Cervical Decompression Surgery for Cervical Spondylotic Myelopathy and Concomitant Hypertension: A Multicenter Prospective Cohort Study.

Study Design: We performed decompression surgery or conservative treatments on 135 cervical spondylotic myelopathy (CSM) patients with concomitant hypertension and did follow-up assessments up to 1 year to examine the change of blood pressure, spinal cord function, and cervical pain.

Objective: The aim of this study was to determine whether concomitant hypertension is relieved after decompression surgery, and whether it is related to the improvement of spinal cord function or cervical pain.

Summary Of Background Data: In clinical practice, we often found that some patients with CSM have concomitant hypertension.

Mechanoreceptors in Diseased Cervical Intervertebral Disc and Vertigo.

Study Design: We collected the samples of cervical intervertebral discs from patients with vertigo to examine the distribution and types of mechanoreceptors in diseased cervical disc.

Objective: The aim of this study was to determine whether mechanoreceptors are distributed more abundantly in cervical discs from patients with cervical spondylosis, and whether they are related to vertigo.

Summary Of Background Data: Previous limited studies have found that normal cervical intervertebral discs are supplied with mechanoreceptors that have been considered responsible for proprioceptive functions.

The PTTG1-targeting miRNAs miR-329, miR-300, miR-381, and miR-655 inhibit pituitary tumor cell tumorigenesis and are involved in a p53/PTTG1 regulation feedback loop.

Deregulation of the pituitary tumor transforming gene (PTTG1), a newly discovered oncogene, is a hallmark of various malignancies, including pituitary tumors. However, the mechanisms regulating PTTG1 expression are still needed to be explored. MicroRNAs (miRNAs) are a novel class of small RNA molecules that act as posttranscriptional regulators of gene expression and can play a significant role in tumor development.

MicroRNA-130a inhibits cell proliferation, invasion and migration in human breast cancer by targeting the RAB5A.

MiR-130a has been demonstrated to play important roles in many types of cancers. Nevertheless, its biological function in breast cancer remains largely unknown. In this study, we found that the expression level of miR-130a was down-regulated in breast cancer tissues and cells.

MicroRNA-873 (miRNA-873) inhibits glioblastoma tumorigenesis and metastasis by suppressing the expression of IGF2BP1.

Glioblastoma multiforme (GBM) is known as a highly malignant brain tumor with a poor prognosis, despite intensive research and clinical efforts. In this study, we observed that microRNA-873 (miR-873) was expressed at low levels in GBM and that the overexpression of miR-873 dramatically reduced the cell proliferation, migration, and invasion of GBM cells. Our further investigations of the inhibition mechanism indicated that miR-873 negatively affected the carcinogenesis and metastasis of GBM by down-regulating the expression of IGF2BP1, which stabilizes the mRNA transcripts of its target genes.

MiR-132, miR-15a and miR-16 synergistically inhibit pituitary tumor cell proliferation, invasion and migration by targeting Sox5.

MiR-132, miR-15a and miR-16 have been implicated in the pathogenesis of many types of cancer, including pituitary tumors. However, the molecular mechanism of these miRNAs in pituitary tumor growth and metastasis is still unclear. Here, we showed that miR-132 and miR-15a/16 were less expressed in pituitary tumor cell lines, as well as in invasive pituitary tumor tissues, compared to non-invasive tumor tissues.

USF-1 inhibition protects against oxygen-and-glucose-deprivation-induced apoptosis via the downregulation of miR-132 in HepG2 cells.

Upstream stimulatory factor 1 (USF-1) is an important transcription factor that participates in glucose metabolism and tumorigenesis. The aim of the current study was to explore the regulatory mechanism of USF-1 in HepG2 cells exposed to oxygen and glucose deprivation (OGD). After the establishment of the OGD model in HepG2 cells, we determined that the cells treated with OGD exhibited a high apoptotic rate and that the introduction of siRNA against USF-1 protected the cells from OGD-induced apoptosis.
