Hypoxia-inducible factor-1 (HIF-1), a transcription factor composed of two subunits (HIF-1alpha and HIF-1beta), initially described as a mediator of adaptive responses to changes in tissue oxygenation, has been shown to be activated in an oxygen-inde

Insulin-dependent diabetes mellitus is associated with decreased levels of circulating insulin-like growth factor binding protein-3 (IGFBP-3), which are restored toward normal by treatment with insulin and/or infusion of insulin-like growth factor-I

The insulin-like growth factors (IGFs) are potent mitogens with both endocrine and autocrine-paracrine effects on cell growth. The IGF binding proteins (IGFBPs) are found in many human biological fluids and in the conditioned media of many cell cultu

The low mol wt insulin-like growth factor-binding protein (IGFBP-1) originally isolated from amniotic fluid has been considered to be GH independent. In this report we have examined the effect of GH on hepatic IGFBP-1 expression in the hypophysectomi

Alternative splicing of insulin-like growth factor I (IGF-I)/somatomedin C mRNAs generates two IGF-I mRNAs coding for IGF-I peptides with different sequences in the E domain of the IGF-I prohormone. These two mRNAs encode alternative E peptides due t

Since sex steroid hormones and growth factors are known to modulate the proliferation of breast tumors, we have studied the effects of estrogen and progestin, their antagonists, and growth factors on the regulation of estrogen receptor (ER) mRNA and

In MCF7 human breast cancer cells, cathepsin-D and pS2 mRNAs are specifically and directly induced by estrogens at the transcriptional level. We studied the regulation of expression of these two genes by growth factors that are also mitogenic in this

To obtain information about the functional significance of the structural heterogeneity that has been described for rat insulin-like growth factor I (IGF-I) cDNAs, we hybridized polyadenylated RNAs from rat tissues at different developmental stages w
