Analgesic effects of TLR4/NF-κB signaling pathway inhibition on chronic neuropathic pain in rats following chronic constriction injury of the sciatic nerve.
Chronic neuropathic pain (CNP) is attributed to a lesion or disease of the somatosensory system, may be derived from the peripheral and central system. Recent study revealed that spinal cord stimulation attenuated CNP by inhibiting TLR4/NF-κB signaling pathway. The present study focuses on the potential analgesic effects of TLR4/NF-κB signaling pathway on CNP in a rat model of chronic constriction injury (CCI). ⋯ Collectively, this study defines the role of TLR4 and NF-κB, and inhibition of TLR4/NF-κB signaling pathway might contribute to the alleviation of CNP and improvement of MWT and TWL in a rat model of CCI. Additionally, the results obtained from the study provided a promising basis that could aid as an experimental basis for the potential treatment of TLR4/NF-κB signaling pathway.

Long non-coding RNA SNHG5 sponges miR-26a to promote the tumorigenesis of osteosarcoma by targeting ROCK1.
Osteosarcoma (OS) is one of the most common invasive malignancies of the bone. The long non-coding RNA (lncRNA) SNHG5 (small nucleolar RNA host gene 5) has been consistently shown to be involved in many cancers, although its precise function in osteosarcoma remains poorly understood. In this study, we investigated the role of SNHG5 in OS progression and the underlying mechanism. ⋯ SNHG5 acts as an oncogene in OS via the SNHG5-miR-26a-ROCK1 axis and is therefore a potential novel therapeutic target for OS treatment.

LINC01116 targets miR-520a-3p and affects IL6R to promote the proliferation and migration of osteosarcoma cells through the Jak-stat signaling pathway.
The purpose of this study was to find out the important lncRNA-miRNA-mRNA axis and pathway in osteosarcoma (OS) through bioinformatics analysis and verify the biological functions of lncRNA/miRNA/mRNA in OS through in vitro and in vivo assays. ⋯ LINC01116 up-regulated IL6R in OS through targeting miR-520a-3p, thus activating the Jak-stat signaling pathway and promoting the progression of OS.

Standardized Ginkgo biloba extract EGb 761® attenuates early brain injury following subarachnoid hemorrhage via suppressing neuronal apoptosis through the activation of Akt signaling.
Early brain injury (EBI) plays a critical role in determining the outcome of subarachnoid hemorrhage (SAH). The present study was designed to investigate the role of EGb 761, a standardized extract of Ginkgo biloba, in SAH-induced EBI and to explore its potential mechanism of action. ⋯ Our results indicated that EGb 761 could ameliorate SAH-induced EBI and that the neuroprotective effects of EGb 761 against SAH were exerted via suppression of neuronal apoptosis through activation of the Akt pathway.

Targeting of TRX2 by miR-330-3p in melanoma inhibits proliferation.
This study is intended to identify the key gene from gene expression profile and validate its role and regulatory mechanism in melanoma. ⋯ Inhibiting TPX2 by miR-330-3p suppresses the proliferation of melanoma cell lines. miR-330-3p/TPX2 pathway could be a potential therapeutic target in melanoma.
