Exome sequencing revealed a homozygous missense variant in PIGF (NM_173074.3c.515C>G, p.Pro172Arg) in both. We demonstrate impaired glycosylphosphatidylinositol (GPI) biosynthesis through flow cytometry analysis. We thus describe the causal role of a novel disease gene, PIGF, in DOORS syndrome and highlight the overlap between this condition and GPI deficiency disorders. NSC 119875 For each gene implicated in DOORS syndrome and/or inherited GPI deficiencies, there is considerable clinical variability so a high index of suspicion is warranted even though not all features are noted.αKlotho is a type 1 transmembrane anti-aging protein. αKlotho-deficient mice have premature aging phenotypes and an imbalance of ion homeostasis including Ca2+ and phosphate. Soluble αKlotho is known to regulate multiple ion channels and growth factor-mediated phosphoinositide-3-kinase (PI3K) signaling. Store-operated Ca2+ entry (SOCE) mediated by pore-forming subunit Orai1 and ER Ca2+ sensor STIM1 is a ubiquitous Ca2+ influx mechanism and has been implicated in multiple diseases. NSC 119875 However, it is currently unknown whether soluble αKlotho regulates Orai1-mediated SOCE via PI3K-dependent signaling. Among the Klotho family, αKlotho downregulates SOCE while βKlotho or γKlotho does not affect SOCE. Soluble αKlotho suppresses serum-stimulated SOCE and Ca2+ release-activated Ca2+ (CRAC) channel currents. Serum increases the cell-surface abundance of Orai1 via stimulating vesicular exocytosis of the channel. The serum-stimulated SOCE and cell-surface abundance of Orai1 are inhibited by the preincubation of αKlotho protein or PI3K inhibitors. Moreover, the inhibition of SOCE and cell-surface abundance of Orai1 by pretreatment of brefeldin A or tetanus toxin or PI3K inhibitors prevents further inhibition by αKlotho. Functionally, we further show that soluble αKlotho ameliorates serum-stimulated SOCE and cell migration in breast and lung cancer cells. These results demonstrate that soluble αKlotho downregulates SOCE by inhibiting PI3K-driven vesicular exocytosis of the Orai1 channel and contributes to the suppression of SOCE-mediated tumor cell migration.TGF-β1 is a major mediator of airway tissue remodelling during atopic asthma and affects tight junctions (TJs) of airway epithelia. However, its impact on TJs of ciliated epithelia is sparsely investigated. Herein we elaborated effects of TGF-β1 on TJs of primary human bronchial epithelial cells. We demonstrate that TGF-β1 activates TGF-β1 receptors TGFBR1 and TGFBR2 resulting in ALK5-mediated phosphorylation of SMAD2. We observed that TGFBR1 and -R2 localize specifically on motile cilia. TGF-β1 activated accumulation of phosphorylated SMAD2 (pSMAD2-C) at centrioles of motile cilia and at cell nuclei. This triggered an increase in paracellular permeability via cellular redistribution of claudin 3 (CLDN3) from TJs into cell nuclei followed by disruption of epithelial integrity and formation of epithelial lesions. Only ciliated cells express TGF-β1 receptors; however, nuclear accumulations of pSMAD2-C and CLDN3 redistribution were observed with similar time course in ciliated and non-ciliated cells. In summary, we demonstrate a role of motile cilia in TGF-β1 sensing and showed that TGF-β1 disturbs TJ permeability of conductive airway epithelia by redistributing CLDN3 from TJs into cell nuclei. We conclude that the observed effects contribute to loss of epithelial integrity during atopic asthma.

Advances in cancer treatment have led to longer cancer-free periods and overall survival. This study aimed to understand patients‘ experiences of transitioning out of a state of believing to be cancer free into incurable recurrence with advanced disease.

Using constructivist grounded theory with in-depth interviews patients (n = 15) with solid tumors from a major US cancer center participated. Theoretical sampling enabled concepts to be developed until theme saturation. Constant comparative analysis used initial and focused coding to develop themes and concepts to describe this specific period from extended time cancer free and transition to advanced incurable disease.

Three interrelated concepts were identified reluctant acceptance, seeking survival through continuous treatment, and hope in the face of an uncertain future. A conceptual model of the experience was developed encompassing anger and sadness, at initial recurrence, to reluctant acceptance, and, finally, a cycle of seeking continuous treatment to prolong life leading to a sense of hope in the face of an uncertain future.

The cycle between treatment and hope creates a state of personal equilibrium, which provides insights into the importance of treatment for this population. This study provides direction for future research to understand the expectations of people experiencing advanced cancer recurrence.

Many cancer survivors live with advanced cancer. Assessing their needs as they transition from survivor with no disease to survivor with advanced disease requires a new conceptualization of the experience which recognizes expectations and priorities for care of this patient group.

Being a parent alongside a cancer diagnosis presents unique challenges. It is unclear to what degree parenting considerations feature in routine care and how doctors approach treatment decision discussions.

To explore doctor perspectives regarding patients with cancer who have dependent children.

Focus groups and interviews conducted to ascertain doctor views. Responses were audio-recorded, transcribed and thematically analysed.

Twenty-eight doctors participated medical oncology (7), haematology (10), palliative care (8), and psycho-oncology (3). Participants observed cancer impacted upon parenting across several domains psycho-social, practical, and family implications. Having dependent children was perceived to influence the patient experience and decision-making by patients and clinicians. Participants identified this cohort as emotionally demanding to care for with a range of psychological effects identified for doctors, particularly in highly challenging circumstances (single-parent and non-English speaking families, scenarios involving communication difficulties).

Participants recognised the presence of dependent children to profoundly influence the experience of being both a parent and a patient with cancer. Identifying patients with parental responsibilities was noted as relevant for management at diagnosis through to death. link2 link2 Greater understanding of doctors‘ experiences providing care for this cohort may inform the development of resources to assist doctors and their patients.

Sexual life is a multidimensional issue that can be affected negatively after gynecological cancer. The aim of this study was to reveal what sexuality life difficulties Iranian women with gynecological cancers experience.

A qualitative approach was conducted through face-to-face semi-structured interviews with 16 Iranian women with gynecological cancer and then analyzed with conventional content analysis.

Three themes emerged from the data (1) participant’s struggle to maintain the sexual monopoly of the husband, (2) deterioration of intimacy, and (3) unpleasant bed-life experiences. Most women are ashamed to talk about their sexual relationships problems, and on the other hand, nurses and physicians ignore to talk about their sexual problems, so these women are alone in the face of this problem.

Although women with gynecological cancer experience sexual problems such as reluctant to have sex and lack of enjoyment, they struggle to maintain sexual life with their husbands. These women do not have enough support. They believe that sexuality is a shameful issue, and they are reluctant to ask questions about it. Health professionals need to talk about the possibility of sexual problems due to changes in their bodies caused by cancer. These women need to be encouraged to talk about these problems, with consideration to their religious and cultural differences.

This study explores healthcare professionals (HCPs)‘ perception and current management of sleep disturbance (SD) in people with malignant brain tumours and their caregivers. We aimed to identify barriers to effective management of SD in neuro-oncology care.

We conducted semi-structured interviews with 11 HCPs involved in neuro-oncology care. The study was underpinned by the Capability Opportunity Motivation-Behaviour (COM-B) model within the Behavioural Change Wheel (BCW) guiding topic selection for the exploration of underlying processes of HCPs‘ behaviours and care decisions for SD management. Data were analysed thematically using a framework synthesis, and subsequently mapped onto the BCW to identify barriers for effective management and recommend potential interventions.

We identified four themes HCPs‘ clinical opinions about SD, the current practice of SD management in neuro-oncology clinics, gaps in the current practice, and suggested areas for improvements. HCPs perceived SD as a prevalent yet se are experiencing SD.Pseudomonas syringae pv. link3 tabaci 6605 (Pta6605) is a causal agent of wildfire disease in host tobacco plants and is highly motile. Pta6605 has multiple clusters of chemotaxis genes including cheA, a gene encoding a histidine kinase, cheY, a gene encoding a response regulator, mcp, a gene for a methyl-accepting chemotaxis protein, as well as flagellar and pili biogenesis genes. However, only two major chemotaxis gene clusters, cluster I and cluster II, possess cheA and cheY. Deletion mutants of cheA or cheY were constructed to evaluate their possible role in Pta6605 chemotaxis and virulence. Motility tests and a chemotaxis assay to known attractant demonstrated that cheA2 and cheY2 mutants were unable to swarm and to perform chemotaxis, whereas cheA1 and cheY1 mutants retained chemotaxis ability almost equal to that of the wild-type (WT) strain. Although WT and cheY1 mutants of Pta6605 caused severe disease symptoms on host tobacco leaves, the cheA2 and cheY2 mutants did not, and symptom development with cheA1 depended on the inoculation method.
