Background: SULF2 is an extracellular sulfatase that acts on heparan sulfate proteoglycans and modulates multiple signaling pathways. It is normally bound to the cell surface but can be released into the medium of cultured cells. SULF2 is known to be increased in cirrhotic liver compared to healthy liver. We asked whether SULF2 protein was present in the blood of healthy controls and increased in patients with liver cirrhosis.
Methods: We devised a sandwich ELISA for SULF2 using 2 novel monoclonal antibodies (mAbs) and measured its levels in sera of normal individuals and cirrhosis patients.
Results: SULF2 was higher in cirrhosis patients (1460 ± 1160 pg/ml, N=34) than in healthy individuals (728 ± 400 pg/ml, N=37). SULF2 levels increased with age in both healthy and patient groups.
Conclusions: SULF2 may be a useful serologic biomarker for liver cirrhosis.

Background: Glioma is a malignancy with challenging clinical treatment and poor prognosis. Platelets are closely associated with tumor growth, propagation, invasion, and angiogenesis. However, the role of platelet-related genes in glioma treatment and prognosis remains unclear.

Targeting the genes regulate the lineage commitment of human mesenchymal stem cells (hMSCs) to adipocytes provides a promising strategy for addressing obesity. In this study, we investigated the therapeutic potential of cell-penetrating anti-sense peptide nucleic acids (PNAs) designed to enhance solubility and hybridization properties, specifically targeting sulfatase 2 (SULF2), a potential reciprocal regulator of adipocyte and osteoblast differentiation in hMSCs. Cell-penetrating modified PNA oligomers effectively inhibit SULF2 gene transcription, leading to significant reductions in adiponectin protein synthesis and intracellular lipid droplet accumulation during adipogenesis in human bone marrow-derived MSCs (hBM-MSCs).

Article Synopsis
- The study investigates the role of heparan sulfate 6-O-endosulfatases (Sulf1 and Sulf2) in bone marrow hematopoiesis by using a new mouse model with specific deletion of these enzymes in myeloid cells.
- Male LysM-Sulf knockout mice showed an age-related increase in hematopoietic stem cells and granulocyte-monocyte lineages, but a decrease in lymphoid progenitors and B cells, while red blood cell and platelet production was impaired at later stages.
- The findings highlight age- and sex-dependent differences in hematopoiesis and 6-O-sulfation levels, suggesting that Sulfs play a crucial role in regulating blood cell development in mice.

Multiple sclerosis (MS) is the most common inflammatory neurodegenerative disease of the central nervous system (CNS) in young adults and results in progressive neurological defects. The relapsing-remitting phenotype (RRMS) is the most common disease course in MS, which ultimately progresses to secondary progressive MS (SPMS), while primary progressive MS (PPMS) is a type of MS that worsens gradually over time without remissions. There is a gap in knowledge regarding whether the relapsing form can be distinguished from the progressive course, or healthy subjects (HS) based on an altered serum metabolite profile.

Heparan sulfate (HS) proteoglycans are important regulators of cellular responses to soluble mediators such as chemokines, cytokines and growth factors. We profiled changes in expression of genes encoding HS core proteins, biosynthesis enzymes and modifiers during macrophage polarisation, and found that the most highly regulated gene was Sulf2, an extracellular HS 6-O-sulfatase that was markedly downregulated in response to pro-inflammatory stimuli. We then generated Sulf2 bone marrow chimeric mice and examined inflammatory responses in antigen-induced arthritis, as a model of rheumatoid arthritis.
