Cicero, Tullia, and Marcus: Gender-Specific Concerns for Family Tradition?

A fair number of Cicero's letters reveal his concern for his daughter Tullia and his son Marcus. Recent scholarship has read these letters as evidence for a ‘natural’ emotional attachment of a father to his children, in reaction to Philippe Ariès's opposite claim. This chapter considers whether Cicero's letters can be analysed only as expressions of paternal affection. The fact that the pater familias Cicero occupies a political position simultaneously in his nuclear family, his domus, and the Senate, results in a concern for his prestige within the social field of the aristocracy. And this concern is necessarily conferred upon his support of the education and the social and political career of his children. The chapter traces the gender-specific differences between Cicero's treatment of Tullia and Marcus, shows the social construction of parental affection, and contributes to a further understanding of the different functions of daughters and sons in the social force field of family memory.

Connexin genes in the mouse and human genome

Gap junctions serve for direct intercellular communication by docking of two hemichannels in adjacent cells thereby forming conduits between the cytoplasmic compartments of adjacent cells. Connexin genes code for subunit proteins of gap junction channels and are members of large gene families in mammals. So far, 17 connexin (Cx) genes have been described and characterized in the murine genome. For most of them, orthologues in the human genome have been found (see White and Paul 1999; Manthey et al. 1999; Teubner et al. 2001; Söhl et al. 2001). We have recently performed searches for connexin genes in murine and human gene libraries available at EMBL/Heidelberg, NCBI and the Celera company that have increased the number of identified connexins to 19 in mouse and 20 in humans. For one mouse connexin gene and two human connexin genes we did not find orthologues in the other genome. Here we present a short overview on distinct connexin genes which we found in the mouse and human genome and which may include all members of this gene family, if no further connexin gene will be discovered in the remaining non-sequenced parts (about 1-5%) of the genomes.
