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.

Figure Lengend Snippet: Mechanism of action of myrrh in endometriosis. (A) 12Z were treated with the indicated concentrations of myrrh and TUDCA (200 µM). Cell viability was analyzed using MTT after 24 h, measured at a wavelength of 450 nm. (B) Schematic representation summarizing the experimental results and the potential mechanism by which myrrh exerts palliative effects on endometriosis. *** P<0.001.
