概括
这项研究确定了三种分泌基因 (ITGB5,TIMP1,TMEM176B),可以区分侵袭性前列腺癌 (PCa) 和惰性PCa. 这些生物标志物可以帮助患者避免误诊和过度治疗.
科学领域:
- 癌症学
- 分子生物学
- 生物标志物发现
背景情况:
- 由于缺乏非侵入性生物标志物,将侵袭性前列腺癌 (PCa) 与惰性PCa区分开来是具有挑战性的,这可能导致误诊和过度治疗.
- 鉴定新型分泌蛋白质对于开发准确分类PCa亚型的工具至关重要.
研究的目的:
- 鉴定和验证能区分前列腺癌的侵袭性和惰性基因.
- 研究这些基因和 ΔC499 在巨分化和 PCa 侵入性的作用.
主要方法:
- 在PCa组织群中使用微阵列进行基因表达分析.
- 在体外,体内和患者样本中研究分泌基因 ΔC499 和巨分化之间的关系.
- 开发和验证PCa亚型的多基因分泌特征模型.
主要成果:
- 在侵略性PCa中观察到ITGB5的上调和TIMP1/TMEM176B的下调,这与M2巨分化有关.
- 发现 ΔC499 通过促进 ITGB5 驱动的 M2 巨分化来增强 PCa 侵袭.
- 一个三基因特征 (ITGB5,TIMP1,TMEM176B) 准确地区分了惰性PCa与高AUC值 (0.88- 0.90).
结论:
- 已识别的三基因特征作为一种潜在的非侵入性生物标志物,用于区分攻击性PCa和惰性PCa.
- ΔC499通过ITGB5,TIMP1和TMEM176B的调节对PCa的侵入性起作用,影响M2巨细胞的极化.

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Cancer Cell Migration through Invadopodia
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...

The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
