To study the effects of anti-cancer, anti-metastasis and immune response improvement of aqua-acupuncture with Cistanches Herba infusion solution, we used Cistanches Herba infusion solution(taken by water-alcohol method) put into Chung-wan(CV12) and Chok-Samni(S36) of BALB/c or C57BL/6 which are corresponding to human body. We observed the cytotoxicity, the effect on the expression of MMP-9 gene, the ability to control cancer cell proliferation, change of body weight, surviving number, MST, ILS, changes in amount of WBC, RBC, PLT, total protein, creatinine, glucose and LDH, weight of spleen, number of pulmonary colony, histological analysis on tissue metastasis of lung and liver, splenic cell proliferation, the expression of cytokine gene, the number of $CD4^+$, $CD8^+$, $CD19^+$ and NK cell, and concluded like this. The results were obtained as follows : 1. The cytotoxicity about B16-F10 cell line of $2^0$, $2^{-1}$, $2^{-2}$, $2^{-5}$ diluent groups in Cistanches Herba infusion solution treatment was inhibited significantly, compared with control group. 2. The cytotoxicity about HT1080 cell line of $2^0$, $2^{-1}$, $2^{-2}$, $2^{-3}$, $2^{-5}$, $2^{-8}$ diluent groups in Cistanches Herba infusion solution treatment was inhibited significantly, compared with control group. 3. The effect on expression of MMP-9 gene was decreased in all the sample groups, compared with control group. 4. The effect on the control-ability on the cancer cell proliferation showed cytotooicity significantly in $2^0$, $2^{-1}$, $2^{-2}$, $2^{-3}$, $2^{-4}$, $2^{-5}$ diluent groups. 5. S-180 cancer cell line transplants in BALB/c mice were inhibited significantly in weight increase in all the sample groups, compared with control group. The surviving number increased in almost sample groups, except one group put into Chok-Samni(S36) with 20% Cistanches Herba infusion solution treatment group that showed same number of the control group. 6. S-180 cancer cell line transplants in BALB/c mice showed high MST and ILS significantly in almost sample groups, compared with control group. But one group put into Chok-Samni(S36) with 20% Cistanches Herba infusion solution treatment group showed low MST and ILS than control group. 7. The sample group injected in vein with B16-F10 cancer cell line in C57BL/6 mice showed increased ILS compared with control group significantly in anti-metastasis test. 8. The sample group injected in vein with B16-F10 cancer cell line in C57BL/6 mice were increased significantly in the number of WBC and glucose, and decreased significantly in the amount of LDH, compared with control group. However, there's no significant increase or decrease in number of RBC, PLT, total protein and creatinine. 9. We couldn't find any significant relation in spleen weight of the sample group. 10. In pulmonary colony, sample group was decreased significantly, compared with control group. 11. Histological analysis of sample group inhivited compared with that of control group in both of lung and liver. 12. In immune system, all the sample groups showed having more relevancy to the effect on splenic cell proliferation than normal group. 13. The effect on cytokine gene expression of all the sample groups were increased than control group. 14. In flow cytometry there's no significant relation in number of $CD8^+$, $CD19^+$ cell, however, the number of $CD4^+$ cell and NK cell in sample groups were increased than in control group. Above the results showed that aqua-acupuncture of Cistanches Herba infusion solution has effects of anti-cancer, anti-metastasis and immune response improvement.

Background: Hepatocellular carcinoma (HCC) is a common and aggressive malignancy. Despite of the improvements in its treatment, HCC prognosis remains poor due to its recurrence after resection. This study provides complete genetic profile for Egyptian HCC. Genome-wide analyses were performed to identify the predictive signatures. Patients and Methods: Liver tissue was collected from 31 patients with diagnosis of HCC and gene expression levels in the tumours and their adjacent non-neoplastic tissues samples were studied by analyzing changes by microarray then correlate these with the clinico-pathological parameters. Genes were validated in an independent set by qPCR. The genomic profile was associated with genetic disorders and cancer focused on gene expression, cell cycle and cell death. Molecular profile analysis revealed cell cycle progression and arrest at G2/M, but progression to mitosis; unregulated DNA damage check-points, and apoptosis. Result: Nine hundred fifty eight transcripts out of the 25,000 studied cDNAs were differentially expressed; 503 were up-regulated and 455 were down-regulated. A total of 19 pathways were up-regulated through 27 genes and 13 pathways were down-regulated through 19 genes. Thirty-seven genes showed significant differences in their expression between HCC cases with high and low Alpha Feto Protein ($AFP{\geq}600$ IU/ml). The validation for the microarray was done by real time PCR assay in which PPP3CA, ATG-5, BACE genes showed down-regulation and ABCG2, RXRA, ELOVL2, CXR3 genes showed up-regulation. cDNA microarrays showed that among the major upregulated genes in HCC are sets. Conclusion: The identified genes could provide a panel of new diagnostic and prognostic aids for HCC.

The oncolytic viruses selectively infect and destroy cancer cells, not harming normal cells. The cancer cell materials released by oncolysis, like tumor antigens, stimulate host antitumor immune responses, which is a long-lasting antitumor immunity removing cancer cells in remote parts of the body by a systemic response. Oncolytic viruses armed with transgenes such as cytokines or other immune stimulating factors enhance the immune responses. The first oncolytic virus approved by US-FDA is $Imlygic^{(R)}$ targeting for melanoma. The oncolytic virus is considered as a revolutionary immunotherapy for tumors together with immune checkpoint inhibitors. A variety of oncolytic viruses are under research in the treatment of kidney cancer, liver cancer, breast cancer, and many others solid tumors. Clinical trials have shown promising results in different types of cancers. Here, we present a brief introduction of various aspects of oncolytic virus, and a review of the current status of oncolytic virus therapy development.

Inhibitor of nuclear factor kappa-B kinase beta ($IKK{\beta}$) plays a critical role in cell proliferation and inflammation in various cells by activating $NF-{\kappa}B$ signaling. However, the interrelationship between peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) and $IKK{\beta}$ in cell proliferation is not clear. In this study, we investigated the possible role of $PPAR{\alpha}$ in the hepatic cell death in the absence of $IKK{\beta}$ gene using liver-specific Ikkb-null ($Ikkb^{F/F-AlbCre}$) mice. To examine the function of $PPAR{\alpha}$ activation in hepatic cell death, wild-type ($Ikkb^{F/F}$) and $Ikkb^{F/F-AlbCre}$ mice were treated with $PPAR{\alpha}$ agonist Wy-14,643 (0.1% w/w chow diet) for two weeks. As a result of Wy-14,643 treatment, apoptotic markers including caspase-3 cleavage, poly (ADP-ribose) polymerase (PARP) cleavage and TUNEL-positive staining were significantly decreased in the $Ikkb^{F/F-AlbCre}$ mice. Surprisingly, Wy-14,643 increased the phosphorylation of p65 and STAT3 in both Ikkb and $Ikkb^{F/F-AlbCre}$ mice. Furthermore, BrdU-positive cells were significantly increased in both groups after treatment with Wy-14,643. Our results suggested that $IKK{\beta}-derived$ hepatic apoptosis could be altered by $PPAR{\alpha}$ activation in conjunction with activation of $NF-{\kappa}B$ and STAT3 signaling.

Background: Previously, stingless bee (Trigona spp.) products from East Kalimantan, Indonesia, were successfully screened for in vitro antiproliferative activity against human cancer derived cell lines. It was established that propolis from T. incisa presented the highest in vitro cytotoxicity against the SW620 colon cancer cell line (6% cell survival in $20{\mu}g/mL$). Materials and Methods: Propolis from T. incisa was extracted with methanol and further partitioned with n-hexane, ethyl acetate and methanol. The in vitro cytotoxicity of the extracts was assessed by the MTT assay against human colon (SW620), liver (Hep-G2), gastric (KATO-III), lung (Chago) and breast (BT474) cancer derived cell lines. The active fractions were further enriched by silica gel quick column, absorption and size exclusion chromatography. The purity of each fraction was checked by thin layer chromatography. Cytotoxicity in BT-474 cells induced by cardanol compared to doxorubicin were evaluated by MTT assay, induction of cell cycle arrest and cell death by flow cytometric analysis of propidium iodide and annexin-V stained cells. Results: A cardol isomer was found to be the major compound in one active fraction (F45) of T. incisa propolis, with a cytotoxicity against the SW620 ($IC_{50}$ of $4.51{\pm}0.76{\mu}g/mL$), KATO-III (IC50 of $6.06{\pm}0.39{\mu}g/mL$), Hep-G2 ($IC_{50}$ of $0.71{\pm}0.22{\mu}g/mL$), Chago I ($IC_{50}$ of $0.81{\pm}0.18{\mu}g/mL$) and BT474 (IC50 of $4.28{\pm}0.14{\mu}g/mL$) cell lines. Early apoptosis (programmed cell death) of SW620 cells was induced by the cardol containing F45 fraction at the $IC_{50}$ and $IC_{80}$ concentrations, respectively, within 2-6 h of incubation. In addition, the F45 fraction induced cell cycle arrest at the G1 subphase. Conclusions: Indonesian stingless bee (T. incisa) propolis had moderately potent in vitro anticancer activity on human cancer derived cell lines. Cardol or 5-pentadecyl resorcinol was identified as a major active compound and induced apoptosis in SW620 cells in an early period (${\leq}6h$) and cell cycle arrest at the G1 subphase. Thus, cardol is a potential candidate for cancer chemotherapy.

Iso-suillin, a natural product isolated from Suillus luteus, has been shown to inhibit the growth of some cancer cell lines. However, the molecular mechanisms of action of this compound are poorly understood. The purpose of this study was to investigate how iso-suillin inhibits proliferation and induces apoptosis in a human hepatoma cell line (SMMC-7721). We demonstrated the effects of iso-suillin on cell proliferation and apoptosis in SMMC-7721 cells, with no apparent toxicity in normal human lymphocytes, using colony formation assays and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) analysis. Western blotting was used to examine the expression of $G_1$ phase-regulated and apoptosis-associated protein levels in iso-suillin treated SMMC-7721 cells. The results indicated that iso-suillin significantly decreased viability, induced $G_1$ phase arrest and triggered apoptosis in SMMC-7721cells. Taken together, these results suggest the potential of iso-suillin as a candidate for liver cancer treatment.

Purpose: This analysis was conducted to evaluate the efficacy and safety of icotinib based regimens in treating patients with non-small cell lung cancer (NSCLC). Methods: Clinical studies evaluating the efficacy and safety of icotinib-based regimens with regard to response and safety for patients with NSCLC were identified using a predefined search strategy. Pooled response rates of treatment were calculated. Results: With icotinib-based regimens, 7 clinical studies which including 5,985 Chinese patients with NSCLC were considered eligible for inclusion. The pooled analysis suggested that, in all patients, the positive reponse rate was 30.1% (1,803/5,985) with icotinib-based regimens. Mild skin itching, rashes and diarrhea were the main side effects. No grade III or IV renal or liver toxicity was observed. No treatment-related death occurred in patients treated with icotinib-based regimens. Conclusions: This evidence based analysis suggests that icotinib based regimens are associated with mild response rate and acceptable toxicity for treating Chinese patients with NSCLC.

The current study was conducted to confirm the anti-cancer effect of Sarijang, which is a mixture of extracts from purple bamboo salt, Rhynchosia nulubilis, garlic, and Ulmi cortex. Nude mice were injected with a human-derived colorectal cancer cell (HCT116 cell line) and subsequently administered Sarijang for 4 weeks, following which the body weight, organ weight, and tumor size were measured. To evaluate the anti-cancer mechanism of Sarijang, the levels of p16 and extracellular signal-regulated kinase (ERK), cell cycle regulators in colorectal cancer, were measured. To evaluate the toxicity of Sarijang on liver and kidney, aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine were analyzed. Sarijang not only reduced the tumor size by enhancing p16 and suppressing ERK, but also showed no side-effect in the liver and kidneys. Taken together, Sarijang has the potential to inhibit tumor growth without side effects, and may be used as a useful functional food.

Various mechanisms have been suggested to explain the chemopreventive and tumor-inhibitory effects of melatonin. Despite the growing evidence supporting melatonin-induced mitochondrial dysfunction, it remains largely unknown how this phenomenon modulates metabolic reprogramming in cancer cells. The aim of our study was to identify the mechanism underlying the anti-proliferative and apoptotic effects of melatonin, which is known to inhibit glycolysis. We analyzed the time-dependent effects of melatonin on mitochondrial respiration and glycolysis in liver cancer cells. The results showed that from a cell bioenergetic point of view, melatonin caused an acute reduction in mitochondrial respiration, however, increased reactive oxygen species production, thereby inhibiting mTORC1 activity from an early stage post-treatment without affecting glycolysis. Nevertheless, administration of melatonin for a longer time reduced expression of c-Myc protein, thereby suppressing glycolysis via downregulation of HK2 and LDHA. The data presented herein suggest that melatonin suppresses mitochondrial respiration and glycolysis simultaneously in HCC cells, leading to anti-cancer effects. Thus, melatonin can be used as an adjuvant agent for therapy of liver cancer.
