During the course of tumor progression, cancer cells acquire a number of characteristic alterations. These include the capacities to proliferate independently of exogenous growth-promoting or growth-inhibitory signals, to invade surrounding tissues and metastasize to distant sites, to elicit an angiogenic ...
In cancer cells, oncogenic signalling pathways deregulate the activity of the SREBP transcription factors and MVA pathway enzymes. Deregulated production of MVA pathway metabolites modulates multiple signalling pathways in cancer cells and contributes to transformation. Clinical trials to evaluate the utility...
Cancer cells are cells gone wrong — in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy. Over time, these cells become increasingly ...
The NTP found what it calls “clear evidence” thattwo different types of cell phone signals, GSM and CDMA, increased the incidence of malignant tumors in the hearts of male ratsover the course of the two-year study. Higher incidences of brain and adrenal tumors were also seen, but ...

正常细胞需要有丝分裂生长信号(growth signals, GS)才能从静止状态进入活跃的增殖状态。这些信号通过结合不同类型的信号分子的跨膜受体传递到细胞中:扩散生长因子、细胞外基质成分和细胞间粘附/相互作用分子。据我们所知,没有任何一种正常细胞能在没有这种刺激信号的情况下增殖。癌症目录中的许多癌基因都以这样或那样的...
Therapy resistance is a major problem when treating cancer patients as cancer cells develop mechanisms that counteract the effect of therapeutic compounds, leading to fit and more aggressive clones that contribute to poor prognosis. Therapy resistance can be both intrinsic and/or acquired. These are ...
2024年3月11日,北京大学生命科学学院杨竞团队在Cell Research上发表题为: Multiple cancer cell types release LIF and Gal3 to hijack neural signals的研究性论文。 神经信号对肿瘤预后有显著影响。然而,癌细胞如何主动调节神经系统以使其自身存活尚不完全清楚。在这项研究中,作者报告了在多种外周癌症小鼠模型中一...
