Effect of berberine combined with metformin on autophagy in polycystic ovary syndrome by regulating AMPK/AKT/mTOR pathway.

The pathologic mechanism of polycystic ovary syndrome (PCOS) is related to increased autophagy of granulosa cells. Both berberine and metformin have been shown to improve PCOS, but whether the combination of berberine and metformin can better improve PCOS by inhibiting autophagy remains unclear. PCOS models were constructed by injecting dehydroepiandrosterone into rats, and berberine, metformin or berberine combined with metformin was administered to rats after modeling.

CPEB1 induces autophagy and promotes apoptosis in ovarian granulosa cells of polycystic ovary syndrome.

Inflammatory damage in ovarian granulosa cells (GCs) is a key mechanism in polycystic ovary syndrome (PCOS), cytoplasmic polyadenylation element binding protein-1 (CPEB1) is important in inflammatory regulation, however, its role in PCOS is unclear. We aim to research the mechanism of CPEB1 in ovarian GCs in PCOS using dehydroepiandrosterone (DHEA)-induced PCOS rat models and testosterone-incubated GC models. The pathophysiology in PCOS rats was analyzed.

LncRNA SNHG12 promotes cell proliferation and inhibits apoptosis of granulosa cells in polycystic ovarian syndrome by sponging miR-129 and miR-125b.

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disease in women of childbearing age which is often associated with abnormal proliferation or apoptosis of granulosa cells (GCs). Studies proved that long non-coding RNA SNHG12 (lncRNA SNHG12) is significantly increased in ovarian cancer and cervical cancer patients and cells. The inhibition of lncRNA SNHG12 restrains the proliferation, migration, and invasion in tumor cells.

LIPUS combined with TFSC alleviates premature ovarian failure by promoting autophagy and inhibiting apoptosis.

Objective: Premature ovarian failure (POF), also known as primary ovarian insufficiency, is a major cause of infertility in female worldwide. Excessive apoptosis and impaired autophagy in ovarian granulosa cells are the main pathological mechanisms of POF. The total flavonoids from (TFSC) are often used in the treatment of gynecological endocrine disorders.

The ameliorating effects of Guizhi Fuling Wan combined with rosiglitazone in a rat ovarian model of polycystic ovary syndrome by the PI3K/AKT/NF-κB and Nrf2/HO-1 pathways.

Objective: GuizhiFulingWan (GFW) has been reported to be effective against polycystic ovary syndrome (PCOS) by possessing oxidative stress and inflammation which related to PI3K/AKT/NF-κB, Nrf2/HO-1 pathway. This study aims to probe the effects and mechanisms of GFW combined with rosiglitazone on PCOS PI3K/AKT/NF-κB and Nrf2/HO-1 pathways.

Methods: A rat PCOS model established by dehydroepiandrosterone (DHEA) injection.

MicroRNA-646 inhibits the proliferation of ovarian granulosa cells via insulin-like growth factor 1 (IGF-1) in polycystic ovarian syndrome (PCOS).

Introduction: Polycystic ovarian syndrome (PCOS) is a common endocrinopathy in women. MicroRNAs (miRNAs) have been proven to play a crucial role in balancing the proliferation and apoptosis of granulosa cells (GCs) in PCOS.

Material And Methods: The miRNA of PCOS was screened by bioinformatics analysis, and microRNA 646 (miR-646) was found to be involved in insulin-related pathways by enrichment analysis.

The effect of sitagliptin combined with rosiglitazone on autophagy and inflammation in polycystic ovary syndrome by regulating PI3K/AKT/mTOR and TLR4/NF-κB pathway.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder. Sitagliptin (Sit) and rosiglitazone (Ros) are widely used to treat PCOS, but the mechanism is unclear. This study explored the mechanism that Sit and Ros inhibited autophagy and inflammation in PCOS.

CircRNA circ_0043533 facilitates cell growth in polycystic ovary syndrome by targeting miR-1179.

Increasing evidence indicates that circular RNAs (CircRNAs) have an important role in human diseases, including polycystic ovary syndrome (PCOS). Recently, circ_0043533, a novel circRNA, was proposed to be involved in the progression of PCOS. However, its role in PCOS has not been explored.

Manufacturing NKG2D CAR-T cells with piggyBac transposon vectors and K562 artificial antigen-presenting cells.

Non-viral platforms can be applied rapidly and cost-effectively for chimeric antigen receptor (CAR)-T cell manufacturing. In the present paper, we describe in detail a clinically relevant manufacturing process for NKG2D CAR-T cells through electroporation of CAR-encoding piggyBac transposon plasmids and expansion with K562 artificial antigen-presenting cells. With an optimized protocol, we generated the final cell therapy products with 89.

miR-587 promotes cervical cancer by repressing interferon regulatory factor 6.

Background: Interferon regulatory factor 6 (IRF6) exhibits tumor-suppressive functions in several cancer types. In the present study, the antitumor properties and related pathway mechanism of IRF6 were investigated in cervical cancer.

Methods: Forty-one pairs of cervical cancer specimens and para-carcinoma tissues were collected to evaluate IRF6 expression using immunohistochemical staining and miR-587.

Clinical evaluation of improved MyoSure hysteroscopic tissue removal system for the resection of type II submucosal myomas.

This study aims to determine whether clinical evaluation of improved MyoSure hysteroscopic tissue removal system can remove type II submucosal myomas with safety and high success rate of the first operation.Fifty-three patients with type II submucosal myomas hospitalized in the Huzhou Maternity and Child Care Hospital were enrolled in this study. The submucosal myomas were with the diameter of >2 cm and ≤5 cm.

Associations of Promoter Methylations and mRNA Expressions of MMP-2, MMP-7 and MMP-9 with Primary Fallopian Tube Carcinoma.

Objective: To explore the associations of matrix metalloprotease-2 (MMP-2), MMP-7 and MMP-9 methylations and messenger ribonucleic acid (mRNA) expressions with primary fallopian tube carcinoma (PFTC) development and prognosis.

Methods: We recruited 48 patients with PFTC into the case group and 48 healthy individuals into the control group; PFTC tissues and normal fallopian tube tissues were obtained from subjects in both groups. Methylation specific polymerase chain reaction (PCR), reverse transcription PCR and the immunohistochemical method were used to examine methylation, mRNA expressions and protein expressions of MMP-2, MMP-7 and MMP-9, respectively.
