The present research aimed to evaluate the expression of insulin-like growth factor-1 (IGF-1) in uterine leiomyoma, and explore its relationship with the occurrence and development of uterine leiomyoma and potential signal pathways. qRT-PCR and enzyme-linked immunosorbent assay were used for estimating the levels of IGF-1 in human uterine leiomyoma compared to myometrium. The expression of cell proliferation and PI3K/AKT/mTOR signaling pathway-related proteins in uterine leiomyoma cells was evaluated by western blot. Cell viability analysis was performed by CCK-8 assay. Lentivirus infection was used for IGF-1 overexpression and knockdown in uterine leiomyoma cells. The IGF-1 expression level was elevated in human uterine leiomyomas compared to myometrium. IGF-1 promoted the cell viability of human uterine leiomyoma cells. Overexpression of IGF-1 induced the expression of pro-proliferation markers including c-Myc, PCNA, and cyclin D1 in uterine leiomyoma cells. IGF-1 elevated the phosphorylation levels of PI3K, AKT, and mTOR, thus modifying PI3K/AKT/mTOR signaling in uterine leiomyoma cells. IGF-1 promotes proliferation of human uterine leiomyoma cells via PI3K/AKT/mTOR pathway.

Background: Masses in the right ventricle are uncommon, but if present, they are most often attributed to either primary cardiac tumors or metastatic disease.
Case Summary: A 50-year-old woman presented with progressive lower extremity edema and was diagnosed with a right ventricular mass causing severe tricuspid insufficiency and near-total obstruction of the pulmonary artery. She had a history of hysterectomy for uterine leiomyomatosis.

Hysteroscopic resection is considered the gold standard treatment for the removal of submucous uterine leiomyoma (SMLs). However, when hysteroscopic equipment is unavailable, alternative treatment approaches must be explored. In this case report, we present a video demonstrating the transcervical resection of an SML performed under transabdominal ultrasonography guidance on a patient with persistent abnormal uterine bleeding.

Background: Cardiac leiomyomas are extremely rare cardiac anomalies. Among them, primary leiomyomas confined to heart are even rarer, which have been reported only in few cases. Once diagnosed, surgical resection is the most common choice for treatment.

While there have been efforts to understand the mechanism behind this pathophysiology, it largely remains unclear. Lack of preclinical animal models that recapitulate aberrant steroid hormone pathways in UL has significantly hampered the development of long-term hormonal therapies for uterine fibroids.

Leiomyomas are the most common benign mesenchymal tumors of the esophagus, and they account for nearly two-thirds of benign esophageal neoplasms. The leiomyomas of the esophagus present with numerous nonspecific symptoms and signs, including dysphagia, shortness of breath, anorexia, weight loss, chronic cough, and bowel obstruction. The patient in this case report presented with moderate to severe right upper quadrant pain and mild dysphagia, which initially prompted evaluation for hepatobiliary pathology.
