Thrombospondin-1 (TSP1) plays an indirect role in collagen homeostasis through interactions with matrix metalloproteinases and transforming growth factor-beta1 (TGF-beta1); TSP1 also affects collagen fibril formation directly.
Thbs1 is a critical component of mechanotransduction, as well as a modulator of elastic fiber organization. Maladaptive upregulation of Thbs1 results in disruption of elastin-contractile units and dysregulation of actin cytoskeletal remodeling, contributing to the development of ascending aortic aneurysms.
The analysis of a large transcriptomic dataset derived from the tumors of patients with Triple Negative Breast Cancer revealed that the expression of CD163, CXCR4, THBS1 predicted relapse-free survival.
Together with previous evidence implicating LTBP4, the THBS1 modifier locus regulates variants in gene interaction networks in mitigating disease progression in muscular dystrophy.
This study revealed the opposite clinical relevance of TSP-1 and its autoantibody in SLE for the first time. TSP-1 may play an anti-inflammatory and immunoregulatory role in SLE autoimmunity. Its autoantibody was increased more frequently in disease-active patients and was associated with more severe clinical manifestations, which implicated its antagonistic role on TSP-1 and its involvement in the pathogenesis of SLE.

HtrA1 cleavage of thrombospondin-1 generates a proangiogenic fragment in the polarized retinal pigment epithelial cell model of age-related macular degeneration.
Following Schistosoma exposure, TSP-1 levels in the lung increase, via recruitment of circulating monocytes, while TSP-1 inhibition or knockout bone marrow prevents TGF-beta activation and protects against pulmonary hypertension development.
High THBS1 expression is associated with migration, invasion, and progression of bladder cancer.
intracellular dynamics of the TSP1-induced apoptosis signaling pathway
TSP-1 effectively elevated P. gingivalis LPS-induced inflammation mediated by the NF-kappaB pathway and may be critical for pathology of periodontitis.
These findings indicate that PRR13/THBS1 and TXN expression could be used for the prediction of resistance to treatment of epithelial ovarian cancer patients.
We observed an upregulation in the expression of TSP1 and TSP2 mRNA in control mouse cochleae following noise exposure. afferent synaptic counts and auditory brainstem responses (ABRs) in noise-exposed TSP1 and TSP2 knockout (-/-) mice exhibited a worst recovery than controls. TSP1-/- mice showed greater susceptibility to noise-induced hearing loss at low frequencies.
Study in mouse pneumonia model shows that thrombospondin-1 (TSP-1) dose-dependently inhibits Pseudomonas aeruginosa (PA) metalloendoprotease LasB, a virulence factor. TSP-1-deficient mice show reduced survival, impaired host defense, and increased lung permeability with exaggerated neutrophil activation following acute intrapulmonary PA infection.
In intrinsically photosensitive retinal ganglion cells (ipRGCs), Thbs1 was the most differentially expressed gene during axon regeneration and cell survival.THBS1 knockdown in RGCs eliminated axon regeneration. RGC overexpression of THBS1 enhanced regeneration in both ipRGCs and non-ipRGCs. The trimerization and C-terminal domains promoted regeneration, while the THBS type-1 repeats were dispensable.
neither adipocyte nor myeloid/macrophage-specific deletion of TSP1 affected the development of high-fat diet-induced obesity. Adipocyte-specific deletion of TSP1 did not protect mice from obesity-induced inflammation and IR. Obese mice with myeloid/macrophage loss of TSP1 had reduced macrophage accumulation in fat, which was accompanied with reduced inflammation, improved glucose tolerance and insulin sensitivity.
TSP-1 appears to play an accessory role in modulating Mp activity in humans and BlaJ mice in a gender, age and muscle-dependent manner, but is unlikely a primary driver of disease progression of dysferlinopathy.
TSP-1 may be beneficial for maintaining BBB integrity in the early phase and functional recovery in late phase after traumatic brain injury.
In a laser injury-induced thrombosis model, P-selectin modulates thrombus propagation independently of VWF and TSP1
These findings shed light on the mechanisms leading to beta-cell failure during metabolic stress and point to THBS1 as an interesting therapeutic target to prevent oxidative stress in type 2 diabetes.
cultured astrocytes isolated from an Fmr1 knockout (Fmr1 KO) mouse model of Fragile X syndrome displayed a significant decrease in TSP-1 protein expression compared to the wildtype (WT) astrocytes.
In pulmonary hypertension TSP1-CD47 is upregulated, and contributes to pulmonary arterial vasculopathy and dysfunction.
HIF-1alpha induced angiogenesis by upregulating not only vascular endothelial growth factor but also miR-21 via inhibiting a novel target gene TSP-1. Both of them may contribute to the protective effect of HIF-1alpha on renal I/R injury.
the results obtained by combining bioinformatics and preclinical studies strongly suggest that targeting TSP-1/CD47 axis may represent a valuable therapeutic alternative for hampering melanoma spreading.

Increased TSP-1 expression in non-heart-beating donors may indicate a compensatory response to the reported diminished TGF-beta1 expression.
ELL (Eleven-Nineteen Lysine-rich Leukemia) acts as a transcription factor for direct thrombospondin-1 regulation
The protein encoded by this gene is a subunit of a disulfide-linked homotrimeric protein. This protein is an adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. This protein can bind to fibrinogen, fibronectin, laminin, type V collagen and integrins alpha-V/beta-1. This protein has been shown to play roles in platelet aggregation, angiogenesis, and tumorigenesis.
