Zheng F, Wang J, Wang D, Yang Q. Clinical Application of Small Extracellular Vesicles in Gynecologic Malignancy Treatments. Cancers (Basel) 2023; 15:cancers15071984. [PMID: 37046644 PMCID: PMC10093031 DOI: 10.3390/cancers15071984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 03/22/2023] [Accepted: 03/24/2023] [Indexed: 03/29/2023] Open
Abstract
Small extracellular vesicles (sEVs) are the key mediators of intercellular communication. They have the potential for clinical use as diagnostic or therapeutic biomarkers and have been explored as vectors for drug delivery. Identification of reliable and noninvasive biomarkers, such as sEVs, is important for early diagnosis and precise treatment of gynecologic diseases to improve patient prognosis. Previous reviews have summarized routine sEVs isolation and identification methods; however, novel and unconventional methods have not been comprehensively described. This review summarizes a convenient method of isolating sEVs from body fluids and liquid biopsy-related sEV markers for early, minimally invasive diagnosis of gynecologic diseases. In addition, the characteristics of sEVs as drug carriers and in precision treatment and drug resistance are introduced, providing a strong foundation for identifying novel and potential therapeutic targets for sEV therapy. We propose potential directions for further research on the applications of sEVs in the diagnosis and treatment of gynecologic diseases.

[PMID: 35578572 PMCID: PMC9761094 DOI: 10.1002/cam4.4828] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 04/10/2022] [Accepted: 04/18/2022] [Indexed: 02/03/2023] Open
Abstract
Cervical cancer (CC) ranks as the fourth most frequently diagnosed malignancy in females worldwide. Exosomes are a subclass of extracellular vesicles released by nearly all types of cells that act as cargo transport vehicles, carrying proteins, and genetic material (such as miRNAs, long noncoding RNAs, and mRNAs) derived from their parent cells may affect receiving cells and thus have emerged as key players in several biological processes, including inflammatory pathways. In this review, we concentrated on the findings of exosome investigations in CC, particularly their components. They direct the actions of CC cells by inducing surface molecules associated with various biological pathways. We summarized the current knowledge of exosomal RNAs and proteins from CC cells and discussed the feasibility of exosomes as potential biomarkers for CC. We suggest that cancer-derived exosomes promote metastasis in CC by supporting EMT, controlling the proliferation, invasion, or migration of cancer cells, as well as influencing immune escape and aiding angiogenesis. Overall, cancer-derived exosomes are critical in the progression of CC, and further studies are necessary to advance our understanding of the clinical value of exosomes in CC.

Transl Pediatr 2021; 10:1890-1895. [PMID: 34430437 PMCID: PMC8349947 DOI: 10.21037/tp-21-291] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 07/14/2021] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Previous researches have suggested that LINC00673 rs11655237 C>T polymorphism might be correlated to cancer susceptibility. However, its correlation with pediatric glioma is unknown. Therefore, this study aimed to determine whether LINC00673 rs11655237 C>T polymorphism is correlated with pediatric glioma. METHODS In total, we included 399 subjects from South China. The Student's t-test was performed to evaluate age differences between glioma cases and controls. Differences in the categorical variables between the two groups were assessed using the χ2 test. A logistic regression was conducted to calculate the odds ratio (OR) and the 95% confidence interval (CI). RESULTS We conducted this case-control study to investigate the association between LINC00673 polymorphism and pediatric glioma susceptibility. Our results revealed that LINC00673 rs11655237 C>T polymorphism was not correlated to pediatric glioma susceptibility in a Chinese population (CC/CT compared with TT: adjusted OR =2.49, 95% CI: 0.87-7.15, P=0.091). Furthermore, a stratified analysis also indicated LINC00673 rs11655237 C>T polymorphism did not increase the risk of glioma in different subgroups. CONCLUSIONS Our study revealed that LINC00673 rs11655237 C>T polymorphism was not correlated to pediatric glioma susceptibility in a Chinese population. In the future, further exploration of this genetic factor in relation to glioma susceptibility will require a larger sample size to verify the current findings.

Wang S, Guo Y, Zhang X, Wang C. miR‑654‑5p inhibits autophagy by targeting ATG7 via mTOR signaling in intervertebral disc degeneration. Mol Med Rep 2021; 23:444. [PMID: 33846806 PMCID: PMC8060800 DOI: 10.3892/mmr.2021.12083] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 02/15/2021] [Indexed: 01/07/2023] Open
Abstract
Intervertebral disc degeneration (IDD) is a common chronic disease characterized by the loss of extracellular matrix (ECM) in the nucleus pulposus (NP). Accumulating evidence has revealed that abnormal expression of microRNAs (miRs) is closely associated with IDD development. The present study aimed to investigate the precise role and possible mechanism underlying the effects of miR‑654‑5p in the pathogenesis of IDD. NP cells were isolated from patients with IDD. Monodansylcadaverine staining was conducted to reveal cell autophagy, while western blotting was performed to detect the expression of ECM‑related proteins in NP cells. Luciferase reporter and RNA immunoprecipitation assays were conducted to identify the binding between RNAs. The results demonstrated that miR‑654‑5p was significantly upregulated in degenerated NP tissues from patients with IDD and high miR‑654‑5p expression was positively associated with disc degeneration grade. Functional assays suggested that miR‑654‑5p facilitated ECM degradation by increasing the expression levels of MMP‑3, MMP‑9 and MMP‑13, as well as decreasing collagen I, collagen II, SOX9 and aggrecan expression by inhibiting autophagy. Furthermore, autophagy‑related gene 7 (ATG7) was verified as a direct downstream target gene of miR‑654‑5p. miR‑654‑5p could bind to the 3' untranslated region of ATG7 to inhibit its mRNA expression and further reduce its translation. Notably, ATG7 knockdown abrogated the effects of the miR‑654‑5p inhibitor on ECM degradation and autophagy regulation. Furthermore, miR‑654‑5p inhibited autophagy in NP cells by increasing the protein expression levels of phosphorylated (p)‑PI3K, p‑AKT and p‑mTOR in an ATG7‑dependent manner. In conclusion, the results of the present study revealed that miR‑654‑5p may enhance ECM degradation via inhibition of autophagy by targeting ATG7 to activate the PI3K/AKT/mTOR signaling pathway. These findings may provide novel insights into the treatment of IDD.

Abstract
Objective To study the expression of LINC00673 in cervical cancer and cervical intraepithelial neoplasia (CIN) and to explore the role of LINC00673 in the development of cervical cancer. Methods The expression of LINC00673 in serum from cervical cancer patients, CIN patients, and healthy participants was detected by RT-qPCR. The function of LINC00673 in cervical cancer cells was analyzed using in vitro and in vivo experiments. Results Our results revealed that serum LINC00673 levels were highest in cervical cancer patients, followed by patients with CIN and healthy controls. In vitro experiments demonstrated that overexpression of LINC00673 enhanced the proliferation and cell cycle progression of HeLa and SiHa cells. In vivo experiments showed that the tumor weight and volume of nude mice subcutaneously injected with LINC00673-overexpressing HeLa cells were larger than those of nude mice injected with control cells (P < 0.05). Western blotting showed that cell cycle-related proteins cyclin A2 and cyclin E and interstitial-associated proteins Snail and N-cadherin were upregulated and p53 signaling pathway-related proteins were downregulated in LINC00673-overexpressing HeLa and SiHa cells. Conclusion LINC00673 plays an important role in the development of cervical cancer and may serve as a new therapeutic target for cervical cancer.

Abstract
Long non-coding RNAs (LncRNAs) act as regulators and play important roles in a variety of biological processes. These regulators constitute a huge information network among genes and participate in the pathophysiological process of human diseases. Increasing evidence has demonstrated that LncRNA, as an oncogene or tumor suppressor gene, is closely related to the occurrence and development of tumors. Linc00673 is a recently discovered LncRNA molecule that is dysregulated in several solid tumors. Moreover, its genetic polymorphism is believed to affect the susceptibility of a population to the corresponding cancer species. This article summarizes the role of Linc00673 in different human cancers and its molecular mechanisms with a focus on the characteristics of Linc00673 and the existing literature on it while highlighting the future research directions for Linc00673. Linc00673 has the potential to become a feasible clinical diagnostic and prognostic marker toward providing a new molecular therapeutic target for cancer patients.
