Joo-Yeon Chung, Yoo-Sun Kim, Yuri Kim, Sang-Ho Yoo
Increased sugar consumption has been proposed to be a risk factor for obesity-related metabolic disorders. The objective of this study was to investigate the anti-inflammatory effect of turanose in Raw 264.7 macrophages. Turanose (3-O-α-D-glucosyl-D-fructose), an isomer of sucrose, naturally exists in honey. For these studies, macrophages were treated with total glucose (Glu), 50% Glu/50% turanose (T50), 25% Glu/75% turanose (T75), and 100% turanose (T100), each with a total concentration of 25 mM in cell media...

Cerulein-induced pancreatitis is similar to human edematous pancreatitis, characterized by the dysregulation of digestive enzyme production, edema formation, and an infiltration of inflammatory cells into the pancreas. We previously showed that the Janus kinase 2 (JAK2)/STAT3 pathway mediates inflammatory signaling in cerulein-stimulated pancreatic acinar cells. PPAR-γ has been implicated in the regulation of inflammatory responses in several cells. In the present study, we investigated the role of PPAR-γ in cerulein-induced activation of JAK2/STAT3 in pancreatic acinar cells...

BACKGROUND: Chemopreventive effects and the underlying mechanisms of blueberry (Vaccinium spp.) are not clearly understood in human. We hypothesized blueberry would work via antioxidative and epigenetic modulation, which is similar to vitamin C. METHODS: We performed a pilot and non-inferiority study in healthy young women (n = 12), who consumed vitamin C (1 g/d) or 240 mL of blueberry juice (total polyphenols 300 mg and proanthocyanidin 76 mg/d) for 2 weeks. We analyzed 8-hydroxydeoxyguanosine (8-OHdG) and malondialdehyde (MDA) levels in their urine, and global and specific DNA methylation at the NAD(P)H quinone oxidoreductase 1 (NQO1), methylenetetrahydrofolate reductase (MTHFR), or DNA methyltransferase 1 (DNMT1) genes in their blood...

BACKGROUND: Anthocyanin-rich foods and preparations have been reported to reduce the risk of life-style related diseases, including cancer. The SL222 sweet potato, a purple-fleshed cultivar developed in New Zealand, accumulates high levels of anthocyanins in its storage root. METHODS: We examined the chemopreventative properties of the SL222 sweet potato in the C57BL/6J-APC (MIN/+) (APC(MIN)) mouse, a genetic model of colorectal cancer. APC(MIN) and C57BL/6J wild-type mice (n=160) were divided into four feeding groups consuming diets containing 10% SL222 sweet potato flesh, 10% SL222 sweet potato skin, or 0...

REVIEW
Hae-Yun Chung, Yoo Kyoung Park
Ketogenic diet has been used for more than 80 years as a successful dietary regimen for epilepsy. Recently, dietary modulation by carbohydrate depletion via ketogenic diet has been suggested as an important therapeutic strategy to selectively kill cancer cells and as adjuvant therapy for cancer treatment. However, some researchers insist ketogenic diet to be highly undesirable as ketogenic diet may trigger and/or exacerbate cachexia development and usually result in significant weight loss. This review revisits the meaning of physiological ketosis in the light of this evidence and considers possibility of the use of ketogenic diet for oncology patients...

There are many of methods of treating cancer. However, the concept of curing the cancer is beyond our current knowledge. Some patients who have the cancer may seek an alternative manner of curing their disease. Alternative medicines, such as spiritual and complementary therapy, are able to cure the cancer and, at the least, are safe. Research on the importance of spirituality in cancer care has mainly been performed in geographically heterogeneous populations. The results are limited to these specific religious-cultural contexts and enlightened by contributions from ethnicity and religion...

Chronic myeloid leukemia (CML) is a hematological stem cell cancer driven by BCR-ABL1 fusion protein. We review the previous and recent evidence on the significance of CML in diagnostic and clinic management. The technical monitoring of BCR-ABL1 with quantitative real time-PCR has been used in assessing patient outcome. The cytogenetic mark of CML is Philadelphia chromosome, that is formed by reciprocal chromosomal translocations between human chromosome 9 and 22, t(9:22) (q(34):q(11)). It makes a BCR-ABL1 fusion protein with an anomaly tyrosine kinase activity that promotes the characteristic proliferation of progenitor cells in CML and acute lymphoblastic lymphoma...

REVIEW
Huyen Trang Ha Thi, Suntaek Hong
Chronic inflammation is a critical modulator of carcinogenesis through secretion of inflammatory cytokines, which leads to the formation of an inflammatory microenvironment. In this process, the inflammasome plays an important role in the expression and activation of interleukin (IL)-1β and IL-18 to promote cancer development. The inflammasome is a multiprotein complex consisting of several nucleotide-binding domain and leucine-rich repeat containing receptor, adaptor proteins, and caspase 1 (CASP1). It senses the various intracellular (damage-associated molecular patterns) and extracellular (pathogen-associated molecular patterns) stimuli...

Helicobacter pylori is a dominant bacterium living in the human gastric tissues. In H. pylori-infected tissues, the infiltrated inflammatory cells produce reactive oxygen species (ROS), leading to gastric inflammation with production of various mediators. According to numerous epidemiological studies, dietary carotenoids may prevent gastric inflammation due to their antioxidant properties. Recent studies showed that antioxidant and anti-inflammatory effects of astaxanthin and β-carotene may contribute to inhibition of H...
