ABSTRACT

TRAF2 and NCK interacting kinase (TNIK), a critical interacting protein kinase, is currently receiving wide attention. TNIK is found in various human body organs and tissues and participates in cell motility, proliferation, and differentiation. On the one hand, its aberrant expression is related to the onset and progression of numerous malignant tumors. On the other hand, TNIK is important in neuronal growth, proliferation, differentiation, and synaptic formation. Thus, the novel therapeutic strategies for targeting TNIK offer a promising direction for cancer, neurological or psychotic disorders. Here, we briefly summarized the biological information of TNIK, reviewed the role and regulatory mechanism in cancer and neuropsychiatric diseases, and introduced the research progress of inhibitors targeting TNIK. Taken together, this review hopes to contribute to the in-depth understanding of the function and regulatory mechanism of TNIK, which is of great significance for revealing the role of TNIK in the occurrence and treatment of diseases.

ABSTRACT

In a previous study, we used metabolomic techniques to identify a new metabolite of Danshen Dripping Pills called isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate (IDHP), which has potential as a drug candidate for cardiovascular diseases. This study aimed to explore the protective effects of IDHP against septic myocardial injury, as well as its molecular mechanism. Wild type or GAS6 knockout mice injured by cecal ligation and puncture (CLP) were used to observe the effect of IDHP. Here, we found that a specific concentration of IDHP (60 mg/kg) significantly increased the survival rate of septic mice to about 75 % at 72 h post CLP, and showed improvements in sepsis score, blood biochemistry parameters, cardiac function, and myocardial tissue damage. Furthermore, IDHP inhibited myocardial oxidative stress, inflammatory response, apoptosis, and mitochondrial dysfunction. Molecularly, we discovered that IDHP treatment reversed the CLP-induced downregulation of GAS6, Axl, and p-AMPK/AMPK expression. In addition, GAS6 knockout reversed the positive effect of IDHP in septic mice, indicated by more severe myocardial tissue damage, oxidative stress, inflammatory response, and mitochondrial dysfunction. GAS6 knockout also resulted in decreased levels of GAS6, Axl, and p-AMPK/AMPK. Taken together, our study provides evidence that IDHP has significant cardioprotective effects against sepsis by regulating the GAS6/Axl-AMPK signaling pathway. This finding has important therapeutic potential for treating sepsis.

ABSTRACT

Cerebral injury is closely associated with enhanced oxidative stress. A newly discovered secretory adipocytokine, intelectin-1 (ITLN-1), has been shown to have beneficial effects in neuroprotection in epidemiological studies. However, the specific molecular mechanism of ITLN-1 in protecting against cerebral oxidative stress needs further investigation. In this study, we hypothesize that ITLN-1 plays a protective role against oxidative stress injury through the SIRT1/PGC1-α signaling pathway in neuromatocytes. We used hydrogen peroxide (H2 O2 ) as a oxidative stress model to simulate oxidative stress injury. Then, small interfering RNAs (siRNAs) was used to knock down SIRT1 in N2a cells with or without ITLN overexpression, followed by H2 O2 -induced injury. We observed that H2 O2 injury significantly decreased the levels of ITLN-1, SIRT1, and PGC-1α. However, ITLN overexpression reversed H2 O2 -induced decline in cell viability and rise in apoptosis and intracellular ROS levels in N2a cells, while ITLN siRNA worsened the neurocyte injury. Furthermore, SIRT1 knockdown reversed the positive effect of ITLN overexpression on oxidative stress injury in N2a cells. Taken together, these findings suggest that ITLN-1 exerts neuroprotective effects against oxidative stress injury primarily through the SIRT1/PGC-1α axis.

ABSTRACT

The NOD-like receptor protein 3 (NLRP3) inflammasome is a protein complex that regulates innate immune responses by activating caspase-1 and the inflammatory cytokines interleukin (IL)-1ß and IL-18. Multiple studies have demonstrated the importance of the NLRP3 inflammasome in the development of immune and inflammation-related diseases, including arthritis, Alzheimer's disease, inflammatory bowel disease, and other autoimmune and autoinflammatory diseases. This review first explains the activation and regulatory mechanism of the NLRP3 inflammasome. Secondly, we focus on the role of the NLRP3 inflammasome in various inflammation-related diseases. Finally, we look forward to new methods for targeting the NLRP3 inflammasome to treat inflammation-related diseases, and provide new ideas for clinical treatment.

ABSTRACT

Ageing is a physiological/pathological process accompanied by the progressive damage of cell function, triggering various ageing-related disorders. Phosphatidylinositol 3-kinase (PI3K), which serves as one of the central regulators of ageing, is closely associated with cellular characteristics or molecular features, such as genome instability, telomere erosion, epigenetic alterations, and mitochondrial dysfunction. In this review, the PI3K signalling pathway was firstly thoroughly explained. The link between ageing pathogenesis and the PI3K signalling pathway was then summarized. Finally, the key regulatory roles of PI3K in ageing-related illnesses were investigated and stressed. In summary, we revealed that drug development and clinical application targeting PI3K is one of the focal points for delaying ageing and treating ageing-related diseases in the future.
