The homeobox (HOX) genes encoding an evolutionarily highly conserved family of homeodomain-containing transcriptional factors are essential for embryogenesis and tumorigenesis.HOX genes are involved in cell identity determination during early embryonic development and postnatal processes.The deregulation of HOX genes is closely associated with nume
A commonly held view in evolutionary biology is that speciation (the emergence of genetically distinct and reproductively incompatible subpopulations) is driven by external environmental constraints, such as localized barriers to dispersal or habitat-based variation in selection pressures.We have developed a spatially explicit model of a biological
Introduction: Adenoid Foot Cream cystic carcinoma (ACC) is an uncommon malignant tumour arising from salivary glands.It is more common in minor salivary glands, palate being the commonest site.Local recurrence, distant metastasis and perineural invasion are the common clinico-pathological features of this tumour.ACC of nasal septum and pterygo-pala
