Correlation between oncogene integrator complex subunit 7 and a poor prognosis in lung adenocarcinoma

BackgroundLung adenocarcinoma (LUAD) is one of the most common types of cancer worldwide with high incidence and mortality rates. The integrator complex subunit 7 (INTS7) encodes a subunit of the integrator complex that mediates small-nuclear ribonucleic acid (RNA) processing and has been shown to be associated with RNA polymerase II. However, the clinical significance of INTS7 in LUAD is still not clear and needs to be investigated.MethodsThe single-cell sequencing of a publicly available data set was conducted to compare the expression levels and percentages of INTS7 in lung malignant cells at different classifications and stages. Further, 33 cancer types from The Cancer Genome Atlas (TCGA) database were analyzed, protein-protein interaction (PPI) networks were constructed, and functional annotations were undertaken for the INTS7 gene. INTS7 small-interfering RNAs were transfected into LUAD cell lines, and cell biological behaviors, such as migration, invasion, apoptosis and proliferation capacity, were then examined.ResultsWe found that the expression of INTS7 was significantly more upregulated in the LUAD tissues than the adjacent normal tissues. Increased INTS7 messenger RNA expression was correlated with TNM (tumor node metastasis classification) stage and gender in LUAD patients. Further, the Kaplan-Meier survival analysis indicated that LUAD patients with high INTS7 expression levels had a worse prognosis than those with low INTS7 expression levels. Finally, we found that silencing INTS7 inhibited LUAD cell viability and invasion in vitro.ConclusionsThese results suggest that INTS7 can be used as a potential therapy target and prognostic marker for LUAD. Further, INTS7 may aggravate migration and invasion, induce the proliferation, and attenuate the apoptosis capacity of cells in LUAD.

Unusual morphologic features of low‐grade endometrial stromal sarcoma: A case report

BackgroundEndometrial stromal tumours are uncommon tumours of the uterus. They mainly occur in perimenopausal women. Tumours with typical clinicopathological features do not usually pose diagnostic problems. However, rare clinicopathological features can occur, and clinicians without significant experience may have difficulty diagnosing these tumours and managing these patients.MethodsHerein, we report a case of endometrial stromal sarcoma that occurred in a 25‐year‐old woman. The pathological features, immunophenotype, treatment and prognosis were discussed.ResultsThe tumour revealed morphological heterogeneity, and there were similar proliferative‐type endometrial stromal cells, an extensive amount of mature adipose tissue, and prominent rhabdomyoblastic and smooth muscle cells. Histopathological and immunohistochemical studies confirmed low‐grade endometrial stromal sarcoma with smooth muscle, adipocytic and rhabdomyoblastic differentiation (approximately 60% were differentiated tissues). The final treatment of the tumour was total abdominal hysterectomy with bilateral salpingo‐oophorectomy. There was no evidence of recurrence for 109 months postoperatively.ConclusionsWe found that low‐grade endometrial stromal tumours with extensive adipocytic and prominent rhabdomyoblastic differentiation are misdiagnosed because they are infrequent. They must be differentiated from rhabdomyosarcoma with accurate identification of adipocytes, and long‐term follow‐up is needed.
