  1. About OMICS Group OMICS Group International is an amalgamation of Open Access publications and worldwide international science conferences and events. Established in the year 2007 with the sole aim of making the information on Sciences and technology ‘Open Access’, OMICS Group publishes 400 online open access scholarly journals in all aspects of Science, Engineering, Management and Technology journals. OMICS Group has been instrumental in taking the knowledge on Science & technology to the doorsteps of ordinary men and women. Research Scholars, Students, Libraries, Educational Institutions, Research centers and the industry are main stakeholders that benefitted greatly from this knowledge dissemination. OMICS Group also organizes 300 International conferences annually across the globe, where knowledge transfer takes place through debates, round table discussions, poster presentations, workshops, symposia and exhibitions.

  2. About OMICS Group Conferences OMICS Group International is a pioneer and leading science event organizer, which publishes around 400 open access journals and conducts over 300 Medical, Clinical, Engineering, Life Sciences, Phrama scientific conferences all over the globe annually with the support of more than 1000 scientific associations and 30,000 editorial board members and 3.5 million followers to its credit.

  5. Effects of Neurotrophins Neurotrophins (NGF, BDNF, NT-3, NT-4/5 ) Neuronal stem cells Differentiation Neuronal precursor cells Development Maturation Ageing Death Astrocyte Neurons Oligodendrocyte

  6. Neurotrophic factors • Representative neurotrophic factors • ・NGF • ・ BDNF • ・ NT-3, NT-4/5 • Problems due to large peptide molecule • ・No penetration of B.B.B. • ・Poor oral pharmacokinetic profiles • ・Immune reactions Nonpeptidyl small molecule neurotrophic compounds

  7. PC12 cells used for Screening neurotrophic/neuroprotective/cytotoxic compounds “The PC12 cell line was derived from rat pheochromocytoma, a tumor arising from chromaffin cells of the adrenal medulla. It is a useful model for studying cell signaling for at least two reasons: (i) There are few growth factors, neurotrophins, and hormones to which it does not respond; and (ii) distinct responses of differentiation, proliferation, and survival can all be assessed independently.” Neuroprotectiveafter NGF withdrawal Science, 296(5573):1648 (2002) Neurotrophic Cytotoxic

  8. The Principles for Screening Neurotrophic/Neuroprotective Compounds in Rat Cortical Neurons Neurotrophic compounds can promote neurite outgrowth, which improves the status of neurons. Neuroprotective compounds can retard toxic factor-induced cell death in primary cultured neurons. Neurotrophic toxic

  14. Differentiation of PC12 Cells Induced by 1 and 2 Control (0.5 % EtOH) NGF (10ng/mL) 1 (30 μM) 2 (30 μM) PC12 cells were cultured in 24-well plates in DMEM + 10% HS and 5% FBS for 24 h at a density of2x103 cells/cm2, and then medium was changed to DMEM + 2% HS and 1% FBS containing1 and 2. After 4 days cells with neurites were counted. ## P<0.01 vs control; by Chi-square test

  15. Neurite Length of NGF-differentiated PC12 Cells Effected by 1 Average of neurite length (μm ) 1 PC12 cells were cultured in two 24-well plates in DMEM + 10% HS and 5% FBS for 24 h at a density of 2 x103 cells/cm2, and then medium was changed to DMEM + 2% HS and 1% FBS with NGF (10 ng/mL) containing 19 respectively. After 4 days neurite lengths of PC12 cells were quantified. Data are expressed as the mean ± SE (n= 150). **P < 0.01 vs control; Dunnett’s t test.
