The evolutionarily conserved kelch-repeat protein muskelin was identified as an intracellular mediator of cell spreading. We discovered that its morphological activity is controlled by association with RanBP9/RanBPM, a protein involved in transmembrane signaling and a conserved intracellular protein complex. By subcellular fractionation, endogenous muskelin is present in both the nucleus and the cytosol. Muskelin subcellular localization is coregulated by its C terminus, which provides a cytoplasmic restraint and also controls the interaction of muskelin with RanBP9, and its atypical lissencephaly-1 homology motif, which has a nuclear localization activity which is regulated by the status of the C terminus. Transient or stable short interfering RNA–based knockdown of muskelin resulted in protrusive cell morphologies with enlarged cell perimeters. Morphology was specifically restored by complementary DNAs encoding forms of muskelin with full activity of the C terminus for cytoplasmic localization and RanBP9 binding. Knockdown of RanBP9 resulted in equivalent morphological alterations. These novel findings identify a role for muskelin–RanBP9 complex in pathways that integrate cell morphology regulation and nucleocytoplasmic communication.

Effective Role

Aluminium foams are of interest due to their ultra low density, high structural stiffness per unit weight. Like conventional Al foams having Ca, ceramic particle (e.g. SiC, Al2O3) containing Al alloy metal matrix composite (MMC) foams can be produced. In this approach, parameters such as particle type, size, and volume fraction need to be optimized to get good quality foams with high foam expansions. However, the role of them on the compression properties of MMC foams is seldom reported. With this objective, the present study explores the effect of SiCP size and vol. % on compression behavior of various Al-Si/SiCP foams prepared at DMRL. From the large number of compression tests, it is observed that the reinforcement parameters don’t seem to play any effective role with respect to foam properties, although they are very important in foam manufacture.

Stimulating Factor

Differentiating human adipose-derived stem cells (ASCs) towards Schwann cells produces an unstable phenotype when stimulating factors are withdrawn. Here, we set out to examine the role of glial growth factor 2 (GGF-2) in the maintenance of Schwann-like cells. Following ASC differentiation to Schwann-like cells, stimulating factors were withdrawn such that cells either remained in media supplemented with all stimulating factors, GGF-2 alone, or underwent complete withdrawal of all factors. Furthermore, each stimulating factor was also removed from the growth medium individually. At 72 hours, gene (qRT-PCR) and protein (ELISA) expression of key Schwann cell factors were quantified and cell morphology was analysed. Cells treated with GGF-2 alone reverted to a stem cell morphology and did not stimulate the production of brain-derived neurotrophic factor (BDNF), regardless of the concentration of GGF-2 in the growth medium. However, GGF-2 alone increased the expression of Krox20, the main transcription factor involved in myelination, relative to those cells treated with all stimulating factors. Cells lacking fibroblast growth factor were unable to maintain a Schwann-like morphology, and those lacking forskolin exhibited a downregulation in BDNF production. Therefore, it is likely that the synergistic action of multiple growth factors is required to maintain Schwann-like phenotype in differentiated ASCs.
