CREB-regulated transcription coactivator 1) to promote macrophage pro-tumorigenic activation. INTERPRETATION Our study suggests that tumor cells utilize LAMP2a-PRDX1/CRTC1 axis to modulate TAMs activation and promote tumor growth, reveals the role of LAMP2a in macrophage study and TAM-targeting tumor immunotherapy.

Abstract
Tumor-associated macrophages (TAMs) are known to regulate tumor response to many anti-cancer therapies, including oncolytic virotherapy. Oncolytic virotherapy employing oncolytic paramyxoviruses, such as attenuated measles (MeV) and mumps (MuV) viruses, has demonstrated therapeutic potential against various malignancies. However, the response of TAMs to oncolytic paramyxoviruses and the consequent effect on virotherapeutic efficacy remains to be characterized. Here, we demonstrate that the presence of human monocyte-derived macrophages (MDMs), irrespective of initial polarization state, enhances the virotherapeutic effect of MeV and MuV on breast cancer cells. Notably, our finding contrasts those of several studies involving other oncolytic viruses, which suggest that TAMs negatively impact virotherapeutic efficacy by impeding virus replication and dissemination. We found that the enhanced virotherapeutic effect in the presence of MDMs was due to slightly delayed proliferation and significantly elevated cell death that was not a result of increased virus replication. Instead, we found that the enhanced virotherapeutic effect involved several macrophage-associated anti-tumor mediators, and was associated with the modulation of MDMs towards an anti-tumor phenotype. Our findings present an alternative view on the role of TAMs in oncolytic virotherapy, and highlight the immunotherapeutic potential of oncolytic paramyxoviruses; possibly contributing towards the overall efficacy of oncolytic virotherapy.

Abstract
ATP-binding Cassette Transporter G1 (ABCG1) promotes cholesterol efflux from cells and regulates intracellular cholesterol homeostasis. Here, we demonstrate a role of ABCG1 as a mediator of tumor immunity. Abcg1−/− mice have dramatically suppressed subcutaneous MB49-bladder carcinoma and B16-melanoma growth and prolonged survival. We show that reduced tumor growth in Abcg1−/− mice is myeloid cell-intrinsic and is associated with a phenotypic shift of the macrophages from a tumor-promoting M2 to a tumor-fighting M1 within the tumor. Abcg1−/− macrophages exhibit an intrinsic bias toward M1 polarization with increased NF-κB activation and direct cytotoxicity for tumor cells in vitro. Overall, our study demonstrates that absence of ABCG1 inhibits tumor growth through modulation of macrophage function within the tumor and illustrates a link between cholesterol homeostasis and cancer.
