概括

高血糖与前列腺癌 (PCa) 的发展和改变的微RNA (miRNA) 水平有关. 这项研究在高血糖PCa患者中发现了特定的miRNA失调,这表明在癌症进展中发挥了作用.

科学领域:

生物化学生化学
在瘤学瘤学.
分子生物学分子生物学

背景情况:

高血糖是前列腺癌 (PCa) 发展的已知危险因素.
微RNAs (miRNAs) 在PCa患者的表达模式与健康个体相比呈现差异.
在PCa中高血糖和miRNA表达之间的相互作用仍然是积极研究的领域.

研究的目的:

在前列腺癌 (PCa) 患者中研究高血糖和尿液中特定miRNA水平之间的关系.
为了比较PCa患者和非癌症对照患者的miRNA表达特征,具有不同的血糖值.
在PCa和高血糖症的背景下,探索miRNA水平,葡萄糖和前列腺特异抗原 (PSA) 之间的相关性.

主要方法:

实时定量PCR被用来测量7种尿路miRNAs (miR-574-3p,miR-375,miR-205-5p,miR-200b-3p,miR-187-3p,miR-182-5p,miR-100-5p) 的相对表达.
从105名PCa患者和138名非癌症对照者的临床记录中获得了禁食血糖水平.
统计分析包括差异表达的非参数测试和与葡萄糖和PSA相关的皮尔森相关性.

主要成果:

在高血糖的非癌症对照中观察到miR-200b-3p,miR-187-3p,miR-182-5p和miR-100-5p的显著下调.
与高葡萄糖的对照组相比,高血糖PCa患者显示出显著的miRNA失调,miR-375和miR-182-5p明显上调.
在控制组和PCa组中确定了特定miRNA和葡萄糖/PSA之间的相关性,这表明了潜在的生物标志物.

结论:

miRNA失调与高血糖前列腺癌 (PCa) 患者有关.
过高血糖似乎促进了miR-375和miR-182-5p的表达,可能有助于PCa的发展.
无法控制的高血糖可能会通过通过miRNAs改变基因表达,为PCa进展创造有利的微环境.

MicroRNAs

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Psychoneuroimmunology: Diabetes and Cancer

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
