| abstractText | Niemann-Pick Type C1 (NPC1, MIM 257220) is a rare, progressive, lethal, inherited autosomal-recessive endolysosomal storage disease caused by mutations in the NPC1 leading to intracellular lipid storage. We analyzed mostly not jet known alterations of the weights of 14 different organs in the BALB/cNctr-Npc1(m1N)/-J Jackson Npc1 mice in female and male Npc1(+/+) and Npc1(-/-) mice under various treatment strategies. Mice were treated with (i) no therapy, (ii) vehicle injection, (iii) a combination of miglustat, allopregnanolone, and 2-hydroxypropyl-ss-cyclodextrin (HPssCD), (iv) miglustat, and (v) HPssCD alone starting at P7 and repeated weekly throughout life. The 12 respective male and female wild-type mice groups were evaluated in parallel. In total, 351 mice (176 Npc1(+/+), 175 Npc1(-/-)) were dissected at P65. In both sexes, the body weights of None and Sham Npc1(-/-) mice were lower than those of respective Npc1(+/+) mice. The influence of the Npc1 mutation and/or sex on the weights of various organs, however, differed considerably. In males, Npc1(+/+) and Npc1(-/-) mice had comparable absolute weights of lungs, spleen, and adrenal glands. In Npc1(-/-) mice, smaller weights of hearts, livers, kidneys, testes, vesicular, and scent glands were found. In female Npc1(-/-) mice, ovaries, and uteri were significantly smaller. In Npc1(-/-) mice, relative organ weights, i.e., normalized with body weights, were sex-specifically altered to different extents by the different therapies. The combination of miglustat, allopregnanolone, and the sterol chelator HPssCD partly normalized the weights of more organs than miglustat or HPssCD mono-therapies. |
