Article Title: Myrrh ameliorates endometriosis by enhancing ER stress-related apoptotic cell death
doi: 10.3892/etm.2026.13080
Figure Lengend Snippet: Myrrh reduces the growth of human endometriotic cells by activating apoptotic signaling pathways. Endometriotic cells (12Z) and normal endometrial cells (T-HESC) were treated with the indicated concentrations of myrrh. (A) Cell viability was analyzed by measuring at 450 nm wavelength using MTT after 24 h. (B) To assess apoptotic or dead cell populations, 12Z cells were treated with increasing doses of myrrh for 24 h, and the percentages of Annexin V-positive and PI-positive cells were measured (Annexin V: Ex 494/Em 525 nm; PI: Ex 535/Em 617 nm). After 24 h of treatment with each concentration of myrrh, mitochondria-associated apoptotic proteins were analyzed by immunoblotting. (C) Representatives immunoblot images of Bax and Bcl-2 are shown. (D) A major monomeric Bax band at ~21 kDa (monomer Bax) and higher-molecular-weight bands corresponding to oligomeric forms (tetramer Bax, ~84 kDa) are indicated. (E) Representative immunoblot images of caspase-3, caspase-9 and PARP are shown. GAPDH was used as an internal control. (F) Densitometric analysis of protein levels. Data are expressed as relative intensity compared to control. Data are expressed as mean ± standard error of the mean. Statistical analysis was performed using one-way ANOVA followed by Tukey's post hoc test. * P<0.05, ** P<0.01 and *** P<0.001. Ex, excitation; Em, emission; ; PARP, poly(ADP-ribose) polymerase.
