The primary cilium is generally a non-motile solitary organelle that protrudes from a basal body at the cell surface in various cell types in multicellular organisms. This microtubule-based structure acts as a cell signaling platform to control key cellular processes, including cell proliferation and differentiation in development and in adult tissues. Elongated and/or dysfunctional primary cilia cause developmental disorders termed ciliopathies and cancers. The genetic inhibition of ciliogenesis inducers can block the progression of these diseases in model organisms. Thus, pharmacological inhibition of primary ciliogenesis has emerged as a potential strategy to treat these pathological conditions. Pharmacological inhibitors that affect cilium assembly, and have an impact on other cellular processes, have been identified. Here, we review some of these tools and discuss their value and limitations in the study of primary cilium biology, as well as for the treatment of some ciliopathies and cancers.

Prostate cancer (PCa) is one of the most common malignancies for male individuals globally. Androgen deprivation therapy (ADT) initially demonstrated significant efficacy in treating PCa; however, most cases of PCa eventually progress to castration-resistant prostate cancer (CRPC), which becomes increasingly challenging to manage. Notably, the loss or disruption of primary cilia in PCa cells may play a critical role in the progression of the disease, and there are no reports on the role of circular RNAs in ciliogenesis.

The primary cilium is a crucial signaling organelle that can be generated by most human cells, and impediments to primary ciliogenesis lead to a variety of developmental disorders known as ciliopathies. The removal of the capping protein, CP110, from the mother centriole is a crucial early step that promotes generation of the ciliary vesicle and ciliogenesis. Recent studies have demonstrated that CP110 undergoes polyubiquitination and degradation in the proteosome, but the mechanisms of unfolding and removal from the mother centriole remain unknown.

Inositol polyphosphate-5-phosphatase E (INPP5E) is a 5-phosphatase critically involved in diverse physiological processes, including embryonic development, neurological function, immune regulation, hemopoietic cell dynamics, and macrophage proliferation, differentiation, and phagocytosis. Mutations in cause Joubert and Meckel-Gruber syndromes in humans; these are characterized by brain malformations, microphthalmia, situs inversus, skeletal abnormalities, and polydactyly. Recent studies have demonstrated the key role of INPP5E in governing intracellular processes like endocytosis, exocytosis, vesicular trafficking, and membrane dynamics.

Folic acid (FA) supplementation is a potent tool to reduce devastating birth defects known as neural tube defects (NTDs). Though effective, questions remain how FA achieves its protective effect and which gene mutations are sensitive to folic acid levels. We explore the relationship between FA dosage and NTD rates using NTD mouse models.

Article Synopsis
- The primary cilium is a crucial organelle involved in various signaling pathways, and its dysfunction is linked to conditions like Bardet-Biedl syndrome, Alzheimer's, and autism, all of which can lead to cognitive impairment.
- Researchers studied the effects of temporarily disabling the IFT88 gene, vital for cilia formation, in adult mice to understand cilia's role in brain activity.
- The findings showed that mice lacking functional cilia had significant learning deficits and abnormal brainwave patterns, emphasizing the importance of primary cilia for proper neural function and memory in adults.
