概括
缺氧诱导因子1-α (HIF-1α) 的表达在口腔状细胞癌 (OSCC) 瘤岛和侵入性前线之间有所不同. 较高的HIF-1α与侵入性前端的Vimentin相关,这表明在OSCC进展中发挥了作用.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 口腔癌中的缺氧通过表皮细胞-介质细胞过渡促进了瘤的侵袭.
- 这一过程有助于在口腔状细胞癌 (OSCC) 中的侵袭性瘤进展.
研究的目的:
- 在OSCC中,描述缺氧诱导因子1-alpha (HIF-1α) 在侵袭性瘤前线 (ITF) 与瘤岛屿 (TI) 的表达.
- 在OSCC中研究HIF-1α,E-cadherin和Vimentin表达之间的关系.
主要方法:
- 免疫组织化学用于评估HIF-1α,Vimentin和E-cadherin表达在38个OSCC病例和5个正常口腔粘膜 (NOM) 样本中.
- 免疫光和免疫反应评分分析了蛋白质表达水平.
- 侵入性瘤前端 (ITF) 根据区域和AE1/AE3免疫表达被确定.
主要成果:
- 与侵袭性瘤前部 (ITF) (P = 0.0134) 和正常的口腔粘膜 (P = 0.0115).相比,HIF-1α表达在瘤岛 (TI) 中显著更高.
- 在ITF地区,HIF-1α表达与Vimentin表达有显著的相关性 (P = 0.017).
- 增加的HIF-1α水平与侵入性边缘的维丁表达率升高有关.
结论:
- HIF-1α在OSCC瘤进展中表现出不同的作用.
- 在ITF调查低氧驱动的细胞表型变化对于理解OSCC至关重要.
- 需要进一步的研究来阐明这些发现在OSCC中的预后影响.

Regulation of Angiogenesis and Blood Supply
2.7K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Adaptive Mechanisms in Cancer Cells
5.9K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Tumor Progression
6.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Cell Migration through Invadopodia
2.4K
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,...

Cancer Therapies
7.9K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
