Morphine 0-8 telomerase reverse transcriptase Homo sapiens 94-98 34482039-4 2021 To investigate whether telomere length is affected by morphine or not, the expressions of hTERT and TERF2 in morphine treated human SH-SY5Y cells were determined and compared with untreated cells. Morphine 54-62 telomerase reverse transcriptase Homo sapiens 90-95 34482039-4 2021 To investigate whether telomere length is affected by morphine or not, the expressions of hTERT and TERF2 in morphine treated human SH-SY5Y cells were determined and compared with untreated cells. Morphine 109-117 telomerase reverse transcriptase Homo sapiens 90-95 34482039-8 2021 RESULTS: The hTERT and TERF2 mRNA levels were down regulated in morphine treated cells as a function of exposure duration. Morphine 64-72 telomerase reverse transcriptase Homo sapiens 13-18 34482039-11 2021 In the SH-SY5Y cells treated by 5 muM morphine for 60 consecutive days, the hTERT and TERF2 mRNA levels and relative telomere lengths remarkably decreased. Morphine 38-46 telomerase reverse transcriptase Homo sapiens 76-81 34482039-12 2021 CONCLUSIONS: Reversible alteration of mRNA levels by removing morphine from culture medium, and effect of NAC in co-treatment of morphine plus NAC, emphasize the role of reactive oxygen species in down-regulation of the expression of hTERT and TERF2 by morphine. Morphine 62-70 telomerase reverse transcriptase Homo sapiens 234-239 34482039-12 2021 CONCLUSIONS: Reversible alteration of mRNA levels by removing morphine from culture medium, and effect of NAC in co-treatment of morphine plus NAC, emphasize the role of reactive oxygen species in down-regulation of the expression of hTERT and TERF2 by morphine. Morphine 129-137 telomerase reverse transcriptase Homo sapiens 234-239 34482039-12 2021 CONCLUSIONS: Reversible alteration of mRNA levels by removing morphine from culture medium, and effect of NAC in co-treatment of morphine plus NAC, emphasize the role of reactive oxygen species in down-regulation of the expression of hTERT and TERF2 by morphine. Morphine 253-261 telomerase reverse transcriptase Homo sapiens 234-239 34482039-13 2021 Telomere attrition in morphine treated cells is a consequence of down-regulation of the expression of hTERT and TERF2. Morphine 22-30 telomerase reverse transcriptase Homo sapiens 102-107 35298792-10 2022 It also elevated the telomerase activity and restored the expressions of human telomerase reverse transcriptase (hTERT) and TERF2 in morphine-induced M17 neuronal cells. Morphine 133-141 telomerase reverse transcriptase Homo sapiens 113-118
