IGF2BP3 is upregulated in endometrial cancer and tightly regulates the growth of drug-resistant endometrial cancer cells via HMGA1

Objective: Endometrial cancer (EC) is a malignant tumor with various histological subtypes and molecular phenotypes. The evaluation of drug resistance is important for cancer treatment. Progesterone resistance is the major challenge in EC. Knowledge of drug resistance in EC is important in the development of novel therapies. Methods: In this study, ten paracancerous and ten tumor tissues were collected to measure the expression of insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3) and high-mobility group protein 1 (HMGA1). AN3CA and Ishikawa cells were used to explore the effects of IGF2BP3 on EC. Results: The expression levels of IGF2BP3 and HMGA1 were higher in EC tumor tissues than in paracancerous tissues. IGF2BP3 and HMGA1 are highly expressed in cisplatin-resistant EC cells. IGF2BP3 knockdown decreased the growth of cisplatin-resistant EC cells. Knockdown of IGF2BP3 decreased the level of HMGA1 protein. HMGA1 knockdown decreased the growth of cisplatin-resistant EC cells. Discuss and conclusions: The findings demonstrate that IGF2BP3 is upregulated in EC and closely regulates the growth of drug-resistant EC cells via HMGA1. The findings will inform the development of novel therapies for EC.

Heterotopic pregnancy: a case report of intrauterine hydatidiform mole with tubal pregnancy

We herein report a rare case of simultaneous intrauterine molar pregnancy and tubal pregnancy. A woman of childbearing age who had never been pregnant underwent an ultrasound examination 70 days after the onset of menopause. She had a history of ovulation induction. The ultrasound findings suggested a partial hydatidiform mole. She was then pathologically confirmed to have a complete hydatidiform mole after uterine suction dilation and curettage. On postoperative day 4, an ultrasound examination before discharge showed an inhomogeneous mass in the left adnexal region with mild lower abdominal pain. On postoperative day 17, the blood human chorionic gonadotropin level did not drop as expected, and a follow-up examination still indicated a mass in the left adnexal region. We were unable to rule out an ectopic hydatidiform mole. Hysteroscopy with laparoscopic exploration of the left adnexal mass and salpingotomy suggested a diagnosis of intrauterine hydatidiform mole combined with left tubal pregnancy.

Clinical outcomes of fetal ovarian masses diagnosed by prenatal ultrasonography and literature review

With the advancement of prenatal examination technology, more and more fetus with ovarian masses are diagnosed. However, whether such children need intervention measures after delivery, there is no more unified diagnosis and treatment measures in the world. In this study, postnatal data and clinical outcome of fetal diagnosed with ovarian masses were analyzed. We also combined with relevant literature to explore the postpartum intervention measures and timing of such children. A total of 57 cases of abdominal masses from the reproductive system were included in the study. These children were diagnosed with ovarian masses after birth. We collected from 2012 to 2020, the prenatal examination revealed the presence of abdominal masses from the reproductive system, and diagnosis was confirmed by imaging examinations after childbirth. We counted the fetal period data of these children, compared the changes in the postnatal pathology and intervention measures. A total of 57 cases of ovarian masses were diagnosed prenatally, 1 case was lost to follow-up, and 56 cases were finally included in the study. After birth a total of 21 cases of ovarian masses were treated conservatively, of which 18 cases resolved spontaneously during the follow-up process, with an average follow-up period of 30.88 ± 18.16 weeks. There were statistically significant differences in the nature and the maximum diameter of the mass between the two groups receiving conservative treatment or surgical treatment after delivery (P < .05).Univariate and multivariate Logistic regression analysis showed that there were significant differences in the nature and diameter of the mass between two groups (P < .05). In addition, we divided the children undergoing postpartum surgery into a laparoscopic surgery group and a conventional open surgery group. Through data analysis, we found that there were statistically significant differences in the age of operation, operation time, and hospitalization days in the two groups of these children (P < .05). Children diagnosed with ovarian masses prenatally generally have a good prognosis. For these children, the treatment plan should be developed according to the child general condition. If child with ovarian mass is treated with surgery, the preservation of ovarian tissue should be emphasized regardless of the size, nature, and torsion of the mass.

Circular RNA hsa_circ_0000730 restrains cell proliferation, migration, and invasion in cervical cancer through miR‐942‐5p/PTEN axis

AbstractCircular RNAs (circRNAs) play prominent roles in regulating the progression of cancers. This study is aimed to decipher the role of hsa_circ_0000730 in cervical cancer (CC).The differentially expressed circRNAs of CC were screened out from the Gene Expression Omnibus database. qRT‐PCR was used to detect circ_0000730 expression in CC tissues and cell lines, and the Kaplan–Meier curve was adopted to figure out the relationship between circ_000730 expression and the overall survival time of CC patients. BrdU assay and Tanswell assay were utilized to examine the proliferation, migration, and invasion of CC cells. Western blot was adopted to detect PTEN protein expression. Bioinformatics analysis and dual‐luciferase reporter assay were used to examine the target relationship between miR‐942‐5p and circ_0000730 or PTEN, respectively.Circ_0000730 was among the differentially expressed circRNAs in CC. Circ_0000730 was significantly down‐regulated in the cancer tissues of 50 CC patients and CC cell lines. Additionally, underexpression of circ_0000730 was associated with the shorter survival time of CC patients. Gain‐ and loss‐of‐function assays highlighted that circ_0000730 significantly inhibited the proliferation, migration, and invasion of CC cells. Mechanistically, miR‐942‐5p was identified as a downstream target of circ_0000730, and circ_0000730 could positively regulate PTEN expression via repressing miR‐942‐5p in CC cells.Circ_0000730 inhibits the proliferation, migration, and invasion of CC cells via regulating miR‐942‐5p/PTEN axis. Circ_0000730 probably acts as a tumor suppressor in CC, and it may be a candidate target for the treatment of CC.
