  • Chronic inflammation has been shown to be closely associated with tumor development and progression. Nuclear factor kappa B (NF-κB) is composed of a family of five transcription factors. NF-κB signaling plays a crucial role in the inflammatory response and is often found to be dysregulated in various types of cancer, making it an attractive target in cancer therapeutics. In this study, CDC-like kinase 3 (CLK3) was identified as a novel kinase that regulates the NF-κB signaling pathway. Our data demonstrate that CLK3 inhibits the canonical and non-canonical NF-κB pathways. Luciferase assays following the transient or stable expression of CLK3 indicated that this kinase inhibited NF-κB activation mediated by Tumor necrosis factor-alpha (TNFα) and Phorbol 12-myristate 13-acetate (PMA), which are known to activate NF-κB signaling via the canonical pathway. Consistent with data on the ectopic expression of CLK3, CLK3 knockdown using shRNA constructs increased NF-κB activity 1.5-fold upon stimulation with TNFα in HEK293 cells compared with the control cells. Additionally, overexpression of CLK3 suppressed the activation of this signaling pathway induced by NF-κB-inducing kinase (NIK) or CD40, which are well-established activators of the non-canonical pathway. To further examine the negative impact of CLK3 on NF-κB signaling, we performed Western blotting following the TNFα treatment to directly identify the molecular components of the NF-κB pathway that are affected by this kinase. Our results revealed that CLK3 mitigated the phosphorylation/activation of transforming growth factor-α-activated kinase 1 (TAK1), inhibitor of NF-κB kinase alpha/beta (IKKα/α), NF-κB p65 (RelA), NF-κB inhibitor alpha (IκBα), and Extracellular signal-regulated kinase 1/2-Mitogen-activated protein kinase (ERK1/2-MAPK), suggesting that CLK3 inhibits both the NF-κB and MAPK signaling activated by TNFα exposure. Further studies are required to elucidate the mechanism by which CLK3 inhibits the canonical and non-canonical NF-κB pathways. Collectively, these findings reveal CLK3 as a novel negative regulator of NF-κB signaling.

  • Epigenetic is usually referring to heritable traits that do not involve changes to the underlying DNA sequence. DNA methylation is known to serve as cellular memory. and is one of the most important mechanism of epigenetic. DNA methylation is a covalent modification in which the target molecules for methylation in mammalian DNA are cytosine bases in CpG dinucleotides. The 5' position of cytosine is methylated in a reaction catalyzed by DNA methyltransferases; DNMTl, DNMT3a, and DNMT3b. There are two different regions in the context of DNA methylation: CpG poor regions and CpG islands. The intergenic and the intronic region is considered to be CpG poor, and CpG islands are discrete CpG-rich regions which are often found in promoter regions. Normally, CpG poor regions are usually methylated whereas CpG islands are generally hypomethylated. DNA methylation is involved in various biological processes such as tissue-specific gene expression, genomic imprinting, and X chromosome inactivation. In general. cancer cells are characterized by global genomic hypomethylation and focal hypermethylation of CpG islands, which are generally unmethylated in normal cells. Gene silencing by CpG hypermethylation at the promotors of tumor suppressor genes is probably the most common mechanism of tumor suppressor inactivation in cancer.

  • It is said that the reason Bulgarians enjoy longevity is that they have a lot of yogurt, whose $Lactobacillus$ controls intestinal poison-producing germs. In young individuals, the number of bifidobacteria exceeds 10 billion per 1 g of intestinal content, but this number decreases for older or senile individuals, who have a larger number of harmful microorganisms such as $Clostridium$. In addition, it is well known that artificially increasing intestinal bifidobacteria can help control harmful microorganisms and thus facilitate a healthier and longer life. The microorganisms used for artificial spawn are referred to as probiotic microorganisms, and in general, lactic acid bacteria(LAB) are used. Unlike antibiotics, which kill harmful microorganisms, probiotic microorganisms coexist with and control them, while improving the health of the individual, that is, they can improve and invigorate host cells. Because probiotic microorganisms and its products based on LAB are known to help prevent and treat constipation, diarrhea, intestinal inflammation, and blood cholesterol and generally improve health through the purification of intestines, its market has been continuously expanding. Korea imports approximately 90% of spawn and uses them. It is likely that they are not appropriate for Korean's physical condition. Thus, considering this problem into account, Entecbio, a biotech firm in Korea, has produced various products by using its proprietary microorganisms. In this paper, the effects, characteristics, and kinds of products from based on proprietary microorganisms, with its prospect for market, etc., are generally examined.

  • Two years ago, a 75-year-old female was diagnosed left renal cancer and went on radical nephrectomy. Recently, metastatized lesions on lumbar spine and various lymph nodes including paraaortic lymph node of which diameter was about 5.5 cm was identified. She suffered from extreme low back pain despite using opioid agents of fentanyl patch and oral oxycodone. During about one month, Korean medicine therpies including herbal medicine(Yang-He tang), acupuncture with her conventional medications were co-administered. However her pain didn't improved and gradual cough and dyspnea developed. So she transferred to the hemato-oncology part for 2 weeks under the diagnosis of everolimus-induced noninfectious pneumonitis. After quitting everolimus her pneumonitis was improved and she came back our ward and started another herbal medicine, Ai-Tong-Ning tang for about 2 months. During this period, her pain was well managed without oral opioid agents and her paraaortic lymph node was regressed to about 2.2cm in diameter.

  • Conventional CT and MRI scans produce cross-section slices of body that are viewed sequentially by radiologists who must imagine or extrapolate from these views what the 3 dimensional anatomy should be. By using sophisticated algorithm and high performance computing, these cross-sections may be rendered as direct 3D representations of human anatomy. The 2D medical image analysis forced to use time-consuming, subjective, error-prone manual techniques, such as slice tracing and region painting, for extracting regions of interest. To overcome the drawbacks of 2D medical image analysis, combining with medical image processing, 3D visualization is essential for extracting anatomical structures and making measurements. We used the gray-level thresholding, region growing, contour following, deformable model to segment human organ and used the feature vectors from texture analysis to detect harmful cancer. We used the perspective projection and marching cube algorithm to render the surface from volumetric MR and CT image data. The 3D visualization of human anatomy and segmented human organ provides valuable benefits for radiation treatment planning, surgical planning, surgery simulation, image guided surgery and interventional imaging applications.

  • Purpose: This study aims to identify factors that influence middle-aged men's attitude towards death. Methods: The study enrolled 204 middle-aged (range=40~59 years) male residents of Daegu in Korea. Using a structured questionnaire, data were collected in October 4~30, 2010. For data analysis, we used descriptive statistics, t-test, one-way ANOVA, Scheff$\grave{e}$'s test, Pearson correlation coefficient, and stepwise multiple regression with SPSS WIN 14.0. Results: Participants' attitude towards death significantly differed according to educational level, religion, volunteer activities, and perceived health status. Moreover, their attitude towards death was negatively correlated with life stress and depression and positively correlated with self-esteem, life satisfaction, and coping behavior. The factors influencing the attitude towards death were life satisfaction, daily stress, religion, and depression, which explained approximately 25.7% of the total variance. Conclusion: Middle-aged men perform a crucial role in our society, and their attitude toward death affects how they cope with a situational crisis such as a terminal cancer or withdrawal of life sustaining treatment. Therefore, it is necessary to develop and implement a support program for middle-aged men, which offers them with various strategies to better manage their daily stress and improve their life satisfaction and coping skills.

  • This study tested the antioxidant activities and anti-aging effects of an extract of Orostachys japonicus, a herb used as a folk remedy for cancer for a long time. To assess the antioxidant activities of the Orostachys japonicus extract (OJE), the total polyphenol content was confirmed to have a high caffeic acid equivalent weight of 12 g by dry weight of 100g OJE and the total flavonoid content was confirmed that the quercetin equivalent of 1.7 g by dry weight of 100g OJE. DPPH free radical scavenging activity was confirmed a high scavenging activity of 79.7% at a concentration of 1%. To confirm the anti-aging effect of OJE, MMP-1 expression was decreased in $25{\mu}L/mL$ and $50{\mu}L/mL$ similar to control. In a clinical experiment, a group of subjects who used a cosmetic product containing OJE showed a significant increase in the amount of skin moisture from the forehead, left cheek, and chin. The experimental group showed a significant increase in the amount of skin sebum from the chin and maintaining pH balance of normal skin, As a result, the OJE demonstrates the efficacy of natural cosmetic material as antioxidant and anti-aging.
