The objective of our in vitro study was to quantify the biochemical profile where the total polyphenol, flavonoid and phenolic acid content was determined. The antioxidant potential of microgreen extract from Trigonella foenum-graecum L., was measured molybdenum reducing power assay. Specifically, the study assessed parameters such as metabolic activity (AlamarBlueTM assay), membrane integrity (CFDA-AM assay), mitochondrial potential (JC-1 assay), as well as reactive oxygen species generation (NBT assay). In addition, the steroid hormone release in TM3 murine Leydig cells after 12 h and 24 h exposures were quantified by enzyme-linked immunosorbent assay. The gained results indicate the highest value in total flavonoid content (182.59+/-2.13 mg QE) determination, supported by a significant (108.25+/-1.27 mg TE) antioxidant activity. The effects on metabolic activity, cell membrane integrity, and mitochondrial membrane potential were found to be both time- and dose-dependent. Notably, a significant suppression in reactive oxygen species generation was confirmed at 150, 200 and 250 microg/ml after 24 h exposure. In addition, progesterone and testosterone release was stimulated up to 250 microg/ml dose of Trigonella, followed by a decline in both steroid production at 300 and 1000 microg/ml. Our results indicate, that Trigonella at lower experimental doses (up to 250 microg/ml) may positively affect majority of monitored cell parameters in TM3 Leydig cells. Overleaf, increasing experimental doses may negatively affect the intracellular parameters already after 12 h of in vitro exposure. Key words Microgreens, Trigonella foenum-graecum L., Fenugreek, Leydig cells, Male reproduction.

The aim of the study was to examine the potential impacts of bisphenol A (BPA) and its analogues BPB, BPF, and BPS on mice TM3 Leydig cells, with respect to basal cell viability parameters such as metabolic activity, cell membrane integrity, and lysosomal activity after 48-h exposure. In addition, monitoring of potential bisphenol ́s actions included evaluation of ROS production and gap junctional intercellular communication (GJIC) complemented by determination of testosterone secretion. Obtained results revealed significant inhibition in mitochondrial activity started at 10 microg/ml of bisphenols after 48-h exposure. Cell membrane integrity was significantly decreased at 5 microg/ml of BPA and BPF and 10, 25, and 50 microg/ml of BPA and BPS. The lysosomal activity was significantly affected at 10, 25, and 50 microg/ml of applied bisphenols. A significant overproduction of ROS was recorded mainly at 5 and 10 microg/ml of tested compounds. In addition, significant inhibition of GJIC was observed at 5 microg/ml of BPB followed by a progressive decline at higher applied doses. In the case of testosterone production, a significant decline was confirmed at 10, 25 and 50 microg/ml.

Several plants have the potential to protect essential reproductive processes such as spermatogenesis or steroidogenesis, however, effective concentrations and main mechanisms of action are still unknown. This in vitro study was aimed to assess the effects of Apium graveolens L., Levisticum officinale, and Calendula officinalis L. extracts on the structural integrity, functional activity and gap junctional intercellular communication (GJIC) in mice Leydig cells. TM3 cells were grown in the presence of experimental extracts (37.5; 75; 150 and 300 μg/ml) for 24 h. For the present study, high-performance liquid chromatography analysis was used to quantify flavonoids or phenolic acids. Subsequently, Leydig cell viability was assessed by alamarBlue assay, while the cell membrane integrity was detected by 5-carboxyfluorescein diacetate-acetoxymethyl ester. The level of steroid hormones production was determined by enzyme-linked immunosorbent assay. Additionally, GJIC was assessed by scalpel loading/dye transfer assay. According to our results, Apium graveolens L. significantly increased the viability and cell membrane integrity at 75 μg/ml (109.0±4.3%) followed by a decline at 300 μg/ml (89.4±2.3%). In case of Levisticum officinale and Calendula officinalis L. was observed significant decrease at 150 μg/ml (88.8±11.66%; 87.4±6.0%) and 300 μg/ml (86.2±9.3%; 84.1±4.6%). Furthermore, Apium graveolens L. significantly increased the progesterone and testosterone production (75 and 150 μg/ml) however, Levisticum officinale and Calendula officinalis L. significantly reduced steroid hormones synthesis at 150 and 300 μg/ml. Finally, the disturbance of GJIC was significantly affected at 300 μg/ml of Levisticum officinale (82.5±7.7%) and Calendula officinalis L. (79.8±7.0%). The balanced concentration ratio may support the Leydig cell function, steroidogenesis as well as all essential parameters that may significantly improve reproductive functions.

The aim of our study was to reveal the in vitro effects of Salvia officinalis L. (37.5, 75, 150, 200, 250, 300 and 600 µg/ml) extract on the TM3 Leydig cell viability, membrane integrity, steroidogenesis and reactive oxygen species production after 24 h and 48 h cultivation. For the present study, the extract prepared from Salvia officinalis L. leaves was analysed by high performance liquid chromatography (HPLC) for selected flavonoids and phenolic acids followed by a determination of its free radicals scavenging activity (DPPH). Furthermore, Leydig cell viability was assessed by the mitochondrial toxicity assay (MTT), while the membrane integrity was evaluated by 5- carboxyfluorescein diacetate-acetoxymethyl ester (5-CFDA-AM). The level of steroid hormones was performed by enzyme-linked immunosorbent assay (ELISA) from the culture media, while the superoxide radical generation was measured by the nitroblue tetrazolium chloride (NBT) assay. The results show that experimental concentrations did not damage the cell membrane integrity and viability when present at below 300 µg/ml, it was only at 600 µg/ml that a significant (P<0.05) cell viability decline was observed after a 48 h cultivation. A significant (P<0.05) stimulation of testosterone secretion was recorded at 250 µg/ml for 24 h, while the prolonged cultivation time significantly (P<0.05) increased the testosterone and progesterone production at 150, 200, 250 and 300 µg/ml. Furthermore, none of the selected doses exhibited significant ROS-promoting effects however, the highest dose of Salvia initiated the free radical scavenging activity in cultured mice Leydig cells.

The increasing worldwide production of bisphenols has been associated to several human diseases, such as chronic respiratory and kidney diseases, diabetes, breast cancer, prostate cancer, behavioral troubles and reproductive disorders in both sexes. The aim of the present in vitro study was to evaluate the potential impact bisphenols A, B, S and F on the cell viability and testosterone release in TM3 Leydig cell line. Mice Leydig cells were cultured in the presence of different concentrations of bisphenols (0.04-50 µg.ml-1) during 24 h exposure. Quantification of the cell viability was assessed using the metabolic activity assay, while the level of testosterone in cell culture media was determined by enzyme-linked immunosorbent assay. Within the panel of substances under investigations, the higher experimental concentrations (10; 25 and 50 µg.ml-1) significantly (P<0.001) decreased Leydig cells viability, while the same doses of BPA and BPB also reduced testosterone production significantly (P<0.001). Taken together, the results of our study reported herein is a consistent whit the conclusion that higher experimental doses of bisphenols have a cytotoxic effect and could have a dose-dependent impact on testosterone production.
