“…However, in the absence of stimulation an increased concentration of inflammatory cytokines is considered negative as the cat is likely to experience a low level of inflammation, which is a risk factor for many diseases of aging such as arthritis, cystitis, and nephritis [19,20]. The reduced cytokine concentrations seen with the inclusion of dietary L-carnitine alone are similar to those that were reported in the human [21,22], rats [23], mice [24], and black seabream fish [25]. These data suggest that as in these other species, dietary CT food has a benefit in cats.…”

“…Many in vitro studies [22][23][24][25][26][27][28][29], and in vivo studies of animals [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] and humans [48][49][50][51][52][53][54][55][56][57][58][59] have reported different beneficial functions for carnitine. In the following, the main activities observed are reported.…”

“…A radiação UV-A justamente compromete os níveis adequados do PCNA, implicando em prejuízo ao reparo do DNA danificado pela própria radiação. Como há envolvimento de mecanismos de estresse oxidativo nesses eventos, agentes antioxidantes como a L-carnitina podem recuperar a expressão do PCNA na pele de animais que sofreram exposição à radiação UV-A (SALAMA et al, 2018). Foi observado que a riboflavina em altas doses é capaz de induzir intensa proliferação celular em cultura de células de câncer de pulmão, antagonicamente por mecanismos relacionados a maior síntese de citocinas associadas ao estresse oxidativo que induzem fatores de crescimento celular (YANG et al, 2013 De acordo com os dados expostos no presente estudo, observou-se que a riboflavina reestabeleceu a arquitetura usual da pele, remodelou e recuperou os depósitos de colágeno, induziu a expressão da capacidade proliferativa das células e aumentou a expressão de fator de crescimento endotelial vascular.…”

“…Estudos anteriores revelam que o estímulo na produção do TNF-α pode ser revertida com o uso de fatores antioxidantes (SALAMA et al, 2018). Os dados atuais revelaram que os animais expostos ao UV-A apresentaram aumento na expressão proteica do TNFR, mas o tratamento com riboflavina por via oral foi capaz de inibir esse processo.…”
