以前的研究表明,miR-379的过度表达抑制了前列腺癌 (PCa) 转移在体外和体内.
在PCa转移中 miR-379 的作用背后的精确机制需要进一步阐明.

研究的目的:

研究miR-379影响前列腺癌转移的分子机制.
在与PCa相关的骨微环境模型中识别由miR-379调节的分泌蛋白质.
阐明 miR-379 ,雄激素受体 (AR) 和前列腺特异性抗原 (PSA) 在 PCa.中之间的调节关系.

主要方法:

利用细胞因子阵列在骨微环境模型中识别受miR-379失调影响的分泌蛋白质.
进行功能研究,包括记者测定,以分析转录调节.
对miR-379表达,AR水平和血清PSA之间的相关性进行评估的临床样本.

主要成果:

前列腺特异性抗原 (PSA) 分泌和细胞内水平被miR-379水平反向调节.
发现miR-379通过向AR 3'-UTR.通过向AR 3'-UTR来降低原体受体 (AR) 表达的表达,间接调节PSA转录.
临床数据显示前列腺miR-379表达和血清PSA之间存在逆相关性,并且减少miR-379与增加AR相关.
miR-379没有直接调节PSA表达.

结论:

miR-379通过抑制AR间接地对PSA分泌产生负面调节.
miR-379,AR和PSA之间的相互作用与前列腺癌的骨转移性进展有关.
这些发现突出了一个新的调节途径,可能有助于PCa病变和转移.

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...

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...

Abnormal Proliferation

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...
