Abstract
The popularity of light/energy devices for cosmetic purposes (e.g., skin care) is increasing. However, the effects and underlying mechanisms remain poorly understood. Commencing in the 1960s, various studies have evaluated the beneficial effects of a light source on cells and tissues. The techniques evaluated include low-level light (laser) therapy and photobiomodulation (PBM). Most studies on PBM used red light sources, but, recently, many studies have employed near-infrared light sources including those of wavelength 800 nm. Here, we used a light-emitting diode (LED) array with a wavelength of 863 nm to treat DMBA/TPA-induced mouse skin tumors; treatment with the array delayed tumor development and reduced the levels of systemic inflammatory cytokines. These results suggest that light therapy could be beneficial. However, the effects were small. Further studies on different skin tumors using an optimized LED setup are required. Combination therapies (conventional methods and an LED array) may be useful.

Abstract
Folates have a pterine core structure and high metabolic activity due to their ability to accept electrons and react with O-, S-, N-, C-bounds. Folates play a role as cofactors in essential one-carbon pathways donating methyl-groups to choline phospholipids, creatine, epinephrine, DNA. Compounds similar to folates are ubiquitous and have been found in different animals, plants, and microorganisms. Folates enter the body from the diet and are also synthesized by intestinal bacteria with consequent adsorption from the colon. Three types of folate and antifolate cellular transporters have been found, differing in tissue localization, substrate affinity, type of transferring, and optimal pH for function. Laboratory criteria of folate deficiency are accepted by WHO. Severe folate deficiencies, manifesting in early life, are seen in hereditary folate malabsorption and cerebral folate deficiency. Acquired folate deficiency is quite common and is associated with poor diet and malabsorption, alcohol consumption, obesity, and kidney failure. Given the observational data that folates have a protective effect against neural tube defects, ischemic events, and cancer, food folic acid fortification was introduced in many countries. However, high physiological folate concentrations and folate overload may increase the risk of impaired brain development in embryogenesis and possess a growth advantage for precancerous altered cells.

Abstract
Abstract. The present study revealed the effects of Lycopene enriched tomato extract (LycT) on chemically induced skin cancer in mice. Skin tumors were induced by topical application of 7,12-Dimethylbenz(a)anthracene (DMBA) [500 nmol/100 ul of acetone, twice a week for two weeks] and 12-O-tetradecanoyl phorbol-13-acetate (TPA) [1.7 nmol/100 ul of acetone, twice a week for eighteen weeks] and LycT (5 mg/kg b.w.) was administered orally. Male Balb/c mice were divided into four groups (n = 15 per group): control, DMBA/TPA, LycT and LycT + DMBA/TPA. The chemopreventive response of LycT to skin tumorigenesis was evident by inhibition in tumor incidence, number, size, burden and volume in LycT + DMBA/TPA group when compared to DMBA/TPA group. This was associated with inhibition of cell proliferation in LycT + DMBA/TPA group as observed by the decrease in epidermal morphometric parameters and mRNA and protein expression of proliferating cell nuclear antigen when compared to DMBA/TPA group (p ≤ 0.05). LycT decreased (p ≤ 0.05) the mRNA and protein expression of angiogenic genes (vascular endothelial growth factor, angiopoietin-2, basic fibroblast growth factor) in LycT + DMBA/TPA group, suggesting its anti-angiogenic effects. The increase (p ≤ 0.05) in protein expression of connexin-32 and 43 in LycT + DMBA/TPA group suggests improved inter cellular communication when compared to DMBA/TPA group. Histochemical studies demonstrated that the components of extracellular matrix (fibrous proteins and mucopolysaccharides) were also modulated during skin carcinogenesis and its chemoprevention by LycT. The decrease in cell proliferation parameters and expression of angiogenesis associated genes, modulation of ECM components and increase in expression of connexins suggest that LycT improved multiple dysregulated processes during chemoprevention of skin cancer.

Abstract
β-Elemene (1-methyl-1-vinyl-2,4-diisopropenyl-cyclohexane), a natural sesquiterpene-derived curcumae radix, exhibits a variety of pharmacologic properties including anticancer. However, the molecular action of β-elemene in chemical-induced skin carcinogenesis remains unclear. Therefore, the present study executes to investigate a possible effect of β-elemene in the 7,12-dimethylbenz(a)anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA)-promoted skin tumor model. The experimental mice were subjected to execute two-stage skin carcinogenesis and it has been initiated by the addition of DMBA on the dorsal portion of the mouse skin. One week after, for chemical carcinogen of mice, topical exposure of DMBA has been induced following with TPA (5 nmol) in acetone (200 μL) given weekly twice for 20 weeks respectively. After completion of the experimental period, we noticed that 100% of tumor incidence, histopathological changes, decreased lipid peroxidation (LPO), and decreased antioxidant levels in DMBA/TPA-promoted skin carcinogenesis. Furthermore, enhanced activity of inflammatory protein markers (nuclear factor [NF]-κB, tumor necrosis factor-α, interleukin-6, cyclooxygenase-2, and nitric oxide synthase) and cell-proliferative messenger RNA markers (PCNA, cyclin D1), and increased antiapoptotic protein Bcl-2; decreased proapoptotic protein marker events Bax and caspase 3 and 9 expressions were noticed in DMBA/TPA promoted skin tissue. In this study, we noticed that β-elemene noticeably reversed the histopathological changes and antioxidant levels in tumor-bearing mice. Conversely, β-elemene effectively inhibits inflammation, cell proliferation events, and enhances proapoptotic factors, by suppression of NF-κB transcriptional activation in DMBA/TPA animals. Thus, we concluded that β-elemene prevents DMBA/TPA promoted skin carcinogenesis through its antioxidant and abate inflammation markers and cell-proliferative markers also activating proapoptotic molecules.

Int Immunopharmacol 2020; 80:106123.

Abstract
Accumulating evidence has shown that SHC SH2 domain-binding protein 1 (SHCBP1) functions as an oncogene and participated in the progression of various cancers. Oroxylin A, an active ingredient extracted from Chinese Medicine Scutellaria baicalensis, shows strong anticancer effects on multiple cancers, however, the pharmacological effect of oroxylin A on skin cancer and the regulatory effect of SHCBP1 on this process have never been evaluated. The present study was aimed at elucidating the effect of oroxylin A on carcinogen (DMBA/TPA)-induced skin tumorigenesis, and to further clarify the role of SHCBP1 in oroxylin A induced antitumor effect. Pretreatment with oroxylin A remarkably inhibited DMBA/TPA-induced tumor formation and growth, and significantly reduced tumor incidence and the average number of tumors per mouse. Oroxylin A suppressed DMBA/TPA-induced skin hyperplasia and tumor proliferation. Oroxylin A significantly inhibited the expression of several inflammatory factors in vivo. In vitro experiments found that oroxylin A inhibited TPA-induced cell malignant transformation of skin epidermal JB6 P + cells. Besides, oroxylin A significantly suppressed the levels of TPA-induced inflammatory factors in vitro. Mechanistic studies showed that oroxylin A remarkably inhibited TPA-induced increased expression of SHCBP1. Overexpression of SHCBP1 attenuated the oroxylin A-induced anti-inflammatory effect. In addition, TPA increased the expression of nuclear NF-κB p65, and SHCBP1 siRNA notably decreased the nuclear NF-κB p65 expression in JB6 P + cells. Collectively, the anti-skin cancer effect of oroxylin A may possibly by inhibiting inflammation via suppression of SHCBP1. Oroxylin A might be a potential candidate compound for the treatment of skin cancer.

Abstract
Background Although folate deficiency has long been implicated in cancer development, uncertainties remain concerning its role in cervical cancer prevention. In particular, the interaction between human papillomavirus (HPV) and folate in the risk of cervical intraepithelial neoplasia (CIN) has been little studied. Objective The goal of this study was to evaluate the dose-response association of serum folate with the risk of CIN, and the potential for HPV to modify the risk of CIN. Design We performed a cross-sectional analysis of screening data in 2304 women aged 19-65 y who participated in an ongoing cohort of 40,000 women in China. Both categoric and spline analyses were used to evaluate the dose-response relation between serum folate and CIN risk. Results After adjusting for potential confounders, a statistically significant inverse association between serum folate concentration and at least grade 2 CIN (CIN2+) risk was observed (1st quartile compared with 4th quartile: OR = 1.40; 95% CI: 1.09, 1.79; P-trend < 0.01); however, serum folate concentration was not associated with CIN1 risk. The risk patterns are similar when limited to only CIN2 and CIN3. An inverse linear relation between increased serum folate concentration and the risk of higher-grade CIN (CIN2, CIN3, and CIN2+) was also observed (for CIN2+: P-overall < 0.01, P-nonlinearity = 0.96). The highest risk of CIN2+ was observed in women with high-risk HPV types, who also had the lowest serum folate concentrations (P-interaction < 0.01). Conclusions Our study indicates that serum folate is inversely associated with the risk of higher-grade CIN in Chinese women either with or without high-risk HPV infection. Thus, maintenance of normal serum folate levels may prove important for reducing the risk of CIN in women.
