In Roman mythology, Janus was the god of gates, doors, beginnings and endings. He was usually depicted with two faces looking in opposite directions. Janus was frequently used to symbolize change and transitions, such as the progression from past to future or from one viewpoint to another. 2,4-dinitrophenol (DNP) and other nitrophenols have long been known to be toxic at high concentrations (the 'bad' face of DNP), an effect that appears essentially related to interference with cellular energy metabolism due to uncoupling of mitochondrial oxidative phosphorylation.

Lipocalins are a family of proteins characterized by a conserved eight-stranded ?-barrel structure with a ligand-binding pocket. They perform a wide range of biological functions and this functional multiplicity must relate to the lipid partner involved. Apolipoprotein D (ApoD) and its insect homologues, Lazarillo (Laz) and neural Lazarillo (NLaz), share common ancestral functions like longevity, stress resistance and lipid metabolism regulation, coexisting with very specialized functions, like courtship behavior.

Recent advances in somatic cell reprogramming have highlighted the plasticity of the somatic epigenome, particularly through demonstrations of direct lineage reprogramming of adult mouse and human fibroblasts to induced pluripotent stem cells (iPSCs) and induced neurons (iNs) under defined conditions. However, human cells appear to be less plastic and have a higher epigenetic hurdle for reprogramming to both iPSCs and iNs. Here, we show that SH2B adaptor protein 1?

Sprouty proteins are regulators of cell growth and branching morphogenesis. Unlike mouse Spry3, which is X-linked, human SPRY3 maps to the pseudoautosomal region 2; however, the human Y-linked allele is not expressed due to epigenetic silencing by an unknown mechanism. SPRY3 maps adjacent to X-linked Trimethyllysine hydroxylase epsilon (TMLHE), recently identified as an autism susceptibility gene. We report that Spry3 is highly expressed in central and peripheral nervous system ganglion cells in mouse and human, including cerebellar Purkinje cells and retinal ganglion cells.

We studied the effects of natural essential oil on neurite outgrowth in PC12m3 neuronal cells to elucidate the mechanism underlying the action of the oils used in aromatherapy. Neurite outgrowth can be induced by nerve growth factor (NGF), where ERK and p38 MAPK among MAPK pathways play important roles in activating intracellular signal transduction. In this study, we investigated whether d-limonene, the major component of essential oils from oranges, can promote neurite outgrowth in PC12m3 cells, in which neurite outgrowth can be induced by various physical stimulations.

The effects of an ayurvedic compound (MAK-5) alone or together with nerve growth factor (NGF) on the neurite outgrowth of PC12 cells was studied. PC12 cells treated with NGF alone showed a clear neurite outgrowth with a decrease of the proliferation at the dose higher than 5 ng/ml. MAK-5 alone does not induce significant neurite outgrowth in the PC12 cells and does not decrease the proliferation.

Axonal regeneration is important for functional recovery following nerve damage. Centella asiatica Urban herb, also known as Hydrocotyle asiatica L., has been used in Ayurvedic medicine for centuries as a nerve tonic. Here, we show that Centella asiatica ethanolic extract (100 microg mL-1) elicits a marked increase in neurite outgrowth in human SH-SY5Y cells in the presence of nerve growth factor (NGF). However, a water extract of Centella was ineffective at 100 microg mL-1.

Increasing evidences implicate impairment of axonal integrity in mechanisms underlying neurodegenerative disorders. Beta-boswellic acid (BBA) is the major component of Boswellia serrata gum. This resin has long been used in Ayurveda (India's traditional medicine) to prevent amnesia. In this study, the effect of BBA was examined on neurites outgrowth and branching as well as on polymerization dynamics of tubulin. The morphometric parameters (axonal length and neuritis branching) were examined microscopically after treating the hippocampal cells with BBA.

ETHNOPHARMACOLOGICAL RELEVANCE: Moringa oleifera Lam. (Moringaceae) by virtue of its high nutritional as well as ethnomedical values has been gaining profound interest both in nutrition and medicinal research. The leaf of this plant is used in ayurvedic medicine to treat paralysis, nervous debility and other nerve disorders. In addition, research evidence also suggests the nootropic as well as neuroprotective roles of Moringa oleifera leaf in animal models.

The formation of polyglutamine-containing aggregates and inclusions are hallmarks of pathogenesis in Huntington's disease that can be recapitulated in model systems. Although the contribution of inclusions to pathogenesis is unclear, cell-based assays can be used to screen for chemical compounds that affect aggregation and may provide therapeutic benefit. We have developed inducible PC12 cell-culture models to screen for loss of visible aggregates.
