Low back pain (LBP) is the symptom of a group of syndromes with heterogeneous underlying mechanisms and molecular pathologies, making treatment selection and patient prognosis very challenging. Moreover, symptoms and prognosis of LBP are influenced by age, gender, occupation, habits, and psychological factors. LBP may be characterized by an underlying inflammatory process. Previous studies indicated a connection between inflammatory response and total plasma N-glycosylation. We wanted to identify potential changes in total plasma N-glycosylation pattern connected with chronic low back pain (CLBP), which could give an insight into the pathogenic mechanisms of the disease. ⋯ To our knowledge, this is a first large clinical study on CLBP patients and plasma N-glycome providing a new glycomics perspective on potential disease pathology.

Glycosylation is highly susceptible to changes of the physiological conditions, and accordingly, is a potential biomarker associated with several diseases and/or longevity. Semi-supercentenarians (SSCs; older than 105 years) are thought to be a model of human longevity. Thus, we performed glycoproteomics using plasma samples of SSCs, and identified proteins and conjugated N-glycans that are characteristic of extreme human longevity. ⋯ We found abundant glycans in SSCs, which may be associated with human longevity.

Mitochondrial biogenesis is crucial for the maintenance of mitochondrial function and cellular homeostasis. C1q/tumor necrosis factor-related protein-3 (CTRP3) is an adipokine that owns multiple functions on metabolic and cardiovascular diseases. However, whether CTRP3 affects mitochondrial biogenesis in cardiomyocytes remains unknown. ⋯ CTRP3 is an endogenous modulator for mitochondrial biogenesis, and may protect cardiomyocytes by ameliorating mitochondrial dysfunction.
