Insulin-like growth factors binding protein-6 (IGFBP-6) is involved in a relevant number of cellular activities and represents an important factor in the immune response, particularly in human dendritic cells (DCs). Over the past several years, significant insights into the IGF-independent effects of IGFBP-6 were discovered, such as the induction of chemotaxis, capacity to increase oxidative burst and neutrophils degranulation, ability to induce metabolic changes in DCs, and, more recently, the regulation of the Sonic Hedgehog (SHH) signaling pathway during fibrosis. IGFBP-6 has been implicated in different human diseases, and it plays a rather controversial role in the biology of tumors. Notably, well established relationships between immunity, stroma activity, and fibrosis are prognostic and predictive of response to cancer immunotherapy. This review aims at describing the current understanding of mechanisms that link IGFBP-6 and fibrosis development and at highlighting the multiple roles of IGFBP-6 to provide an insight into evolutionarily conserved mechanisms that can be relevant for inflammation, tumor immunity, and immunological diseases.

Breast cancer is one of the most diagnosed cancers worldwide. The insulin-like growth factor (IGF) system promotes proliferation and survival in breast cancer cells and is regulated by 6 insulin-like growth factor binding proteins (IGFBPs). The IGFBPs sequester IGFs to prolong their half-life and attenuate binding to insulin-like growth factor 1 receptor (IGF1R).

Cytokines constitute a family of proteins that modulate the immune system and are secreted by many cells. CXCL12, along with its receptor CXCR4, are essential players in numerous processes. Dysregulation of their function underlie the mechanism(s) of several pathologies, including malignancies.

Article Synopsis
  • This study investigates the genetic differences between postburn keloids and hypertrophic scars using single-cell sequencing to identify molecular biomarkers for accurate diagnosis.
  • Researchers conducted analyses on clinical samples to find genes that could distinguish between the two types of scars, focusing on fibroblast cells.
  • They identified two key genes, insulin-like growth factor binding protein 6 and tumor necrosis factor alpha-induced protein 6, which showed high diagnostic accuracy for differentiating keloids from hypertrophic scars.

Article Synopsis
  • Researchers are investigating potential biomarker signatures in serum and cerebrospinal fluid to better diagnose and categorize different types of migraines (episodic and chronic) since there are currently no known biomarkers for migraine.
  • The study identified key proteins that distinguish migraine patients from healthy controls, with a classification model achieving high sensitivity and specificity for diagnosing migraines.
  • Findings show that certain proteins, like ZFP-814 and CACNA1F, are linked to migraine persistence and may serve as indicators for treatment responses in migraine patients.

Prognostic Value of IGFBP6 in Breast Cancer: Focus on Glucometabolism.

Article Synopsis
  • IGFBP6 inhibits insulin-like growth factor II (IGF-II) and has potential as a tumor suppressor in breast cancer (BC), particularly in tumors overexpressing IGF-II.
  • A study using the TCGA database revealed that higher levels of IGFBP6 are linked to better overall survival in breast cancer patients, especially those with estrogen and progesterone receptor positivity.
  • IGFBP6's expression correlates negatively with glucose metabolism-related genes and is impacted by diabetes; it also enhances drug sensitivity to treatments like docetaxel and gemcitabine, suggesting a multifaceted role in BC prognosis and metabolism.
