生物标志物研究生物标志物研究

背景情况:

肺腺癌是全球癌症死亡的主要原因之一.
个性化治疗需要预测生物标志物来改善患者的治疗结果.
甲状腺转录因子-1 (TTF-1) 和表皮生长因子受体 (EGFR) 是肺癌发展的关键因素.

研究的目的:

在摩洛哥肺腺癌患者中研究TTF-1表达和EGFR突变之间的相关性.
评估TTF-1和EGFR作为互补的诊断和治疗生物标记物的潜力.
分析这些生物标志物与临床病理学参数和生存率的相关性.

主要方法:

预期招收234名肺腺癌患者 (2017-2022年).
用于TFT-1表达分析的免疫组织化学.
用于检测EGFR突变的分子测试 (包括19号外因子缺失和21号外因子突变).
关联的统计分析与临床病理学数据和整体存活率.

主要成果:

在83.8%的病例中观察到TTF-1表达,女性和从未吸烟者更高.
在21.36%的患者中发现了EGFR突变;19个外基因的缺失是最常见的 (15.38%).
在TTF-1表达和EGFR突变 (p < 0.001) 之间发现了显著的关联,特别是19个外因子的删除 (p = 0.009).

结论:

在摩洛哥肺腺癌中,TTF-1表达与常见的EGFR突变,特别是19号外因子缺失有很强的相关性.
这种关联在从未吸烟者中最明显,突出显示TTF-1和EGFR是互补的生物标志物.
建议进行进一步的多中心研究,以验证其预后意义并指导治疗决策.

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.

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...
