Abstract
Aim: The influence of variants in pharmacokinetics-related genes on long-term exposure to tacrolimus (TAC)-based therapy and clinical outcomes was investigated. Patients & methods: Brazilian kidney recipients were treated with TAC combined with everolimus (n = 178) or mycophenolate sodium (n = 97). The variants in CYP2C8, CYP2J2, CYP3A4, CYP3A5, POR, ABCB1, ABCC2, ABCG2, SLCO1B1 and SLCO2B1 were analyzed. Main results: CYP3A5*3/*3 genotype influenced increase in TAC concentration from week 1 to month 6 post-transplantation (p < 0.05). The living donor and CYP2C8*3 variant were associated with reduced risk for delayed graft function (OR = 0.07; 95% CI = 0.03-0.18 and OR = 0.45; 95% CI = 0.20-0.99, respectively, p < 0.05). Conclusion: The CYP3A5*3 variant is associated with increased early exposure to TAC. Living donor and CYP2C8*3 variant seem to be protective factors for delayed graft function in kidney recipients.

Osteopontin deficiency ameliorates Alport pathology by preventing tubular metabolic deficits. JCI Insight 2018; 3:94818.

Abstract
Alport syndrome is a rare hereditary renal disorder with no etiologic therapy. We found that osteopontin (OPN) is highly expressed in the renal tubules of the Alport mouse and plays a causative pathological role. OPN genetic deletion ameliorated albuminuria, hypertension, tubulointerstitial proliferation, renal apoptosis, and hearing and visual deficits in the Alport mouse. In Alport renal tubules we found extensive cholesterol accumulation and increased protein expression of dynamin-3 (DNM3) and LDL receptor (LDLR) in addition to dysmorphic mitochondria with defective bioenergetics. Increased pathological cholesterol influx was confirmed by a remarkably increased uptake of injected DiI-LDL cholesterol by Alport renal tubules, and by the improved lifespan of the Alport mice when crossed with the Ldlr-/- mice with defective cholesterol influx. Moreover, OPN-deficient Alport mice demonstrated significant reduction of DNM3 and LDLR expression. In human renal epithelial cells, overexpressing DNM3 resulted in elevated LDLR protein expression and defective mitochondrial respiration. Our results suggest a potentially new pathway in Alport pathology where tubular OPN causes DNM3- and LDLR-mediated enhanced cholesterol influx and impaired mitochondrial respiration.

Cell Biochem Funct 2015; 33:503-8. [PMID: 26449633 DOI: 10.1002/cbf.3149] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2015] [Revised: 09/15/2015] [Accepted: 09/16/2015] [Indexed: 02/06/2023]
Abstract
The aim of this study was to elucidate functional and molecular effects of mycophenolic acid (MPA) on non-lymphatic, kidney epithelial cells treated with transforming growth factor (TGF). MPA effects were studied using HK2 cells incubated with EGF and TGF. The reversibility of these effects was verified using guanosine and 8-aminoguanosine. The following assays were applied: cell proliferation, viability, collagen matrix contraction, scratch wound closure, spindle index, FACS with anti-CD29 and anti-CD326, promoter demethylation of RAS protein activator like 1 (RASAL1), as well as gene expression of RASAL1, integrin 1ß (ITGB1) (CD29) and epithelial cell adhesion molecule (EpCam) (CD326). Cell proliferation was inhibited by increasing concentrations of MPA, whereas neither apoptosis nor cytotoxicity was detected. Stimulation with EGF and/or TGF led to a significant collagen matrix contraction that was successfully inhibited by MPA. In addition, scratch wound closure was inhibited by incubation with TGF alone or with EGF. Under the same conditions, cell morphology (spindle shape) and molecular phenotype (ITGB1(High)EpCam(Low)/ITGB1(Low)EpCam(High)) were both significantly changed, suggesting an epithelial to mesenchymal transformation. Cell morphology and motility, as well as molecular phenotype, were reversible after MPA treatment with TGF transformation in both presence/absence of EGF, thereby suggesting a correlation with the previously described antifibrotic effects of MPA. Dysregulation of TGF signal transduction appears to be related to progression of fibrosis. A TGF-transformed kidney epithelial cell line derived from human proximal tubules was used to study whether the immunosuppressive drug: MPA possesses any functional or molecular antifibrotic effects. Functional and morphological in vitro changes induced by both the TGF and epithelial-growth-factor were reversible by treatment with MPA. An inhibitory effect of MPA on the TGF pathway appears to be responsible for the previously described antifibrotic effects of the MPA in the COL4A3-deficient mouse model of renal fibrosis.
