MMP1 and lobular neoplasia: Unfortunately, because of the inadequacy of laboratory data and clinical information in the older patients’ records, we were able to obtain laboratory data only from 36 patients (16 patients had eGFR > 60 mL/min, 16 patients had eGFR 30–59 mL/min, and four patients had eGFR <29 mL/min), which showed that the strong expression of MMP-1, MMP-2, and MMP-3 in the glomeruli of patients LN correlated with worse renal function (eGFR) at the time of kidney biopsy.
