IGF-Binding Proteins: Why Do They Exist and Why Are There So Many?
Frontiers in Endocrinology, 2018 Insulin-like growth factors (IGFs) are key growth-promoting peptides that act as both endocrine hormones and autocrine/paracrine growth factors. In the bloodstream and in local tissues, most IGF molecules are bound by one of the members of the IGF ...

Insulin-Like Growth Factor Receptor [PDF]
Journal of Thoracic Oncology, 2011 The insulin-like growth factor (IGF) signaling axis plays an essential role in the balance between cellular proliferation and apoptosis. Higher levels of IGF receptor are seen in lung tumor cells than normal tissue. IGF-1 receptor (IGFR-1R) and its ligand IGF-2 is overexpressed in non-small cell lung cancer (NSCLC).

Proteolysis of insulin-like growth factor binding proteins (IGFBPs) by calpain [PDF]
, 2005 Calpains are non-lysosomal, Ca2+-dependent cysteine proteases, which are ubiquitously distributed across cell types and vertebrate species. The rules that govern calpain specificity have not yet been determined.

Revisiting the IGF-1R as a breast cancer target
npj Precision Oncology, 2017 The type I insulin-like growth factor-1 receptor is a well-described target in breast cancer and multiple clinical trials examining insulin-like growth factor-1 receptor have been completed.

Insulin-Like Growth Factor II (IGF-II) Is More Potent Than IGF-I in Stimulating Cortisol Secretion from Cultured Bovine Adrenocortical Cells: Interaction with the IGF-I Receptor and IGF-Binding Proteins [PDF]
, 1995 Although the stimulating effect of insulin-like growth factor I (IGF-I) on adrenal steroidogenesis has been well established, the role of IGF-II in the adult adrenal gland remains unknown.

Journal of Medical Case Reports, 2021 Background Adjuvant endocrine therapy is recommended for the treatment of hormone-receptor-positive breast cancer. Aromatase inhibitors are associated with significant musculoskeletal adverse effects, likely through growth hormone/insulin-like growth ...

Frontiers in Endocrinology, 2022 The growth hormone/insulin-like growth factor (GH/IGF) system, also called the pituitary-liver axis, has a somatotrophic role in the body. Although the GH/IGF system has always been regarded as a vertebrate-specific endocrine system, its actual origin ...

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo. [PDF]
FEBS Open BioTo test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

IGF-I receptor phosphorylation is impaired in cathepsin X-deficient prostate cancer cells [PDF]
, 2012 The cysteine-type peptidase cathepsin X is highly upregulated in several cancers and presumably promotes tumor invasion through bypassing cellular senescence. Here, we present first evidence that the underlying mechanism may involve the regulation of the
