Abstract
PURPOSE OF REVIEW Breast cancer (BC) is the leading cause of death among women aged 44-55 years globally. Pro-inflammatory food can cause tissue-level inflammation, thereby creating a carcinogenic microenvironment and promoting breast cancer. The aim of this review is to provide an overview of the association between inflammation and nutrition and clinical outcomes in breast cancer survivors. RECENT FINDINGS Pro-inflammatory diets are associated with a higher mortality risk after diagnosis and worse prognosis after treatment. On the other hand, anti-inflammatory diets may improve tissue-level inflammation and improve the overall prognosis and quality of life of survivors. There is strong evidence that the Mediterranean diet in particular is associated with reduced recurrence risk of breast cancer and improved quality of life of survivors. This narrative review provides evidence that there is a strong association between inflammation, dietary habits, and adverse clinical outcomes in breast cancer survivors. It further discusses the current evidence for the role of dietary management in improving clinical outcomes in breast cancer survivors.

Abstract
Although the concomitance of nonalcoholic fatty liver disease (NAFLD) and viral hepatitis is soaring, there is not much knowledge about the impact of NAFLD on viral hepatitis. Here, we aimed to investigate how NAFLD influences the pathogenesis of viral hepatitis. Wild-type C3H/HeN mice with NAFLD induced by high-fat diet were infected with murine hepatitis virus 3 (MHV-3) and sacrificed at Days 4, 8, 12, and 16 post infection. Although there was no difference in the survival rate between mice with and without NAFLD, individuals with steatosis suffered more severe and prolonged liver injury demonstrated by transaminases and histology examination. The intrahepatic viral load was higher in NAFLD group during early infection, although it declined ultimately. On the contrary, the serum antiviral antibody titer remained in a lower level in mice with NAFLD throughout the investigation. In NAFLD group, the production of proinflammatory cytokines (tumor necrosis factor α, interleukin 1β, interleukin 6, and interleukin 17A) and the frequencies of antiviral immune cells (NKG2D+ NK cells and CD69+ cytotoxic T lymphocytes [CTLs]) were profoundly increased. Parallelly, the production of anti-inflammatory cytokine (interleukin 10) and inhibitory checkpoint expression (NKG2A on NK cells and programmed cell death-1 on CTLs) were also significantly elevated to maintain homeostasis. However, the upregulation of interleukin 22, a protective cytokine was deficient in NAFLD group post MHV-3 infection. Conclusively, hepatic lipid metabolic abnormalities disturb antiviral immunity and increase the vulnerability to and severity of viral hepatitis.

Abstract
The increasing incidence rate of breast cancer in the last few decades is known to be linked to the upward trend of obesity prevalence worldwide. The consumption of high-fat diet in particular has been correlated with postmenopausal breast cancer risk. The underlying mechanisms, using suitable and reliable experimental mouse model, however, is lacking. The current review aims to discuss the evidence available from mouse models on the effects of dietary fats intake on postmenopausal breast cancer. We will further discuss the biochemical mechanisms involved in the occurrence of postmenopausal breast cancer. In addition, the methodological considerations and their limitations in obesity-related postmenopausal breast cancer, such as choice of mouse models and breast cancer cell lines as well as the study duration will be reviewed. The current review will provide a platform for further development of new xenograft models which may offer the opportunity to investigate the mechanisms of postmenopausal breast cancer in a greater detail.

Abstract
Adipose tissue is the primary source of many pro-inflammatory cytokines in obesity. Macrophage numbers and pro-inflammatory gene expression are positively associated with adipocyte size. Free fatty acid and tumor necrosis factor-α involve in a vicious cycle between adipocytes and macrophages aggravating inflammatory changes. Thereby, M1 macrophages form a characteristic 'crown-like structure (CLS)' around necrotic adipocytes in obese adipose tissue. In obese women, CLSs of breast adipose tissue are responsible for both increase in local aromatase activity and aggressive behavior of breast cancer cells. Interlinked molecular mechanisms between adipocyte-macrophage-breast cancer cells in obesity involve seven consecutive processes: Excessive release of adipocyte- and macrophage-derived inflammatory cytokines, TSC1-TSC2 complex-mTOR crosstalk, insulin resistance, endoplasmic reticulum (ER) stress and excessive oxidative stress generation, uncoupled respiration and hypoxia, SIRT1 controversy, the increased levels of aromatase activity and estrogen production. Considering elevated risks of estrogen receptor (E2R)-positive postmenopausal breast cancer growth in obesity, adipocyte-macrophage crosstalk is important in the aforementioned issues. Increased mTORC1 signaling in obesity ensures the strong activation of oncogenic signaling in E2Rα-positive breast cancer cells. Since insulin and insulin-like growth factors have been identified as tumor promoters, hyperinsulinemia is an independent risk factor for poor prognosis in breast cancer despite peripheral insulin resistance. The unpredictable effects of adipocyte-derived leptin-estrogen-macrophage axis, and sirtuin 1 (SIRT1)-adipose-resident macrophage axis in obese postmenopausal patients with breast cancer are unresolved mechanistic gaps in the molecular links between the tumor growth and adipocytokines.

Abstract
There is compelling epidemiological evidence linking obesity to many tumours; however, the molecular mechanisms fuelling this association are not clearly understood. Emerging evidence links changes in the tumour microenvironment with the obese state, and murine and human studies highlight the relevance of adipose stromal cells (ASCs), including immune cells, both at remote fat depots, such as the omentum, as well as in peritumoural tissue. These obesity-associated changes have been implicated in several hallmarks of cancer, including the chronic inflammatory state and associated cell signalling, epithelial-to-mesenchymal transition (EMT), tumour-related fibrosis, angiogenesis, and genomic instability. Here, we present a summary of developments over the past 5 years, with particular focus on the tumour microenvironment in the obese state.

Abstract
Several studies show that a significantly stronger association is obvious between increased body mass index (BMI) and higher breast cancer incidence. Furthermore, obese women are at higher risk of all-cause and breast cancer specific mortality when compared to non-obese women with breast cancer. In this context, increased levels of estrogens due to excessive aromatization activity of the adipose tissue, overexpression of pro-inflammatory cytokines, insulin resistance, hyperactivation of insulin-like growth factors (IGFs) pathways, adipocyte-derived adipokines, hypercholesterolemia and excessive oxidative stress contribute to the development of breast cancer in obese women. While higher breast cancer risk with hormone replacement therapy is particularly evident among lean women, in postmenopausal women who are not taking exogenous hormones, general obesity is a significant predictor for breast cancer. Moreover, increased plasma cholesterol leads to accelerated tumor formation and exacerbates their aggressiveness. In contrast to postmenopausal women, premenopausal women with high BMI are inversely associated with breast cancer risk. Nevertheless, life-style of women for breast cancer risk is regulated by avoiding the overweight and a high-fat diet. Estrogen-plus-progestin hormone therapy users for more than 5 years have elevated risks of both invasive ductal and lobular breast cancer. Additionally, these cases are more commonly node-positive and have a higher cancer-related mortality. Collectively, in this chapter, the impacts of obesity-related estrogen, cholesterol, saturated fatty acid, leptin and adiponectin concentrations, aromatase activity, leptin and insulin resistance on breast cancer patients are evaluated. Obesity-related prognostic factors of breast cancer also are discussed at molecular basis.

Abstract
The purpose of this study was to investigate the effects of hawthorn (Crataegus pinnatifida Bunge) extract on the lipid profiles and antioxidant properties in ovariectomized (OVX) rats. After ovariectomy, the rats were randomly divided into four groups: the non-OVX control (Sham), the OVX-control (OVX), the OVX + 100 mg/kg b.w. of hawthorn extract (OL), and the OVX + 200 mg/kg b.w. of hawthorn extract (OH). The final body weights of the OVX group were significantly increased, but the increment was significantly decreased in hawthorn groups (p < 0.05). The serum total and low-density lipoprotein (LDL) cholesterol levels were significantly elevated in the OVX group, whereas the hawthorn groups showed a significant decrease in these levels (p < 0.05). The hepatic triglyceride (TG) and malondialdehyde (MDA) levels were significantly reduced in the hawthorn groups compared with the OVX group (p < 0.05). The mRNA expression of nuclear factor erythroid 2–related factor (Nrf2), heme oxygenase-1 (HO-1), and glutathione peroxidase (GPx) were significantly decreased in the OVX group, whereas the hawthorn groups exhibited a significant increase in expression (p < 0.05). The protein expressions of Nrf2, HO-1, and GPx were lower in the OVX group than the Sham group (p < 0.05). The oral administration of hawthorn extract reversed the suppression of protein levels. These results suggest that hawthorn extract could have protective effects in OVX rats by improving lipid profiles, decreasing oxidative stress, and improving the antioxidant defense system.
