Abstract
OBJECTIVE Integrins are known as key molecules that importantly involve in fertilization. This study aimed to evaluate effects of vitrification on fertilization rate and expression of integrin genes, α9 and β1, on mice oocytes in GV and MІІ stages. MATERIALS AND METHODS From the ovarian tissue and fallopian tube of NMRI mice, germinal vesicle (GV, n = 200) and metaphase II (MII, n = 200) oocytes were obtained. Then, oocytes were distributed into 4 groups including non-vitrified GV, non-vitrified MII, vitrified GV, and vitrified MII. Cryotop method was used for vitrification and oocytes (for 4 weeks) were kept in liquid nitrogen. After that, by using an inverted microscope, the rate of survived oocytes was assessed. Also, in vitro fertilization (IVF) for oocytes, obtained from in vitro maturated MII and mice ovaries (ovulated MII), was done to assess embryos at differenced stages (2-cells, morula, and hatched). Finally, RT-qPCR was performed to investigate the mRNA expression of integrin genes (α9 and β1). RESULTS After vitrification, the rate of survived oocytes, 68.65%for GV and 65.07% % for MII, did not show a remarkable difference related to non-vitrified groups, while the fertilization rate in vitrified groups remarkably decrease compared to non-vitrified groups (p < 0.05). Also, the expression of α9 and β1 genes was significantly altered in vitrified groups when compared to non-vitrified groups (p < 0.05). There was no significant difference in embryo developmental rates for non-vitrified and vitrified groups. CONCLUSION Cryotop method for vitrification caused an alternation in oocyte quality by reducing fertilization rate and integrin gene expression.

Abstract
BACKGROUND Chlorogenic acid (CGA) is one of the well-known polyphenol compounds possessing several important biological and therapeutic functions. In order to optimize a culture system to achieve complete development of follicles, we focused on the effects of CGA supplementation during in vitro culture (IVC) on follicular development, oxidative stress, antioxidant capacity, developmental gene expression, and functional potential in cultured mouse ovarian tissue. METHODS AND RESULTS The collected whole murine ovaries were randomly divided into four groups: (1) non-cultured group (control 1) with 7-day-old mouse ovaries, (2) non-cultured group (control 2) with 14-day-old mouse ovaries, (3) cultured group (experimental 1) with the culture plates containing only the basic culture medium, (4) cultured group (experimental 2) with the culture plates containing basic culture medium + CGA (50, 100 and 200 µmol/L CGA). Afterward, histological evaluation, biochemical analyses, the expression assessment of genes related to follicular development and apoptosis as well as the analysis of 17-β-estradiol were performed. The results showed that supplementation of ovarian tissue with the basic culture media using CGA (100 µmol/l) significantly increased the survival, developmental and functional potential of follicles in whole mouse ovarian tissues after 7 days of culture. Furthermore, CGA (100 µmol/L) attenuated oxidative damage and enhanced the concentration of antioxidant capacity along with developmental gene expression. CONCLUSION It seems that supplementation of ovarian tissue with culture media using CGA could optimize follicular growth and development in the culture system.

Abstract
Objective: The aim of this study was to evaluate the effect of lysophosphatidic acid (LPA) supplementation during in vitro culture and transplantation of mouse ovaries on the follicular development and expression of vascular endothelial growth factor (VEGF) as an angiogenesis factor at the mRNA and protein levels. Materials and methods: Three weeks old mice ovaries were cultured in the presence and absence of LPA for 24 hours, then they were capsulated in sodium alginate in the presence and absence of LPA as four experimental groups. After transplantation the vaginal smears were performed daily to evaluate the initiation of the estrous cycle. The morphology and follicular distribution were analyzed at the first and fourth estrous cycles using hematoxylin and eosin staining. Then in the groups that showed higher and lower follicular development the immunohistochemistry assay was conducted to identify VEGF protein expression, and the real time RT-PCR was done to analyze the expression of Vegf gene at the first estrus cycle. Results: The large size follicles and also the corpus luteum were prominent in all transplanted groups at fourth estrus cycle in comparison with intact control groups. The statistically lowest percentage of small size follicles and the highest percentages of large size follicles were seen in LPA+/LPA- group (p<0.05). The expression ratio of Vegf to β-actin was significantly higher in this group in comparison with non-LPA treated and intact control groups (p <0.05). Conclusion: LPA as an angiogenesis factor increases the follicular development in transplanted ovaries but it causes early discharge of ovarian reserve.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect of lysophosphatidic acid (LPA) on the follicular development, incidence of cell death, and expressions of apoptosis related genes and miR-22 in transplanted ovaries. MATERIALS AND METHODS In this experimental study, three-week-old mice ovaries were cultured for 24 hours in the presence and absence of LPA, and we assessed cell survival and normal follicular rates in some of the cultured ovaries. The remaining cultured ovaries were autotransplanted in the presence and absence of LPA as four experimental groups (LPA-/LPA-, LPA-/LPA+, LPA+/LPA-, LPA+/LPA+). The follicular development, immunohistochemistry for BAX, and expressions of genes related to apoptosis and miR-22 by real time reverse transcription polymerase chain reaction (RTPCR) were studied at the first oestrous cycles in the recovered ovaries. Sera 17-β-oestradiol (E2) and progesterone (P4) levels were also assessed. RESULTS Both cell survival and normal follicular rates were significantly higher in cultured ovaries in the presence of LPA after 24 hours (P<0.05). There was an increase in follicular development in comparison with the intact control group in the four transplanted groups (P<0.05). The LPA+/LPA- group had significantly higher follicular development, a decline in BAX positive cells, and a decrease in pro-apoptotic gene expressions in parallel with enhanced expression of anti-apoptotic and miR-22 genes and higher levels of hormones compared with the non-treated and intact control groups (P<0.05). CONCLUSION LPA, as a survival factor, improves follicular development in transplanted ovaries by providing a balance between the anti- and pro-apoptotic genes in association with an increase in miR-22 expression.

Biochim Biophys Acta Mol Cell Biol Lipids 2020; 1866:158818.

Abstract
Hematopoiesis, the complex developmental process that forms blood components and replenishes the blood system, involves multiple intracellular and extracellular mechanisms. We previously demonstrated that lysophosphatidic acid (LPA), a lipid growth factor, has opposing regulatory effects on erythrocyte differentiation through activation of LPA receptors 2 and 3; yet the mechanisms underlying this process remain unclear. In this study, LPA2 is observed that highly expressed in common myeloid progenitors (CMP) in murine myeloid cells, whereas the expression of LPA3 displaces in megakaryocyte-erythroid progenitors (MEP) of later stage of myeloid differentiation. Therefore, we hypothesized that the switching expression of LPA2 and LPA3 determine the hematic homeostasis of mammalian megakaryocytic-erythroid lineage. In vitro colony-forming unit assays of murine progenitors reveal that LPA2 agonist GRI reduces the erythroblast differentiation potential of CMP. In contrast, LPA3 agonist OMPT increases the production of erythrocytes from megakaryocyte-erythrocyte progenitor cells (MEP). In addition, treatment with GRI reduces the erythroid, CMP, and MEP populations in mice, indicating that LPA2 predominantly inhibits myeloid differentiation at an early stage. In contrast, activation of LPA3 increases the production of terminally differentiated erythroid cells through activation of erythropoietic transcriptional factor. We also demonstrate that the LPA3 signaling is essential for restoration of phenylhydrazine (PHZ)-induced acute hemolytic anemia in mice and correlates to erythropoiesis impairment of Hutchinson-Gilford progeria Symptom (HGPS) premature aging expressed K562 model. Our results reveal the distinct roles of LPA2 and LPA3 at different stages of hematopoiesis in vivo, providing potentiated therapeutic strategies of anemia treatment.

Abstract
In vitro studies had shown that C-Phycocyanin (C-PC) inhibited cervical cancer HeLa cells growth. We constructed C-PC/CMC-CD55sp nanospheres using C-PC, Carboxymethyl Chitosan (CMC), and CD55 ligand peptide (CD55sp) to allow for targeted antitumor effects against HeLa cells in vitro and in vivo. The characteristics of the nanospheres were determined using FTIR, electron microscopy, and laser particle size analysis. Flow cytometry, laser confocal microscopy and small animal imaging system showed the targeting of C-PC/CMC-CD55sp nanospheres on HeLa cells. Subsequently, the proliferation and apoptosis were analyzed by Cell Counting Kit-8 (CCK-8), flow cytometry, TUNEL assay and electron microscopy. The expression of the apoptosis-related protein was determined using western blot. The stainings of Hematoxylin and Eosin (HE) were employed to evaluate the cell condition of tumor tissue sections. The cytokines in the blood in tumor-bearing nude mice was determined using ELISA. These results showed that C-PC/CMC-CD55sp nanospheres were successfully constructed and targeted HeLa cells. The constructed nanospheres were more effective than C-PC alone in inhibiting the proliferation and inducing apoptosis in HeLa cells. We also found that C-PC/CMC-CD55sp nanospheres had a significant inhibitory effect on the expression of antiapoptotic protein Bcl-2 and a promotion on the transformation of caspase 3 to cleaved caspase 3. C-PC/CMC-CD55sp nanospheres played an important role in tumor suppression, reduced the expression TGF-β, and increased IL-6 and TNF-α. This study demonstrates that the constructed new C-PC/CMC-CD55sp nanospheres exerted targeted antitumor effects in vivo and in vitro which provided a novel idea for application of C-PC, and provided experimental basis for comprehensive targeted treatment of tumors.

Supplementation of Culture Media with Lysophosphatidic Acid Improves The Follicular Development of Human Ovarian Tissue after Xenotransplantaion into The Back Muscle of γ-Irradiated Mice. CELL JOURNAL 2019; 22:358-366. [PMID: 31863662 PMCID: PMC6947004 DOI: 10.22074/cellj.2020.6752] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2019] [Accepted: 04/23/2019] [Indexed: 01/26/2023]
Abstract
Objective The aim of the present study was to evaluate the effects of lysophosphatidic acid (LPA) supplementation
of human ovarian tissue culture media on tissue survival, follicular development and expression of apoptotic genes
following xenotransplantation.
Materials and Methods In this experimental study, human ovarian tissue was collected from eight normal female
to male transsexual individuals and cut into small fragments. These fragments were vitrified-warmed and cultured
for 24 hours in the presence or absence of LPA, then xenografted into back muscles of γ-irradiated mice. Two weeks
post-transplantation the morphology of the recovered tissues were evaluated by hematoxylin and eosin staining. The
expression of genes related to apoptosis (BAX and BCL2) were analyzed by real time revers transcription polymerase
chain reaction (RT-PCR) and detection of BAX protein was done by immunohistochemical staining.
Results The percent of normal and growing follicles were significantly increased in both grafted groups in comparison to
the non-grafted groups, however, these rates were higher in the LPA-treated group than the non-treated group (P<0.05).
There was a higher expression of the anti-apoptotic gene, BCL2, but a lower expression of the pro-apoptotic gene, BAX,
and a significant lower BAX/ BCL2 ratio in the LPA-treated group in comparison with non-treated control group (P<0.05).
No immunostaining positive cells for BAX were observed in the follicles and oocytes in both transplanted ovarian groups.
Conclusion Supplementation of human ovarian tissue culture medium with LPA improves follicular survival and
development by promoting an anti-apoptotic balance in transcription of BCL2 and BAX genes.
