概括

原蛋白II类型的端可以损害人类关节软骨,增加矩阵金属蛋白酶 (MMP) 和蛋白质甘氨酸损失. 通过整合蛋白β-1 (ITGB1) 信号传递,C-端可能会调解这种损伤.

科学领域:

生物化学生物化学
整形外科整形外科整形外科
细胞生物学细胞生物学

背景情况:

骨关节炎 (OA) 涉及关节软骨的退化.
在OA病变发生过程中,II型原蛋白的作用还没有完全被理解.
研究telopeptide诱导的软骨损伤对于理解OA至关重要.

研究的目的:

为了确定II型原体端是否诱导骨关节炎组织损伤.
为了研究telopeptide受体在这个过程中的作用.
分析涉及到telopeptide介导的软骨分解的分子机制.

主要方法:

使用了人类关节软骨和初级状细胞培养物.
培养物被用N-telopeptide (NT) 或C-telopeptide (CT) 处理.
测量了蛋白质甘氨酸损失,MMP-3,MMP-13和整合蛋白β-1 (ITGB1) 表达.

主要成果:

无论是NT还是CT都显著诱导了来自软骨的蛋白质甘氨酸损失.
NT和CT上调矩阵金属蛋白酶 (MMP),特别是MMP-3和MMP-13.
与NT相比,CT治疗导致ITGB1在冠状细胞中的表达更强.

结论:

原体II型的端可以损害人类的关节软骨.
泰洛提升MMP-3和MMP-13的调节,这是软骨降解中的关键酶.
通过ITGB1.1,C-端的催化作用可能会通过ITGB1.1进行调解.

Growth of Cartilage and Bone Tissue

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Type IV Collagen of Basal Lamina

Type IV Collagen of Basal Lamina

Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can...

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Nervous Tissue: Neuron Types

Nervous Tissue: Neuron Types

Neurons, the fundamental units of the nervous system, can be classified based on both their structural and functional characteristics.
Structurally, neurons are categorized into three main types: multipolar, bipolar, and unipolar (or pseudounipolar). Multipolar neurons, which are the most common type in the brain and spinal cord, as well as all motor neurons, possess multiple dendrites and a single axon.
Bipolar neurons, on the other hand, have one primary dendrite and one axon. They are...

Connective Tissue Cell Types

Connective Tissue Cell Types

Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Fibril-associated Collagen

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
