概括

虹膜素是一种参与能量代谢的蛋白质,不影响黑色素瘤细胞增殖. 然而,它减少了特定黑色素瘤细胞的入侵和MMP-2/MMP-9活性,这表明它在癌症进展中起着不同的作用.

科学领域:

内分泌学在内分泌学.
在瘤学瘤学.
分子生物学分子生物学

背景情况:

虹膜素是一种新型肌蛋白,与能量代谢有关.
它在癌症信号通路中的作用已得到认可,但其在转移性黑色素瘤中的特定功能仍未得到充分研究.

研究的目的:

研究素对转移性黑色素瘤 (MM) 细胞体外模型的生物效应.
为了确定虹膜素对MM细胞增殖,入侵和相关的酶活性的影响.

主要方法:

治疗MM细胞系 (HBLwt/wt,LND1wt/wt,Hmel1V600K/wt,M3V600E/V600E) 用不同度的复合性虹膜素 (r-虹膜素).
扩散的MTT测定,入侵测定,MMP-2/MMP-9活性的凝组图,以及MMP和纤维溶解因子的基因表达的qPCR.

主要成果:

在测试度中,r-Irisin并没有显著改变MM细胞的增殖.
在LND1wt/wt细胞中观察到显著的侵袭能力减少,这些细胞表达高αv基因水平.
用10nM的r-irisin治疗降低了BRAF野生型细胞中的MMP-2和MMP-9酶活性和基因表达,同时抑制了亲侵入性纤维解质系统.

结论:

虹膜蛋白对转移性黑色素瘤细胞表现出差异性影响,可能取决于BRAF突变状态和αv表达.
在特定的黑色素瘤情况下,虹膜素可能在抑制侵袭和矩阵金属蛋白酶活性方面发挥作用,这需要进一步调查.

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Selectins

Selectins

Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

The Ras Gene

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...
