Prolactin Effects and Regulation of its Receptors in Human Mammary Tumor Cellswth regulation. The possible physiological role of other hormones, particularly prolactin, in the etiology and progression of this disease is not as well established. However, the use of several rodent model systems has established that this lactogenic hormone plays an important role in the inductio

Indeed, the transforming genes of a number of tumor cells and viruses have been identified as genes for growth factors or receptors (1,2). Our aim here i

Hormonal Control of Mouse Mammary Tumor Virus Transcriptionaracterized retroviruses, yet MMTV is not completely analogous to the other viruses (1). Some of its unique features have attracted considerable attention in the past few years. First, MMTV transcription is regulated by glucocorticoid hormones. The isolation of MMTV proviruses by gene cloning follow

MMTV contains a single-stranded genomic RNA with a sedimentation coefficient of between 60–70S and a molecular mass of 6.45 x 10.daltons, (1,2). This virion-contained RNA consists of two subunits (35S), each with molecular masses of 2.93 x 10.d
