The long non-coding RNA BBOX1 antisense RNA 1 is upregulated in polycystic ovary syndrome (PCOS) and suppresses the role of microRNA-19b in the proliferation of ovarian granulose cells : Short title: BBOX1 antisense RNA 1 in cell proliferation. BMC Womens Health 2023; 23:508. [PMID: 37735639 PMCID: PMC10512487 DOI: 10.1186/s12905-023-02632-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 09/01/2023] [Indexed: 09/23/2023] Open
Abstract
BACKGROUND MicroRNA-19b (miR-19b) has been reported to be downregulated in polycystic ovary syndrome (PCOS), while its upstream regulators are unclear. We speculated that miR-19b could potentially form a binding relationship with BBOX1 antisense RNA 1 (BBOX1-AS1), a long non-coding RNA recognized for its critical role in ovarian cancer. Subsequently, we investigated into their interaction in PCOS. METHODS The expression of miR-19b and BBOX1-AS1 in follicular fluid from both control women (n = 80) and women with PCOS (n = 80) was detected by RT-qPCR. Correlations were analyzed with Pearson' correlation coefficient. The binding of miR-19b to the wild-type (-wt) ad mutant (-mut) BBOX1-AS1 was determined by RNA-RNA pulldown assay. Their interactions were detected by overexpression assay. Bromodeoxyuridine (BrdU) assay was applied for proliferation analysis. RESULTS BBOX1-AS1 was highly upregulated, while miR-19b was downregulated in PCOS. There was no close correlation across PCOS and the control samples. Consistently, they did not regulate the expression of each other in granulosa cells. However, BBOX1-AS1-wt, but not BBOX1-AS1-mut, could directly interact with miR-19b. BBOX1-AS1 suppressed the role of miR-19b in inhibiting granulosa cell proliferation. CONCLUSION BBOX1-AS1 is highly upregulated in PCOS, and it may serve as an endogenous competing RNA for miR-19b to suppress its role in inhibiting granulosa cell proliferation. Our study suggested the role of BBOX1-AS1 as a potential target to treat PCOS.

Optimal Treatment of 6-Dimethylaminopurine Enhances the In Vivo Development of Canine Embryos by Rapid Initiation of DNA Synthesis. Int J Mol Sci 2021; 22:ijms22147757. [PMID: 34299380 PMCID: PMC8303139 DOI: 10.3390/ijms22147757] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 07/16/2021] [Accepted: 07/17/2021] [Indexed: 02/06/2023] Open
Abstract
Artificial activation of oocytes is an important step for successful parthenogenesis and somatic cell nuclear transfer (SCNT). Here, we investigated the initiation of DNA synthesis and in vivo development of canine PA embryos and cloned embryos produced by treatment with 1.9 mM 6-dimethylaminopurine (6-DMAP) for different lengths of time. For experiments, oocytes for parthenogenesis and SCNT oocytes were cultured for 4 min in 10 μM calcium ionophore, and then divided into 2 groups: (1) culture for 2 h in 6-DMAP (DMAP-2h group); (2) culture for 4 h in DMAP (DMAP-4h group). DNA synthesis was clearly detected in all parthenogenetic (PA) embryos and cloned embryos incorporated BrdU 4 h after activation in DMAP-2h and DMAP-4h groups. In vivo development of canine parthenogenetic fetuses was observed after embryo transfer and the implantation rates of PA embryos in DMAP-2h were 34%, which was significantly higher than those in DMAP-4h (6.5%, p < 0.05). However, in SCNT, there was no significant difference in pregnancy rate (DMAP-2h: 41.6% vs. DMAP-4h: 33.3%) and implantation rates (DMAP-2h: 4.94% vs. DMAP-4h: 3.19%) between DMAP-2h and DMAP-4h. In conclusion, the use of DMAP-2h for canine oocyte activation may be ideal for the in vivo development of PA zygotes, but it was not more effective in in vivo development of canine reconstructed SCNT oocytes. The present study demonstrated that DMAP-2h treatment on activation of canine parthenogenesis and SCNT could effectively induce the onset of DNA synthesis during the first cell cycle.

Abstract
Patrinia scabiosifolia (PS) has bioactivities such as antitumor and anti-inflammation effects. However, its effects on human skin physiological activities, such as skin regeneration and wound healing, remain unclear. In this study, we investigated the effects of absolute extracted from PS flower (PSF) on migration and proliferation of human dermal keratinocyte (HaCat). The yield of PSF absolute obtained by solvent extraction method was 0.105 % and its five constituents were found in GC/MS analysis. The PSF absolute induced the proliferation and migration of HaCats. The absolute increased the phosphorylation of serine/threonine-specific protein kinase (Akt) and extracellular signal-regulated kinase1/2 (Erk1/2) in HaCats. In addition, the absolute stimulated the outgrowth of collagen sprouting of HaCats. These results demonstrated, for the first time, that PSF absolute may have positive effects on skin regeneration and/or wound healing by inducing migration and proliferation of dermal keratinocytes via the Akt/Erk1/2 pathway. Therefore, PSF absolute may be a useful natural material for skin regeneration and/or wound healing.

Nutrients 2019; 11:nu11040936.

Abstract
Methotrexate (MTX), a folic acid antagonist, is widely used in cancer treatment. However, treatment with MTX reduces hippocampal neurogenesis, leading to memory deficits. Hesperidin (Hsd) is a flavonoid glycoside that promotes anti-inflammation, acts as an antioxidant, and has neuroprotective properties. Consumption of Hsd enhances learning and memory. In the present study, we investigated the protective effects of Hsd against MTX-induced impairments of memory and neurogenesis; male Sprague Dawley rats were administered with a single dose of MTX (75 mg/kg) by intravenous (i.v.) injection on days 8 and 15 or Hsd (100 mg/kg) by oral gavage for 21 days. Memory was tested using novel object location (NOL) and novel object recognition (NOR) tasks. Immunofluorescence staining of Ki-67, bromodeoxyuridine (BrdU), and doublecortin (DCX) was performed to assess cell proliferation, survival, and immature neurons. The data showed that Hsd and MTX did not disable locomotor ability. The MTX animals exhibited memory deficits in both memory tests. There were significant decreases in the numbers of cell proliferation, survival, and immature neurons in the MTX animals. However, co-administration with MTX and Hsd alleviated memory loss and neurogenesis decline. These results revealed that Hsd could protect against MTX side effects in the animals in this study.

Abstract
Atherosclerosis involves the proliferation and migration of vascular smooth muscle cells (VSMCs). The migration of VSMCs from the media into the intima and their subsequent proliferation are important processes in neointima formation in atherosclerosis and restenosis after percutaneous coronary interventions. Acarbose, an alpha-glucosidase inhibitor, has been demonstrated to not affect serum levels of glucose and decrease the progression of intima-media thickening in rabbits fed with a high cholesterol diet (HCD). We previously showed that increased Ras protein levels enhanced the migration of TNF-α treated A7r5 cells. The aim of this study was to determine the inhibitory effects of acarbose on Ras expression in A7r5 cells. Acarbose also inhibited the phosphorylation of focal adhesion kinase (FAK) and Akt, activities of the matrix metalloproteinases (MMPs) MMP-2 and MMP-9, and protein expressions of small G proteins (Ras, Cdc42, RhoA, and Rac1) in a dose-dependent manner. We also found that acarbose could effectively inhibit the proliferation and migration of RasG12V A7r5 cells by blocking small G proteins and phosphoinositide-3-kinase (PI3K)/Akt signaling. These studies demonstrated that acarbose could theoretically decrease atherosclerosis by targeting Ras signaling.
