## Abstract ## Background Because of the known property of less aggressiveness of differentiated cells compared to immatured cells all attempts are made to elucidate whether differentiation inducers possibly could be applied for neuroblastoma therapy. We are interested in examining the influence o

โฆ Synopsis
The effect of butyric acid (BA) and all trans-retinoic acid (RA) on murine melanoma cells was investigated in vitro and in vivo. The in vitro assays included 3H-IdUR incorporation, adhesion, migration and invasion experiments. Butyric acid decreased 3H-IdUR cellular incorporation within 24h and increased adhesion as measured by trypsin release of 3H-IdUR labelled cells from either polycarbonate (p.c.) or Matrigel-coated p.c. membranes. Migration and invasion rates after 72 h were quantified by scanning electron microscopy (SEM). The invasion barrier consisted of Matrigel-coated p.c. membranes. Butyric acid significantly enhanced migration and invasion of B16a cells, while RA significantly decreased migration and invasion of B16a and K-1735 ceils. Subcutaneous administration of either BA or RA pellets significantly decreased the number of lung nodules in the experimental metastatic assay. The experimental metastatic assay is defined as a tail vein inoculation protocol followed by subsequent lung evaluation.
