    ..In addition, in the db/db Nx mice, 4-6 mo after Nx, there was an exacerbation of the lesions of diabetic nephropathy, as quantified by a significant increase in the ratio of mesangial surface area to total glomerular surface area. ..
  2. Balabanian S, Gendron N, MacKenzie A. Histologic and transcriptional assessment of a mild SMA model. Neurol Res. 2007;29:413-24 pubmed
    ..Furthermore, changes occur, which may be reactive to and not causative of the cellular loss, involving central cellular functions as well as calcium modulating proteins. ..
  3. Berube N, Jagla M, Smeenk C, De Repentigny Y, Kothary R, Picketts D. Neurodevelopmental defects resulting from ATRX overexpression in transgenic mice. Hum Mol Genet. 2002;11:253-61 pubmed
    ..Our findings indicate that ATRX dosage is crucial for normal development and organization of the cortex, and emphasize the relevance of our model for the study of ATRX function and disease pathogenesis. ..

    ..In contrast, ANG-(1-7) does not affect albuminuria after (5/6) Nx. We propose that endogenous ACE2 is renoprotective in CKD. ..

    ..However, the depletion of profilin II and the restoration of plastin 3 are not sufficient to rescue the SMA phenotype. Our study suggests that additional regulators of actin dynamics must also contribute to SMA pathogenesis. ..
  8. Albert P, Lemonde S. 5-HT1A receptors, gene repression, and depression: guilt by association. Neuroscientist. 2004;10:575-93 pubmed
    ..The authors review evidence that altered transcription of the 5-HT1A receptor can affect the serotonin system and limbic and cortical areas, leading to predisposition to depression. ..
