The purpose of this study was to identify the effects of Neurofeedback(NF), Cranio-Sacral Therapy(CST) and Combine Therapy(CT) in middle aged women through their experiences after participating these therapies. The participants were 53 middle aged women who lived in S city, 17 in the NF group, 17 in the CST and 19 in the CT, for 10 weeks from October to December, 2007. The NF group had 30 sessions, the CST group had 10 sessions and the CT group had 30 sessions of NF training after 10 sessions of CST. The data was collected from daily chart by self reporting their experiences during sessions. Collected data was analyzed by content analysis. From raw data, 37 items of NF, 91 items of CST and 110 items of CT were extracted in the content analysis. Similar items were gathered to 22 attributes of NF, 63 of CST and 68 of CT. These attributes were categorized into 9 higher attributes. The dominant attributes of NF were doziness during the training, mental comfort, lightening of physical and mental condition. Mental and physical comfort, improvement of sleep, healthy condition, crying were the dominant of CST. Also mental and physical comfort, lightening of physical condition, improvement of sleep, tear were the dominant of CT. According to the results of this study NF, CST and CT were very effective on physical and psychological relaxation. Therefore it is recommended that these NF, CST and CT be used as a complementary and alternative medicine(CAM) in middle aged women.

목적 : 이 연구는 봉독이 NF-${\kappa}$B의 활성억제를 통하여 전립선 암세포주인 DU-145 세포의 성장을 억제하 는지를 확인하고 그 기전을 살펴보고자 하였다. 방법 : 봉독을 처리한 후 DU-145의 성장억제를 관찰하기 위해 WST-1 assay를 시행하였고, 세포자멸사의 관찰에는 DAPI staining assay를 통한 세포형태관찰을 시행하였으며, 염증관련유전자 발현 관찰에는 western blot analysis를 시행하였고, 세포자멸사와 연관된 NF-${\kappa}$B의 활성 변화를 관찰하기 위해 EMSA와 luciferase assay를 시행하였으며, DU-145에서 봉독과 NF-${\kappa}$B의 상호작용을 관찰하기 위해 transient transfection assay를 시행하여 세포생존율과 NF-${\kappa}$B의 활성 변동을 측정하였다. 결과 : DU-145 세포에서 봉독을 처리한 후 세포성장이 억제되었으며, 염증관련유전자 발현 및 NF-${\kappa}$B의 활성의 유의한 감소를 나타내었다. DU-145 세포에서 NF-${\kappa}$B의 p50와 IKK들을 치환하여 작용기를 없애고 봉독을 처리하였을 경우에도 세포활성 및 NF-${\kappa}$B의 활성의 유의한 감소를 나타내었다. 결론 : 이상의 결과는 봉독이 NF-${\kappa}$B의 활성 억제를 통하여 인간 전립선암세포주인 DU-145의 세포자멸사를 유발함으로써 증식억제 효과가 있음을 입증한 것으로 전립선암의 예방과 치료에 대한 효과적인 치료제 개발에 도움이 될 것으로 기대된다. 다만 그 기전에서 봉독은 기존연구와 같은 NF-${\kappa}$B p50 및 IKK들의 작용기와 상호작용 이외에 다른 기전이 관여되는 것으로 심화 연구를 요한다.

We previously found that cobrotoxin inhibited $NF-{\kappa}B$ activity by reacting with signal molecules of $NF-{\kappa}B$ which is critical contributor in cancer cell growth by induction of apoptotic cell death. We here investigated whether cobrotoxin inhibits cell growth of human prostate cancer cells through induction of apoptotic cell death, which is related with the suppression of the $NF-{\kappa}B$ activity. Cobrotoxin $(0{\sim}8\;nM)$ inhibited prostate cancer cell growth through increased apoptosis in a dose dependent manner. Cobrotoxin inhibited DNA binding activity of $NF-{\kappa}B$, an anti-apoptotic transcriptional factor. Consistent with the induction of apoptosis and inhibition of $NF-{\kappa}B$, cobrotoxin increased the expression of pro-apoptotic proteins caspase 3. Cobrotoxin, a venom of Vipera lebetina turanica, is a group of basicpeptides composed of 233 amino acids with six disulfide bonds formed by twelve cysteins. NF-kB is activated by subsequent release of inhibitory IkB and translocation of p50. Since sulfhydryl group is present in kinase domain of p50 subunit of NF-kB, cobrotoxin could modify NF-kB activity by protein-protein interaction. And Cobrotoxin down regulated Akt signals. Salicylic acid as a reducing agent of Sulf-hydryl group and LY294002 as a Akt inhibitor abrogated cobrotoxin-induced cell growth and DNA binding activity of $NF-{\kappa}B$. These findings suggest that nano to pico molar range of cobrotoxin could inhibit prostate cancer cell growth, and the effect may be related with the induction of apoptotic cell death through Akt dependent inhibition of $NF-{\kappa}B$ signal.

NF1 proteins are a family of DNA binding proteins which consist of two separate domains, N-terminal DNA binding domain and C-terminal transcription activation domain. The N-terminal 220 amino acids are highly conserved and are also known to mediate dimerization of NF1 proteins. The C-terminal regions of different type of NF1 proteins are heterogeneous and responsible for transcriptional activation. In this study, we tested the interaction between different domains of rat NF1-A protein by yeast two hybrid analysis and observed the interaction between C-terminal regions of NF1-A which do not contain the N-terminal dimerization domain. Our results showed that the C-terminal region of rat NF1-A between residues 231 and 509 strongly interacted not only with itself, but also with human NF1/CTF1 which is a different type of NF1. When the C-terminal region was divided into two fragments, one from residue 231 to 447 and the other from 448 to 509, the two fragments were able to interact with the C-terminal region of NF1-A significantly. This indicates that both fragments contain independent interaction domains. Analysis of the interactions with alanine substituted fragments showed that substitutions of the heptasequence, SPTSPTY of NF1-A, affected interaction between NF1 proteins. Our results strongly suggest that C-terminal regions may also be important for the formation of homo- and heterodimers in addition to the N-terminal dimerization domain. Also, the heptasequence motif may play some roles in dimer formation.

Neurofilaments (NFs) are neuronal intermediate filaments composed of light (NF-L), middle (NF-M), and heavy (NF-H) subunits. NF-L self-assembles into a "core" filament with which NF-M or NF-H co-assembles to form the neuronal intermediate filament. Recent reports show that point mutations of the NF-L gene result in Charcot-Marie-Tooth disease (CMT). However, the most recently described rod domain mutant of human NF-L (A148V) has not been characterized in cellular level. We cloned human NF-L and used it to engineer the A148V. In phenotypic analysis using SW13 cells, A148V mutation completely abolished filament formation despite of presence of NF-M. Moreover, A148V mutation reduced the levels of in vitro self-assembly using GST-NF-L (H/R) fusion protein whereas control (A296T) mutant did not affect the filament formation. These results suggest that alanine at position 148 is essentially required for NF-L self-assembly leading to subsequent filament formation in neuronal cells.

NF-κB acts as a critical transcription factor for the survival of cells via the induction of antiapoptotic genes. Constitutive activation of NF-κB in many types of solid tumors suggests that the inhibition of NF-κB might prevent or inhibit tumorigenesis. Although a number of studies demonstrated that Hsp70 regulated NF-κB activity, the exact mechanism is not clear. This study investigated the functional relationship of Hsp70 and IKKγ in the regulation of NF-κB activation using expression plasmids of components of the IKK complex. Wild-type and deletion mutants of IKKγ were expressed together with Hsp70, and the combined regulatory effect of Hsp70 and IKKγ on NF-κB activation was assayed. Hsp70 suppressed the activation of NF-κB in a reporter plasmid assay. Hsp70 also suppressed the phosphorylation and degradation of IκBα. The suppressive effect of Hsp70 on NF-κB activation was synergistically elevated by IKKγ. The N-terminal IKKβ binding site, C-terminal leucine zipper, and zinc finger domains of IKKγ were not necessary for the suppressive effect. Furthermore, Hsp70 and IKKγ synergistically suppressed the induction of COX-2 expression by lipopolysaccharides in RAW264.7 cells. These results suggest that overexpression of Hsp70 and IKKγ may be a strategic method for inhibition of NF-κB and related diseases.

This study was to investigate the effect of the extract(KP-HE) from Kalopanax pictus(KP) fermented with Hericium erinaceum(HE) mycelium on oxidative modification of neurofilament-L(NF-L) which is closely related to neurodegenerative disorders. The oxidative modification of NF-L was induced by AAPH producing peroxyl radicals in solution, and KP, HE, and KP-HE was investigated. KP and HE did not protect NF-L against peroxyl radical-mediated NF-L modification whereas KP-HE significantly prevented NF-L modification induced by peroxyl radical. KP-HE inhibited the formation of dityrosine in oxidative modification of NF-L and stimulated the peroxyl radical scavenging activity. The effects of KP, HE, and KP-HE on the modification of NF-L by tetrahydropapaveroline(THP), a neurotoxin found in patients with Parkinson's disease was investigated. KP-HE also prevented THP-mediated NF-L modification as compared to KP and HE. In addition, KP-HE significantly inhibited the formation of dityrosine in oxidative modified NF-L and enhanced the inhibition of reactive oxygen species(ROS) was generated by THP. The results suggested that KP-HE can contribute to protected cell from oxidative stress was induced by ROS and neurotoxin. Therefore, KP-HE could potentially be used as a valuable functional food ingredient to prevent neurodegenerative disorders.
