The hepatoprotective effect of aspirin on carbon tetrachloride‑induced hepatic fibrosis via inhibition of TGFβ‑1 pathway and pro‑inflammatory cytokines IL‑1β and COX‑2 in rats.

Aspirin decreases liver fibrosis index and inflammation levels. However, the exact mechanism underlying the effects of aspirin are yet to be elucidated. The aim of the study was to investigate the potential protective effects of aspirin on carbon tetrachloride (CCl)-induced hepatic fibrosis in Sprague-Dawley rats.

Cyclin-Dependent Kinase 5 Regulatory Subunit Associated Protein 3: Potential Functions and Implications for Development and Disease.

Cyclin-dependent kinase 5 (CDK5) regulatory subunit associated protein 3 (CDK5RAP3, also named as C53 or LZAP) was initially identified as a binding protein of CDK5 activator p35. To date, CDK5RAP3 has been reported to interact with a range of proteins involved in cellular events ranging from cell cycle, apoptosis, and invasion to UFMylation modification and endoplasmic reticulum stress. Owing to its crucial roles in cellular processes, CDK5RAP3 is demonstrated to be not only an active participant in embryonic and mammalian tissue development, but also a key regulator in the onset and progress of human cancers such as head and neck squamous cell carcinoma, gastric cancer, hepatocellular cancer, lung cancer, kidney cancer and breast cancer.

Protein Phosphorylation in Cancer: Role of Nitric Oxide Signaling Pathway.

Nitric oxide (NO), a free radical, plays a critical role in a wide range of physiological and pathological processes. Due to its pleiotropic function, it has been widely investigated in various types of cancers and is strongly associated with cancer development. Mounting pieces of evidence show that NO regulates various cancer-related events, which mainly depends on phosphorylating the key proteins in several signaling pathways.

Effects of non-drug treatment on liver cells apoptosis during hepatic ischemia-reperfusion injury.

Hepatic ischemia reperfusion injury (HIRI) is an important cause of liver dysfunction after liver transplantation for the patients suffered from fatty liver, non-alcoholic cirrhosis, or liver cancer. It is closely related to liver cells apoptosis. Therefore, how to maintain the stable state of cell apoptosis is important to protect the liver from HIRI.

Pharmacological Treatment of Vascular Dementia: A Molecular Mechanism Perspective.

Vascular dementia (VaD) is a neurodegenerative disease, with cognitive dysfunction attributable to cerebrovascular factors. At present, it is the second most frequently occurring type of dementia in older adults (after Alzheimer's disease). The underlying etiology of VaD has not been completely elucidated, which limits its management.

Lrp4 in hippocampal astrocytes serves as a negative feedback factor in seizures.

Background: Epilepsy is characterized by the typical symptom of seizure, and anti-seizure medications are the main therapeutic method in clinical, but the effects of these therapy have not been satisfactory. To find a better treatment, it makes sense to further explore the regulatory mechanisms of seizures at genetic level. Lrp4 regionally expresses in mice hippocampus where is key to limbic epileptogenesis.

New insights into BMP9 signaling in organ fibrosis.

Fibrosis is a common endpoint for chronic organic diseases. Many signaling pathways and cytokines are involved in the development of fibrosis. Recently, bone morphogenetic protein 9 (BMP9), a member of transforming growth factor-beta (TGF-β) superfamily, has been considered as a pivotal regulator in tissue fibrosis, and exerts its diverse effects on the activation of fibroblasts and the development of fibrotic diseases.

Exploring the bi-directional relationship between autophagy and Alzheimer's disease.

Alzheimer's disease (AD) is characterized by β-amyloid (Aβ) deposition and Tau phosphorylation, in which its pathogenesis has not been cleared so far. The metabolism of Aβ and Tau is critically affected by the autophagy. Abnormal autophagy is thought to be involved in the pathogenesis of AD, regulating autophagy may become a new strategy for AD treatment.

Risk Factors, Mechanisms and Treatments of Thromboangiitis Obliterans: An Overview of Recent Research.

Background: Thromboangiitis obliterans (TAO) is a nonatherosclerotic thromboticocclusive vasculitis that affects the vessels of the small and medium-sized extremities. No explicit etiology or pathogenesis of TAO has been proven, and more effective treatments are needed.

Objective: The study aimed to summarize and present an overview of recent advances regarding the risk factors, mechanisms and treatments of TAO and to organize the related information in figures to provide a comparatively complete reference.

Effects of apoptosis on liver aging.

As an irreversible and perennial process, aging is accompanied by functional and morphological declines in organs. Generally, aging liver exhibits a decline in volume and hepatic blood flow. Even with a preeminent regenerative capacity to restore its functions after liver cell loss, its biosynthesis and metabolism abilities decline, and these are difficult to restore to previous standards.

Roles of aging in sleep.

With aging, various factors deteriorate the normal sleep process that is essential for the restoration of functional and physical performance. Due to aging-related diseases, life changes, or aging itself, disturbances in normal sleep cycles can profoundly affect healthy aging. To understand the interconnections between aging and the factors influencing sleep, with emerging evidence accumulated in recent years, this study elaborates on the roles of aging in sleep from four perspectives: cortical thinning, white matter degeneration, neurotransmitter dysregulation, and circadian disorganization.

Similarity in the functions of HIF-1α and HIF-2α proteins in cervical cancer cells.

Hypoxia is a common feature of many solid tumours, including cervical cancer. Aggressive tumour progression is mostly associated with hypoxia. Furthermore, hypoxic conditions in tumours are also associated with resistance to chemotherapy and radiation, and with poor prognosis.

Health: a dream from reality to the future.

This paper argues that health is a realistic productive force that may enhance the index of happiness. As the basis of all developments and the source of a person's and his/her family's happiness, health requires not only primary and secondary prevention, but also policy prevention, that is to say, grade-zero prevention. Therefore, people should pay more attention to Health in All Policies.

Postconditioning and remote postconditioning of ischemic rat cardiac grafts.

Background: Global warm ischemia of transplanted cardiac grafts is associated with apoptosis and subsequent tissue necrosis. It is suggested that postconditioning (PostC) may ameliorate the early outcome of cardiac grafts after ischemia-reperfusion. We investigated whether PostC and remote postconditioning (RPostC) have a histopathologic impact after transplantation of warm ischemic rat cardiac grafts.
