A Wnt-Wnt Situation

Activation of the Wnt Pathway by Mycobacterium tuberculosis: A Wnt–Wnt Situation

Mycobacterium tuberculosis (M. tuberculosis), an intracellular pathogenic Gram-positive bacterium, is the cause of tuberculosis (TB), a major worldwide human infectious disease. The innate immune system is the first host defense against M. tuberculosis. The recognition of this pathogen is mediated by several classes of pattern recognition receptors expressed on the host innate immune cells, inc...

The Canonical Wnt Signaling (Wnt/β-Catenin Pathway): A Potential Target for Cancer Prevention and Therapy

Precise regulation of signal transduction pathways is crucial for normal animal development and for maintaining cellular and tissue homeostasis in adults. The Wnt/Frizzled-mediated signaling includes canonical and non-canonical signal transduction pathways. Upregulation or downregulation of the canonical Wnt-signaling (or the Wnt/β-Catenin signal transduction) leads to a variety of human diseas...

نقش مسیر سیگنالینگ Wnt/-catenin در لوسمی‌های خونی

چکیده سابقه و هدف مسیر سیگنالینگ Wnt/β-catenin ، یکی از آبشارهای کلیدی مهم در تنظیم سیر تکاملی و پایداری سلول‌های ایمنی و خون است، اما نقش دقیق آن هنوز بحث‌ برانگیز و موضوع پژوهش‌های مختلفی است. با فعال­ شدن مسیر سیگنالینگ Wnt، پروتئین β-catenin به داخل هسته وارد شده و رونویسی ژن­های هدف شاملcyclin D1 و c-myc را فعال می­کند. مسیر سیگنالینگ Wnt/β-catenin کانونیکال در سرطان­های خونی به طور غیرعا...

From individual Wnt pathways towards a Wnt signalling

From individual Wnt pathways towards a Wnt signalling network.

Wnt proteins play important roles during vertebrate and invertebrate development. They obviously have the ability to activate different intracellular signalling pathways. Based on the characteristic intracellular mediators used, these are commonly described as the Wnt/beta-catenin, the Wnt/calcium and the Wnt/Jun N-terminal kinase pathways (also called planar cell polarity pathway). In the past...
