- Astrocyte-derived extracellular matrix (ECM) proteins are critical for synaptic development and glutamatergic signaling, yet their role in attention deficit hyperactivity disorder (ADHD) remains poorly understood. This study examined serum levels of Thrombospondin-1 (Tsp-1), Sparc, and Sparcl-1 in children with ADHD and explored their associations with behavioral symptoms, executive dysfunction, and social impairments. Eighty-six children aged 6-12 years participated: 46 medication-naive with ADHD and 40 age- and sex-matched neurotypical controls. Clinical measures included the Conners' Parent Rating Scale-Revised: Long Form (CPRS-R:L), Social Responsiveness Scale (SRS), and Behavior Rating Inventory of Executive Function (BRIEF). Serum levels of Tsp-1, Sparc, and Sparcl-1 were quantified via ELISA. Children with ADHD exhibited significantly lower serum levels of Tsp-1 (p < 0.001), Sparc (p = 0.020), and Sparcl-1 (p = 0.049) than controls. Lower Sparc levels were associated with poorer executive functioning and reduced social responsiveness, while lower Tsp-1 levels were positively associated with higher ADHD symptom severity. This study provides the first evidence of reduced serum astrocyte-derived ECM proteins in children with ADHD, implicating glia-mediated synaptic dysregulation in the disorder's pathophysiology. These findings suggest a novel glia-centered mechanism and support the potential of ECM proteins as biomarkers for ADHD subtypes and as targets for future therapeutic interventions. - Source: PubMed

Kısmet Nilüfer YıldızGökçearslan Selen SezenÜlkar Serenay ElgünAçıkel Sadettin Burak - Secreted protein acidic and rich in cysteine-like 1 (SPARCL-1) is an extracellular matrix-associated matricellular protein involved in endothelial stability and vascular homeostasis. Given the central role of endothelial dysfunction in preeclampsia, we hypothesized that circulating SPARCL-1 levels would differ between early- and late-onset preeclampsia. Accordingly, this study aimed to evaluate maternal serum SPARCL-1 levels in women with early- and late-onset preeclampsia and to assess its diagnostic performance by disease onset. - Source: PubMed

Shirinova SevinjÖzalp MiraçToplu Murat İbrahimAydoğdu Burak DenizMihmanlı Veli - The SPARC (secreted protein acidic and rich in cysteine) family represents a unique class of matricellular proteins - including SPARC, SPARCL1, SPOCK1-3, SMOC1-2, and FSTL1 - that regulate extracellular matrix (ECM) dynamics, cell signaling, and tissue homoeostasis. In cancer, their expression is frequently dysregulated, through epigenetic mechanisms, microRNAs, and interactions within the tumor microenvironment (TME). Dysregulation of SPARC family members is most pronounced in aggressive malignancies with SPARC, SPARCL1, SPOCK1, and SPOCK2 most consistently altered. These proteins drive tumor progression through ECM remodeling, epithelial-mesenchymal transition (EMT), maintenance of cancer stemness, immune modulation, and drug resistance acquisition. Their functions are highly context-dependent, exerting either tumor-suppressive or oncogenic effects depending on tissue types and disease stage. While their secreted nature positions family members as promising serum or plasma biomarkers, challenges such as ECM protein undruggability, functional heterogeneity, and the absence of upstream regulators have so far precluded direct therapeutic targeting, with no agents advancing to clinical trials. Nonetheless, indirect strategies leveraging their biology show preclinical promise. This review synthesizes current knowledge on SPARC family structure, regulation, and context-specific functions in cancer-TME interactions, emphasizing their dual roles as modulators of progression and resistance. By integrating mechanistic insights with translational advances, we highlight the emerging utility of SPARC family proteins in precision oncology and underscore the need for deeper understanding to enable effective biomarker development and targeted therapeutic strategies. - Source: PubMed
