2.Melatonin in the treatment of cancer and its mechanism
Chinese Pharmacological Bulletin 1986;0(04):-
Melatonin, a neuroendocrine hormone secreted by the pineal gland, is involved in numerous physiological processes including circadian rhythms, immune function, antioxidant and anti-inflammatory activities. This overview summarizes the growing evidences of melatonin as a promising agent for cancer treatment and possible cancer prevention. To date, the chemopreventive, oncostatic, and tumor inhibitory effects of melatonin have become a hot area of investigation, particularly in breast cancer, melanoma, colon cancer, lung cancer and prostatic carcinoma. Multiple mechanisms including interacting with the estrogen-signaling pathways and affecting telomerase activation have been suggested for the biological effects of melatonin. Melatonin not only seems to control development alone but is highlighted in increasing the efficacy and decreasing the side effects of chemotherapy when used in adjuvant therapeutics.

Aim To investigate the effects of ghrelin on alcohol-induced liver injury. Methods The alcoholic liver injury mouse model was induced by chronic etha-nol feeding ( 4-week ad libitum oral feeding with the ethanol liquid diet) plus a single binge ethanol (5 g· kg-1 ) feeding. The level of alanine aminotransferase (ALT), aspartate aminotransferase (AST) in serum, malondiadehyde ( MDA ) content, superoxide dis-mutase (SOD) and glutathione peroxidase (GSH-Px) activities in liver homogenate were assayed by spectro-photometer. Hepatic pathological examination was ob-served by HE staining. The mRNA expression of proin-flammatory cytokines including TNF-α, IL-1β, IFN-γ, IL-6 and MCP-1 in the liver was measured by real-time PCR method. Results This chronic-plus-single-binge high dose ethanol feeding synergistically induced liver injury, inflammation and fatty liver change. Treatment with Ghrelin ( 5 , 10 , 20 μg · kg-1 ) significantly de-creased the enhanced level of transaminase ( ALT, AST) in serum, improved the pathologic change in liv-er, and reduced the infiltration of inflammatory cells induced by alcohol administration. Ghrelin also de-creased MDA content and increased the reduced SOD and GSH-Px level in liver homogenate. Furthermore, ghrelin decreased inflammatory cytokines mRNA ex-pression including TNF-α, IL-1β, IFN-γ, IL-6 and MCP-1 in the liver. Conclusion Ghrelin has protec-tive effects against alcoholic liver injury in mice via in-hibiting inflammation and suppressing oxidative stress.

Aim To establish a mouse breast cancer model stab-ly expressing HER2. Methods 4T1-Luc mouse breast cancer cell line was transfected with the full-length human HER2 gene and selected with G418. The HER2 expression in 4T1-Luc stable cells was detected by fluorescence-activated cell sorting ( FACS) and Western blot. 4T1-Luc/HER2 cells were implanted into the mammary fat pads of BALB/c or nude mice. After tumor stabili-zation, mice were randomly assigned into 4 groups for treatment with PBS control, chA21, Trastuzumab, or chA21 plus Trastu-zumab. Tumor volumes were measured and tumor growth inhibi-tion ratios were calculated twice a week. At the end of experi-ment, tumor metastasis in mice was detected by bioluminescence imaging technology. Results Several 4T1-Luc/HER2 stable cell clones were obtained after G418 selection. FACS and West-ern blot analysis showed that all clones expressed HER2 protein at high levels. These 4T1-Luc/HER2 clones showed good tumor-igenicity in mice with steady tumor growth after one week of cell implantation. After 2-3 weeks, metastatic tumor cells were seen in the lung, cheek and groin areas. In BALB/c mice, the tumor growth inhibition ratio was 43. 3% in chA21 plus Trastuzumab group (P<0. 05 vs PBS control), which was higher than chA21 group (11. 1%) or Trastuzumab group (23%). In addition, the luminescence number and density of tumor metastases in lungs were significantly reduced in the antibody combination group. Conclusions The mouse model of spontaneously metastasizing breast cancer with HER2 overexpression is successfully estab-lished. The preliminary study suggests that anti-HER2 antibody combination of chA21 and Trastuzumab has excellent inhibitory effects on tumor growth and metastasis.

Objective To study the changes of circulating triglyceride (TG) in the obese elderly, and to investigate the effect of hypertriglyceridemia on the development of insulin resistance. Methods A total of 82 subjects were divided into simple obesity group, obesity with IGT group, obesity with T2DM group and normal control group. The body height, body weight, blood pressure, fasting plasma glucose (FPG) and insulin(FPI), circulating TG and total cholesterol (TC) were measured. The homeostasis model assessment-insulin resistance (HOMA-IR) was calculated. Results The levels of serum TG were significantly higher in the simple obesity group ( 1.3 ± 0. 6) mmol/L, obesity with IGT group (1.9 ± 0.9)mmol/L and obesity with T2DM group (2.1±0.7) mmol/L than in the normal controls [(1.0±0.2)mmol/L, all P<0. 05], Furthermore, the levels of TG, FPG, FPI, HOMA-IR and systolic pressure were significantly higher(all P<0. 05) in obesity with IGT group and obesity with T2DM group than in simple obesity group. There were significantly positive correlations between TG and body mass index (BMI), FPG, HOMA-IR, TC, systolic pressure respectively (all P < 0.05). Multiple linear regression analysis indicated that FPG and HOMA-IR were the independent factors affecting TG (both P < 0. 05 ). Conclusions Hypertriglyceridemia may play an important role in the development of insulin resistance.
