Irisin is a myokine that modulates the benefits of exercise, which may include bone health. This study was planned to examine irisin\u2019s impact in preventing osteoporosis after ovariectomy. 4 groups of female albino rats (10 rats\/group): control, sham\u2010operated, ovariectomized (OVX\u2010control), and OVX\u2010irisin\u2010treated. Serum levels of bone markers [osteocalcin (OC), bone alkaline phosphatase (BALP), tartrate\u2010resistant acid phosphatase (TRAP), calcium (Ca<jats:sup>++<\/jats:sup>), phosphorus (P)], glucose, and insulin were being measured. Body mass index, Homeostatic Model Assessment of Insulin Resistance (HOMA\u2010IR), dry and ash femur weight, and bone contents of Ca<jats:sup>++<\/jats:sup> and P were investigated. The femur was examined histopathologically. The OVX\u2010control group showed an increase in serum levels of OC, BALP, TRAP, calcium, phosphorus, BMI, glucose, insulin, and HOMA\u2010IR (<jats:italic>P<\/jats:italic> &lt; 0.05) and a reduction in dry and ash weight of the femur, the concentration of calcium and phosphorus content in bone ash (<jats:italic>P<\/jats:italic> &lt; 0.05). The OVX\u2010irisin\u2010treated group exhibited a decrease in serum levels of OC, BALP and TRAP, calcium, phosphorus, BMI, glucose, insulin, HOMA\u2010IR (<jats:italic>P<\/jats:italic> &lt; 0.05), and a rise in dry and ash weight of the femur, the concentration of calcium and phosphorus in bone ash (<jats:italic>P<\/jats:italic> &lt; 0.05). Histological examination of the distal femur diaphysis of the OVX\u2010irisin\u2010treated group exhibited proper bone architecture and density compared with that of the OVX\u2010control group. It is concluded that irisin treatment in the OVX rats safeguarded the regular bone architecture and normal levels of serum bone biomarkers. Irisin may be a possible novel target in the prohibition of postmenopausal osteoporosis.<\/jats:p>","DOI":"10.1155\/2021\/5570229","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T17:33:05Z","timestamp":1619544785000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Irisin Has a Protective Role against Osteoporosis in Ovariectomized Rats"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5427-7126","authenticated-orcid":false,"given":"Enas N.","family":"Morgan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0923-7525","authenticated-orcid":false,"given":"Ashwag Saleh","family":"Alsharidah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5541-7928","authenticated-orcid":false,"given":"Ayman M.","family":"Mousa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4618-9083","authenticated-orcid":false,"given":"Husam M.","family":"Edrees","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,4,27]]},"reference":[{"key":"e_1_2_11_1_2","first-page":"95","article-title":"Influence of intensive exercise on insulin-like growth factor I, thyroid and steroid hormones in female gymnasts","volume":"1","author":"Jahreis G.","year":"1991","journal-title":"Growth Regulation"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S8756-3282(02)00835-9"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/srep08889"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.4161\/adip.26082"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/0004563218759371"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2015.10.026"},{"key":"e_1_2_11_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.beem.2014.07.003"},{"key":"e_1_2_11_8_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-017-1403-x"},{"key":"e_1_2_11_9_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0071665"},{"key":"e_1_2_11_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s001980070050"},{"key":"e_1_2_11_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00198-006-0172-4"},{"key":"e_1_2_11_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2006.12.002"},{"key":"e_1_2_11_13_2","doi-asserted-by":"publisher","DOI":"10.1359\/jbmr.2000.15.1.2"},{"key":"e_1_2_11_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsbmb.2013.09.008"},{"key":"e_1_2_11_15_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2004-0434"},{"key":"e_1_2_11_16_2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.163.4.427"},{"key":"e_1_2_11_17_2","doi-asserted-by":"publisher","DOI":"10.1042\/CS20160005"},{"key":"e_1_2_11_18_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature10777"},{"key":"e_1_2_11_19_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0060563"},{"key":"e_1_2_11_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmet.2015.08.001"},{"key":"e_1_2_11_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.peptides.2014.03.021"},{"key":"e_1_2_11_22_2","doi-asserted-by":"publisher","DOI":"10.1111\/dom.12268"},{"key":"e_1_2_11_23_2","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/7816806"},{"key":"e_1_2_11_24_2","doi-asserted-by":"publisher","DOI":"10.1111\/cen.12672"},{"key":"e_1_2_11_25_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1516622112"},{"key":"e_1_2_11_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdiacomp.2013.03.002"},{"key":"e_1_2_11_27_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2013-2373"},{"key":"e_1_2_11_28_2","doi-asserted-by":"publisher","DOI":"10.4067\/s0716-97602008000300002"},{"key":"e_1_2_11_29_2","first-page":"424","article-title":"The laboratory rat as an animal model for osteoporosis research","volume":"58","author":"Lelovas P.
