OBJECTIVE
We investigated whether inhibition of hedgehog (Hh) signal by cyclopamine attenuated inflammation and cartilage damage in adjuvant-induced arthritis (AIA) rats.
METHODS
Cyclopamine (2.5, 5, 10 mg/kg) was given by intraperitoneal injection once daily from day 12 to 21 after AIA induction.
Although layered double hydroxides (LDH) have been listed as promising nanomaterials in human healthcare, very little has been achieved on osteoblast inflammatory signaling. Thus, osteoblasts were challenged with two LDHs (Mg2Al-Cl and Zn2Al-Cl, at 0.002 mg/mL) up to 24 h, establishing an acute
Chronic obstructive pulmonary disease (COPD) is a persistent airway inflammation influenced by cigarette smoke. Previous studies have reported that Hedgehog (Hh) signaling is aberrantly activated by cigarette smoke and dysregulated in COPD. The present study explored the role of the Hh signaling
Purmorphamine (PUR), an agonist of the Smoothened (Smo) receptor, has been shown to function as a neuroprotectant in acute experimental ischemic stroke. Its role in hypoxic-ischemic (HI) brain injury in neonatal mice remains unknown. Here we show that PUR attenuated acute brain injury, with a
To investigate the inflammatory effect of Interleukin 18 (IL-18) on rat chondrocytes and the involvement of Wnt/β-catenin and Hedgehog pathways, the mRNA and protein level of matix-degrading enzymes (MMP-2, 3, 9,13 and aggrecanses) and chondrocyte-specific proteins (Collagen II and aggrecan) were
Background: Poststroke depression (PSD) is the most frequent psychological sequela after stroke. Electroacupuncture (EA) treatment is effective for PSD. The study aimed at clarifying the mechanisms of EA's antidepressant effects in a PSD rat model. Methods: We used middle cerebral
Cholestasis is a significant risk factor for immediate hepatic failure due to ischemia reperfusion (I/R) injury in patients undergoing liver surgery or transplantation. We recently demonstrated that inhibition of Hedgehog (Hh) signaling with cyclopamine (CYA) before I/R prevents liver injury. In
OBJECTIVE
Lipid accumulation, inflammatory responses and oxidative stress have been implicated in the pathology of alcoholic liver disease (ALD). Targeting inhibition of these features may provide a promising therapeutic strategy for ALD. Baicalin, a flavonoid isolated from Scutellaria baicalensis
The adult mammalian brain responds to injury by activating a program of cell proliferation during which many oligodendrocyte precursors, microglia, and some astrocytes proliferate. Another common response to brain injury is the induction of reactive gliosis, a process whereby dormant astrocytes
BACKGROUND
We have earlier found a highly efficient induction of the differentiation of epidermal lineage skin tumors by cyclopamine, a steroidal alkaloid inhibitor of the hedgehog/smoothened signaling, under conditions in which cyclopamine exerted no adverse effect on skin.
OBJECTIVE
We aimed to
The blood brain barrier (BBB) is a diffusion barrier that maintains the brain environment. Wip1 is a nuclear phosphatase induced by many factors and involved in various stresses, tumorigenesis, organismal aging, and neurogenesis. Wip1's role in BBB integrity has not been thoroughly investigated. The
BACKGROUND
Nociceptive sensitization is a tissue damage response whereby sensory neurons near damaged tissue enhance their responsiveness to external stimuli. This sensitization manifests as allodynia (aversive withdrawal to previously nonnoxious stimuli) and/or hyperalgesia (exaggerated
BACKGROUND
We previously showed that type X collagen, a marker of late stage chondrocyte hypertrophy (associated with endochondral ossification), is constitutively expressed by mesenchymal stem cells (MSCs) from osteoarthritis patients and this may be related to Naproxen (Npx), a nonsteroidal
UNASSIGNED
The hedgehog signaling system (HHS) plays an important role in the regulation of cell proliferation and differentiation during the embryonic phases. However, little is known about the involvement of HHS in the malignant transformation of cells. This study aimed to detect the role of HHS
BACKGROUND
Psoriasis is a chronic inflammatory disorder of skin characterized by hyperproliferation of keratinocytes. Intracellular signalling pathways inducing the hyperproliferation of keratinocytes remain to be elucidated. An inhibitor of Hedgehog (Hh) signalling, cyclopamine, was recently
