Summary: Primary cilia function as sensory organelles that monitor extracellular signals and transduce them into intracellular responses. Actin and microtubule networks play critical roles in primary ciliogenesis and maintenance. Targeting cytoskeleton-associated proteins may be a promising therapeutic strategy for treating ciliopathies.

Summary: CCDC66 is a microtubule-associated protein involved in cilium biogenesis and ciliopathies. It localizes between centrosomes, centriolar satellites, and the ciliary axoneme and tip during cilium biogenesis. Depletion of CCDC66 leads to defects in cilium assembly, length, and morphology, as well as impaired Hedgehog pathway activation. Furthermore, CCDC66 is necessary for the recruitment of transition zone proteins and intraflagellar transport B (IFT-B) machinery to the basal body. Overall, CCDC66 plays a multifaceted role in regulating the primary cilium and provides insight into the assembly of functional cilia.

Summary: The tumor suppressor gene p53 plays a critical role in preventing tumor progression, but inappropriate activation of p53 can lead to various human inherited disorders. Genes related to these disorders are involved in transcriptional regulation, DNA damage-repair pathways, and other cellular processes, which may result in excessive p53 activation and developmental defects. Mouse models have shown that inactivation of p53 can alleviate disorder-related phenotypes, and potential therapeutic strategies for genetic disorders associated with p53 misactivation are being discussed.

Summary: The DNA-PK-p53 cascade induces primary cilia formation under genotoxic stress, contributing to the DNA damage response, while lack of this pathway decreases genotoxic stress-induced ciliogenesis. Besides, ciliogenesis is regulated not only by DNA-PK, but also by autophagy.

Summary: Centrioles and cilia are essential microtubule-based structures in cells that play critical roles in cell function and development. This study identifies a new microtubule-associated protein, ENKD1, which regulates microtubule organization and stability. Furthermore, it shows that ENKD1 depletion leads to defective regulation of ciliary length and content, as well as a failure to respond to Hedgehog pathway activation.

Summary: CEP78 is a centrosomal protein involved in ciliogenesis and ciliary length control. Through interaction with other proteins like CEP350 and EDD1, CEP78 negatively regulates CP110 level to promote ciliogenesis downstream of CEP350. This discovery provides important insights into the role of CEP78 in cellular ciliogenesis.

Summary: DNA damage is a common event in every cell, and proteins of the DNA damage response network play a crucial role in sensing and repairing DNA lesions. Genetic defects in DNA repair proteins can lead to immunodeficiency, bone marrow failure syndromes, and increased cancer susceptibility. DDR biomarkers are useful for diagnosing NHEJ defects and AT, with some limitations depending on the specific DNA repair deficiency.

Summary: Primary cilia are microtubule-based protrusions surrounded by a ciliary membrane equipped with selected receptors that control important signaling pathways in cell growth and development. This review presents a model of primary ciliogenesis by an alternative route involving the midbody remnant from cytokinesis, which delivers membranes to the centrosome for ciliary membrane assembly. The involvement of the midbody remnant in primary cilium formation and its regulation by the ESCRT machinery are discussed, along with the emerging roles of membrane compartmentalization.

Summary: Resistance to chemo- and radiotherapy is a common occurrence in cancer patients, necessitating the continuous investigation and development of new cancer therapies. The DNA damage response (DDR) plays a crucial role in maintaining genomic stability, but defects in DDR machinery are associated with different types of cancers. Current developments include the use of poly (ADP-ribose) polymerase inhibitors (PARP inhibitors) as DDR inhibitors (DDRi) for various cancers. However, resistance to DDRi, including PARP inhibitors, is becoming a growing concern in clinical settings. This review highlights the importance of DDR pathways in cancer therapy, its role in treatment resistance, and its potential for anticancer treatment.

A cost-effective biocompatible alternative to commercially available polymers is reported, which forms gels at low concentrations. The differences in gelling mechanisms between the investigated polymer and Poloxamer P407 (Pluronic F127) are elucidated through nanoscale self-assembly and rheological analysis.

Summary: Chronic total occlusions (CTOs) occur in approximately 40% of individuals with symptomatic peripheral arterial disease and are indicative of critical limb ischaemia. Currently, few medical devices can effectively treat CTOs long-term, with amputation often required. This study aims to develop a workflow for further characterising the complex anatomy of CTOs and creating 3D models, which may be useful in producing a vascular CTO biomimetic for device testing. The study successfully establishes a workflow using high-resolution microcomputed tomography (mu CT) to generate 3D models of CTO components. This research holds great promise in improving device development for treating critical limb ischaemia.

Summary: In this study, the researchers found that centriolar satellite and centrosomal proteins are crucial for the formation of aggresomes and the aggregation of disease-relevant proteins. They showed that satellites are required for the growth of aggresomal structure and this growth depends on the centrosomal proteins CP110, CEP97, and CEP290.

Summary: Inherited retinal degeneration caused by the loss of photoreceptor cells is a major cause of human blindness. This study uses expansion microscopy and electron microscopy to uncover the molecular architecture of the connecting cilium (CC) and reveals that microtubules are connected by a CC inner scaffold containing POC5, CENTRIN, and FAM161A. The disruption of Fam161a leads to the loss of the CC inner scaffold, triggering microtubule doublet spreading and ultimately resulting in outer segment collapse and photoreceptor degeneration.

Summary: This study identifies RAD51 Cys319 as a functionally significant site for the redox regulation of homologous recombination (HR) and cellular responses to ionizing radiation (IR). The loss of peroxiredoxin 1 (PRDX1) inhibits RAD51 focus formation and HR DNA repair, leading to increased DNA damage and sensitization of cells to irradiation.

Summary: This study aimed to evaluate a lab-based bioreactor model for assessing bone remodelling onto, into or around new implant technologies. The results showed that the samples cultured in the bioreactor exhibited greater tissue ongrowth, ingrowth and remodelling compared to those in static culture conditions. In addition, the mechanically tested samples from the bioreactor had approximately three times greater fixation strength.

Summary: Biosensors based on graphene field effect transistors (GFETs) have the potential to develop portable diagnostic tools for early stage disease detection. By optimizing the analytical performance and test protocol, our GFET array platform can accurately detect pancreatic ductal adenocarcinoma (PDAC) in patients' plasma and differentiate different stages of cancer. The increased expression of GPC-1 cancerous exosomes leads to an improved signal response of GFET biosensors. This technology holds great promise for the rapid diagnosis of pancreatic cancer.

Summary: This study investigates the impact of disabling the autoinhibition mechanism of dynein-2 on intraflagellar transport (IFT) using genome editing techniques in Caenorhabditis elegans. The results show that retrograde transport can be reactivated in IFT-A-deficient cilia by activating dynein-2 using a "hot-wiring" approach, providing functional evidence for dynein-2 autoinhibition during anterograde IFT and establishing key roles for IFT-A in regulating retrograde transport.

Summary: The study identified WDR-60 as a key player in the recruitment and dynamics of dynein-2, with its loss leading to reduced and slower retrograde IFT trains. Disrupting the NPHP module at the transition zone almost fully restored ciliary exit of underpowered retrograde trains in wdr-60 mutants.
