Article Abstract
The planar cell polarity (PCP) signaling pathway, principally understood from work in Drosophila, is now known to contribute to development in a broad swath of the animal kingdom, and its impairment leads to developmental malformations and diseases affecting humans. The 'core' mechanism underlying PCP signaling polarizes sheets of cells, aligning them in a head-to-tail fashion within the sheet. Cells use the resulting directional information to guide a wide variety of processes. One such process is lateralization, the determination of left-right asymmetry that guides the asymmetric morphology and placement of internal organs. Recent evidence extends the idea that PCP signaling underlies the earliest steps in lateralization and that PCP is invoked again during asymmetric morphogenesis of organs including the heart and gut.

Aim: Prickle planar cell polarity (PCP) protein 2 (Prickle2) encodes a homologue of Drosophila prickle and is involved in the non-canonical Wnt/PCP signalling pathway. However, its exact role in dentinogenesis remains unclear. Dentinogenesis, a key process in tooth morphogenesis, involves the patterned arrangement of odontoblasts and the formation of dentine matrix along the pulp cavity.

Thrombocytopenia-Absent Radius (TAR) syndrome is a rare congenital condition with reduced platelets, forelimb anomalies, and variable heart and kidney defects. TAR syndrome is caused by mutations in RBM8A/Y14, a component of the exon junction complex. How perturbing a general mRNA-processing factor causes the selective TAR Syndrome phenotypes remains unknown.

Neural tube defects (NTDs), such as anencephaly and spina bifida, are prevalent congenital anomalies of the central nervous system. These defects can give rise to severe lifelong disabilities and incur substantial healthcare expenses for the affected individuals. The occurrence of NTDs is caused by multiple factors, including molecular regulatory mechanisms and environmental factors.

Context: Breast cancer metastasis remains a significant challenge in oncology, necessitating novel therapeutic approaches. Rac1 is a small GTPase involved in Wnt-planar cell polarity (Wnt-PCP) signaling and modulation of endoplasmic reticulum (ER) stress, and it has emerged as a promising target for inhibiting cancer progression. This study investigates the potential of cinnamaldehyde, a bioactive compound derived from cinnamon bark, as a potential Rac1 inhibitor.
