Sepsis-induced acute kidney injury (SAKI) is a common complication of hospitalized patients, often leading to unacceptable mortality. Limited effective treatment or diagnosis biomarkers are available and the underlying mechanism remains unclear. The miR-30c-5p is considered as a critical mediator of kidney diseases and aberrantly decreased in patients with SAKI, while the mechanism is still unclear. For this purpose, the role of miR-30c-5p in SAKI has been investigated in this study. Here, we first confirmed that miR-30c-5p expression decreased in our septic models and was associated with the activation of NLRP3/caspase-1-mediated pyroptosis. Overexpression of miR-30c-5p alleviated the kidney injury via suppressing HK-2 cell pyroptosis. Furthermore, we identified that TXNIP was a direct target of miR-30c-5p. Upregulation of miR-30c-5p repressed the expression of TXNIP, which inhibited NLRP3, ASC, and caspase-1 expression, as well as secretion of inflammatory cytokines. In conclusion, our data suggested that miR-30c-5p negatively controlled the NLRP3 signal pathway-related pyroptosis and sepsis-induced injury via TXNIP, indicating that this axis might be a positive therapeutic target for the patient with SAKI.
The aim of the present study was to determine the effect of microRNA (miR)-155-5p on the expression of testican-1 (SPOCK1) and the invasion and migration of prostate cancer cells
in vitro
. Bioinformatics analysis and molecular biology assays revealed that SPOCK1 may be a direct target gene of miR-155-5p. In addition, a negative correlation was identified between SPCOK1 and miR-155-5p expression in prostate tumor tissues and cell lines. miR-155-5p mimic transfection inhibited SPOCK1 expression in PC3 cells and decreased cell migration and invasion abilities, while the expression of vimentin, N-cadherin, E-cadherin, β-catenin, matrix metalloproteinase (MMP)3 and MMP9 was upregulated. In summary, SPOCK1 was found to be a target gene of miR155-5p in prostate cancer, and miR-155-5p acts as a tumor-suppressor gene and may inhibit SPOCK1-mediated prostate cancer progression.
BACKGROUND
Primary prostate Burkitt's lymphoma is a rare and aggressive condition with a poor prognosis. Its clinical presentation can be challenging to differentiate from benign prostatic hyperplasia. Given the rarity of primary prostate Burkitt's lymphoma, its diagnosis and treatment remain unclear.
CASE SUMMARY
This report presents a case of a 57-year-old male with primary prostate Burkitt's lymphoma, initially misdiagnosed as prostatic hyperplasia. This case's operative process, intraoperative findings and postoperative management are discussed in detail.
CONCLUSION
Primary prostate lymphoma is difficult to distinguish from other prostate diseases. Holmium laser enucleation of the prostate (HoLEP), a minimally invasive procedure, is crucial in diagnosing and treating this rare disease. Clinicians should remain vigilant and thoroughly combine physical examination, imaging and test results when encountering patients of younger age with small prostate size but a rapid progression of lower urinary tract symptoms. HoLEP is an essential diagnostic and therapeutic tool in managing primary prostate Burkitt's lymphoma.
Renal medullary carcinoma is a rare and aggressive malignancy that commonly occurs in young African men with sickle cell disease. we report a case of a 64-year-old female patient with left renal medullary carcinoma who was hospitalized for severe hydronephrosis due to upper ureteral calculi obstruction. A laparoscopic left nephrectomy was performed, and the tumor was pathologically diagnosed with renal medullary carcinoma. Postoperative pain was not significantly relieved and the patient developed retroperitoneal metastasis 1 month later and died after 3 months of follow-up. For elderly patients with long-term kidney stones and altered kidney morphology, renal tumors should be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
