The kidney plays a fundamental role in the regulation of arterial blood pressure and fluid/electrolyte homeostasis. As congenital anomalies of the kidney and urinary tract (CAKUT) constitute one of the most common human birth defects, improved understanding of the cellular and molecular mechanisms that lead to CAKUT is critical. Accumulating evidence indicates that aberrant signaling via receptor tyrosine kinases (RTKs) is causally linked to CAKUT. Upon activation by their ligands, RTKs dimerize, undergo autophosphorylation on specific tyrosine residues, and interact with adaptor proteins to activate intracellular signal transduction pathways that regulate diverse cell behaviours such as cell proliferation, survival, and movement. Here, we review the current understanding of role of RTKs and their downstream signaling pathways in the pathogenesis of CAKUT.

Epidermal growth factor receptor (EGFR) plays an important role in the regulation of cell proliferation and migration [1]. It forms a homodimer or heterodimer with other ErbB receptor family members to activate downstream signaling. Emerging evidence indicates that the EGFR activity and downstream signaling are regulated by other proteins except its family members during tumorigenesis.

This study aimed to evaluate the efficacy of pyrotinib, an orally administered small molecule tyrosine kinase inhibitor, combined with neoadjuvant chemotherapy in treating patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Pyrotinib works by inhibiting the HER2 signaling pathway, thereby preventing tumor cell growth. This single-arm clinical trial aimed to assess the total pathological complete response (tpCR; ypT0/is and ypN0) rate as the primary endpoint.

Background: Intestinal Behçet's syndrome (IBS) has high morbidity and mortality rates with serious complications. However, there are few specific biomarkers for IBS. The purposes of this study were to investigate the distinctive metabolic changes in plasma samples between IBS patients and healthy people, active IBS and inactive IBS patients, and to identify candidate metabolic biomarkers which would be useful for diagnosing and predicting IBS.

Based on the focal adhesion kinase(FAK)/steroid receptor coactivator(Src)/extracellular regulated protein kinase(ERK) pathway, this study explored the effects of Xihuang Pills on angiogenesis, invasion, and metastasis in prostate cancer. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to analyze and identify the active ingredients of Xihuang Pills. Bioinformatics techniques, including R language and Perl programs, were employed to analyze the interactions between prostate cancer-related targets and the potential targets of Xihuang Pills.
