Cells serve as basic units of life and represent intricate biological molecular systems. The vast number of cellular molecules with their signaling and regulatory circuitries forms an intertwined network. In this network, each pathway interacts non-linearly with others through different intermediates. Thus, the challenge of manipulating cellular functions for desired outcomes, such as cancer eradication and controlling viral infection lies within the integrative system of regulatory circuitries. By using a closed-loop system control scheme, we can efficiently analyze biological signaling networks and manipulate their behavior through multiple stimulations on a collection of pathways. Specifically, we aimed to maximize the reactivation of Kaposi's Sarcoma-associated Herpesvirus (KSHV) in a Primary Effusion Lymphoma cell line. The advantage of this approach is that it is well-suited to study complex integrated systems; it circumvents the need for detailed information of individual signaling components; and it investigates the network as a whole by utilizing key systemic outputs as indicators.
细胞是生命的基本单位,代表着复杂的生物分子系统。大量的细胞分子及其信号和调节回路构成了一个相互交织的网络。在这个网络中,每条通路通过不同的中间产物与其他通路非线性地相互作用。因此,操纵细胞功能以达到预期结果(如消除癌症和控制病毒感染)的挑战在于调节回路的综合系统内。通过使用闭环系统控制方案,我们可以有效地分析生物信号网络,并通过对一系列通路的多次刺激来操纵它们的行为。具体来说,我们旨在最大限度地激活原发性渗出性淋巴瘤细胞系中的卡波西肉瘤相关疱疹病毒(KSHV)。这种方法的优点是非常适合研究复杂的综合系统;它避免了对单个信号成分详细信息的需求;并通过利用关键的系统输出作为指标来研究整个网络。
