IGF-1 receptor activity in the Golgi of migratory cancer cells depends on adhesion-dependent phosphorylation of Tyr1250 and Tyr1251 [PDF]
Although insulin-like growth factor 1 (IGF-1) signaling promotes tumor growth and cancer progression, therapies that target the IGF-1 receptor (IGF-1R) have shown poor clinical efficacy.

CLINICAL AND HORMONAL MILIEU OF 9 PATIENTS WITH PRIMARY GROWTH HORMONE INSENSITIVITY SYNDROME AND THEIR RESPONSE TO IGF-I GENERATION TEST [PDF]
Primary growth hormone insensitivity syndrome (GHIS) is a rare entity which can be due to defects in growth hormone (GH) receptor that is called type 1 Laron syndrome (T1LS) or post receptor defects (type 2 Laron syndrome ).

Overview: Increased signaling of the insulin-like growth factor (IGF) system via alterations in expression levels of its components has been demonstrated in various tumor types. Numerous experimental studies have supported the involvement of the IGF system signaling axis in tumor initiation and progression.

Des(1–3)IGF‐1 Treatment Normalizes Type 1 IGF Receptor and Phospho‐Akt (Thr 308) Immunoreactivityin Predegenerative Retina of Diabetic Rats [PDF]
Little is known about interventions that may prevent predegenerative changes in the diabetic retina. This study tested the hypothesis that immediate, systemic treatment with an insulin‐like growth factor (IGF)‐1 analog can prevent abnormal accumulations of type 1 IGF receptor, and phospho‐Akt (Thr 308) immunoreactivity in predegenerative retinas of ...

GnRH receptor activation competes at a low level with growth signaling in stably transfected human breast cell lines [PDF]
Breakthrough Breast CancerBackground: Gonadotrophin releasing hormone (GnRH) analogs lower estrogen levels in pre-menopausal breast cancer patients. GnRH receptor (GnRH-R) activation also directly inhibits the growth of certain cells.

Olmesartan potentiates the anti-angiogenic effect of sorafenib in mice bearing Ehrlich's ascites carcinoma: role of angiotensin (1-7). [PDF]
Local renin-angiotensin systems exist in various malignant tumor tissues; this suggests that the main effector peptide, angiotensin II, could act as a key factor in tumor growth.

Re-expression of IGF-II is important for beta cell regeneration in adult mice [PDF]
Background The key factors which support re-expansion of beta cell numbers after injury are largely unknown. Insulin-like growth factor II (IGF-II) plays a critical role in supporting cell division and differentiation during ontogeny but its role in the

The insulin-like growth factor (IGF)-1 signaling is relevant in regulating cell growth and cytokine secretions by glioblastomas. MicroRNAs determine the cell fate in glioblastomas. However, relationships between IGF-1 signaling and miRNAs in glioblastoma

Triple-negative breast cancers have a poor prognosis and are not amenable to endocrine- or HER2-targeted therapies. The prevailing view is that targeting the insulin-like growth factor (IGF) signal transduction pathway will not be beneficial for triple ...

Insulin-Like Growth Factor (IGF) Binding Protein-3 Interacts with the Type 1 IGF Receptor, Reducing the Affinity of the Receptor for its Ligand: An Alternative Mechanism in the Regulation of IGF Action [PDF]
With a view to determining the mechanisms by which insulin-like growth factor binding protein-3 (IGFBP-3) and its proteolytic fragments modulate IGF action, we used a fibroblast cell line to investigate the possibility of an interaction with the type 1 IGF receptor (IGFR-1).
