Overexpression of these molecular chaperones is linked with tumor survival, metastasis and anticancer drug resistance. In recent years, heat shock proteins are gaining much importance in the field of cancer research owing to their potential to be key determinants of cell survival and apoptosis. Lung cancer is one of the most common cancers diagnosed worldwide and the association of heat shock proteins in lung cancer diagnosis, prognosis and as drug targets remains unresolved. The aim of this review is to draw the importance of heat shock protein members; Hsp27, Hsp70, Hsp90, Hsp60 and their diagnostic and prognostic implications in lung cancer. Based on the available literature heat shock proteins can serve as biomarkers and anticancer drug targets in the management of lung cancer patients.Periodontitis is a bacteria-driven inflammatory destructive disease that leads to attachment loss, bone resorption, and even tooth loss. Accumulating studies revealed that macrophages might play an nonnegligible role during the processes of periodontitis. Epacadostat in vivo However, the underlying mechanism remains largely unknown. In this study, we found novel Akt2/JNK1/2/c-Jun and Akt2/miR-155-5p/DET1/c-Jun signaling pathways that regulated the polarization of macrophages and altered periodontal inflammatory status. Through hematoxylin and eosin, immunostaining, and immunofluorescence staining of clinical specimens, a higher number of M1 phenotype macrophage infiltration was found in periodontitis than in normal controls. Flow cytometry and immunofluorescence showed that overexpression of Akt2 in RAW 264.7 cells induced M1 macrophage polarization and decreased M2 polarization, while knockdown of Akt2 exerted an opposite effect. Furthermore, overexpression of Akt2 activated the JNK pathway and then increased the release of proinflammatory mediators, while knockdown of Akt2 downregulated the above genes accordingly. Importantly, the macrophage polarization and the subsequent alteration of pathway molecules induced by overexpression of Akt2 could be rescued by Akt2 and JNK inhibitors. Epacadostat in vivo Moreover, JNK inhibition could facilitate M2 polarization of macrophages. In a mouse periodontitis model, the novel signaling pathway as well as clinical phenotype was further verified. Inhibition of Akt2 facilitated macrophage M2 polarization and rescued the bone loss due to periodontitis. Collectively, we identified novel Akt2/JNK1/2/c-Jun and Akt2/miR-155-5p/DET1/c-Jun signaling pathways that regulate macrophage polarization and highlight that Akt2 inhibition promotes M2 polarization of macrophages and can be a novel potential candidate in the treatment of periodontitis.DNA methylation is an epigenetic mark that plays an important role in genetic regulation in eukaryotes. Major progress has been made in dissecting the molecular pathways that regulate DNA methylation. Yet, little is known about DNA methylation variation over evolutionary time. Here we present an investigation of the variation of DNA methylation and transposable element (TE) content in species of the filamentous ascomycetes Neurospora. We generated genome-wide DNA methylation data at single-base resolution, together with genomic TE content and gene expression data, of 10 individuals representing five closely related Neurospora species. We found that the methylation levels were low (ranging from 1.3% to 2.5%) and varied among the genomes in a species-specific way. Furthermore, we found that the TEs over 400 bp long were targeted by DNA methylation, and in all genomes, high methylation correlated with low GC, confirming a conserved link between DNA methylation and Repeat Induced Point (RIP) mutations in this group of fungi. Both TE content and DNA methylation pattern showed phylogenetic signal, and the species with the highest TE load (N. crassa) also exhibited the highest methylation level per TE. Our results suggest that DNA methylation is an evolvable trait and indicate that the genomes of Neurospora are shaped by an evolutionary arms race between TEs and host defence.Background Despite the association between chronic pain and post-traumatic stress disorder (PTSD), little is known about the longitudinal course of pain and PTSD during cancer treatment. Objectives We examined the prevalence of PTSD and chronic pain at three time periods in veterans with a diagnosis of cancer, and the relationship between the experience of pain and PTSD. Methods Participants (N = 123) with oral-digestive cancers were recruited from the Veterans Healthcare System (age M = 65.31 and SD = 9.13; 98.4% male) and completed face to face interviews at 6, 12, and 18 months post-diagnosis. Measures included the Post-traumatic Stress Disorder Checklist-Stressor-Specific version (PCL-S), Primary care PTSD (PC-PTSD), and the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Impact Scale. Results About one-third (26.8%) of the sample had chronic pain, defined as elevated pain at two time periods. About one-fifth (20.3%) endorsed symptoms of combat-related PTSD at 6 months, and 22.8% endorsed symptoms of cancer-related PTSD, exceeding a clinical cutoff for older adults (12 months = 21.1%, 18 months = 23.1%). Changes over time were observed for cancer-related PTSD symptom clusters of hyperarousal (F = 3.85 and p = 0.023) and emotional numbing (F = 4.06 and p = 0.018) with a statistically significant quadratic function increasing at 18 months. In logistic regression, individuals with both combat and cancer-related PTSD symptoms at six months had 8.49 times higher odds of experiencing chronic pain (χ2 = 25.91 and p  less then  0.001; R2 = 0.28). Conclusions Persisting pain may be a concern in veterans with cancer. Individuals who have experienced traumatic events with persisting PTSD symptoms may be at elevated risk for chronic pain. Veterans with PTSD symptoms from both cancer and combat are at the highest risk to experience chronic pain.
