概括

拉巴胺素复合体2 (TORC2) 途径的目标,特别是RICT-1,促进了C. elegans的幼虫生殖系干细胞的增殖. 肠道TORC2通过维原蛋白起作用,将营养感应与干细胞发育联系起来.

科学领域:

细胞生物学细胞生物学
发展生物学发展生物学
分子生物学分子生物学

背景情况:

像干细胞和瘤这样的增殖细胞对营养物质有反应.
保守的拉帕素标 (TOR) 途径调节细胞对营养素的反应.
TOR存在于两个复合体:TORC1 (特征很好) 和TORC2 (在生殖线发育中不太了解).

研究的目的:

研究TORC2在生殖线发育中的作用.
确定TORC2组成部分RICT-1如何影响干细胞增殖.
阐明TORC2在生殖线中的功能背后的信号通路和分子机制.

主要方法:

使用*Caenorhabditis elegans*作为一个模型生物.
采用了遗传分析和RNA测序 (RNA-seq).
研究了RICT-1的功能及其下游效应物,如SGK-1和维特洛根因.

主要成果:

RICT-1通过SGK-1促进幼虫生殖线前代区域 (PZ) 的扩张,通过SGK-1发挥作用.
肠 *rict-1* 对于生殖线 PZ 的建立至关重要和足够,与生殖线自主 TORC1.1 不同.
RICT-1的作用独立于DAF-2/IIS和DAF-7/TGF-ß通路,但涉及肠道产生的维特洛因素 (例如*vit-3*).

结论:

这项研究揭示了TORC2在调节幼虫发育期间干细胞增殖中的新角色.
肠道TORC2信号传递,由维特洛金因介导,将营养物质的可用性与生殖干细胞扩张联系起来.
*C. elegans*生殖系作为研究TORC2,干细胞和脂质代谢的有价值模型.

Renewal of Intestinal Stem Cells

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
