tion of immuno-markers and molecular subclassification may be helpful for prognostic prediction and selecting an individualized therapeutic strategy for patients with SNSCC.Breast cancer is the major cause of cancer death worldwide in women. Patients with metastasis have poor prognosis and the mechanisms of breast cancer metastasis are not completely understood. Long non-coding RNAs (lncRNAs) have been shown to have crucial roles in breast cancer development and progression. However, the underlying mechanisms by which lncRNA-driven breast cancer metastasis are unknown. The main objective of this paper is to explore a functional lncRNA and its mechanisms in breast cancer. Here we identified a novel lncRNA AC073352.1 that was significantly upregulated in breast cancer tissues and was associated with advanced TNM stages and poor prognosis in breast cancer patients. In addition, AC073352.1 was found to promote the migration and invasion of breast cancer cells in vitro and enhance breast cancer metastasis in vivo. Mechanistically, we elucidated that AC073352.1 interacted with YBX1 and stabilized its protein expression. Knock down of YBX1 reduced breast cancer cell migration and invasion and could partially reverse the stimulative effects of AC073352.1 overexpressed on breast cancer metastasis. Moreover, AC073352.1 might be packaged into exosomes by binding to YBX1 in breast cancer cells resulting in angiogenesis. Collectively, our results demonstrated that AC073352.1 promoted breast cancer metastasis and angiogenesis via binding YBX1, and it could serve as a promising, novel biomarker for prognosis and a therapeutic target in breast cancer.

Pilot study (case series).

The objective of this study was to establish spinal neurophysiological changes following high-frequency transspinal stimulation during robot-assisted step training in individuals with chronic motor complete spinal cord injury (SCI).

University research laboratory (Klab4Recovery).

Four individuals with motor complete SCI received an average of 18 sessions of transspinal stimulation over the thoracolumbar region with a pulse train at 333 Hz during robotic-assisted step training. Each session lasted ~1 h, with an average of 240 stimulations delivered during each training session. Before and after the combined intervention, we evaluated the amplitude modulation of the long-latency tibialis anterior (TA) flexion reflex and transspinal evoked potentials (TEP) recorded from flexors and extensors during assisted stepping, and the TEP recruitment curves at rest.

The long-latency TA flexion reflex was depressed in all phases of the step cycle and the phase-dependent amplitude modulars and extensors in people with motor complete SCI. While both transspinal stimulation and locomotor training may act via similar activity-dependent neuroplasticity mechanisms, combined interventions for rehabilitation of neurological disorders has not been systematically assessed. Our current findings support locomotor training induced neuroplasticity may be augmented with transspinal stimulation.The balanced functionality of cellular proteostatic modules is central to both proteome stability and mitochondrial physiology; thus, the age-related decline of proteostasis also triggers mitochondrial dysfunction, which marks multiple degenerative disorders. Non-functional mitochondria are removed by mitophagy, including Parkin/Pink1-mediated mitophagy. A common feature of neuronal or muscle degenerative diseases, is the accumulation of damaged mitochondria due to disrupted mitophagy rates. Here, we exploit Drosophila as a model organism to investigate the functional role of Parkin/Pink1 in regulating mitophagy and proteostatic responses, as well as in suppressing degenerative phenotypes at the whole organism level. We found that Parkin or Pink1 knock down in young flies modulated proteostatic components in a tissue-dependent manner, increased cell oxidative load, and suppressed mitophagy in neuronal and muscle tissues, causing mitochondrial aggregation and neuromuscular degeneration. Concomitant to Parkin or Pink1 knock down cncC/Nrf2 overexpression, induced the proteostasis network, suppressed oxidative stress, restored mitochondrial function, and elevated mitophagy rates in flies' tissues; it also, largely rescued Parkin or Pink1 knock down-mediated neuromuscular degenerative phenotypes. Our in vivo findings highlight the critical role of the Parkin/Pink1 pathway in mitophagy, and support the therapeutic potency of Nrf2 (a druggable pathway) activation in age-related degenerative diseases.Over the last decade, more than 10 independent SNPs have been discovered to be associated with the risk of renal cell carcinoma among different populations. However, the biological functions of them remain poorly understood. In this study, we performed eQTL analysis, ChIP-PCR, luciferase reporter assay, and Cox regression analysis to identify the functional role and underlying mechanism of rs67311347 in RCC. The ENCORI database, which contains the lncRNA-miRNA-mRNA interactions, was used to explore the possible target miRNA of ENTPD3-AS1. The results showed that the G > A mutation of rs67311347 created a binding motif of ZNF8 and subsequently upregulated ENTPD3-AS1 expression by acting as an enhancer. The TCGA-KIRC and our cohorts both confirmed the downregulation of ENTPD3-AS1 in RCC tissues and demonstrated that increased ENTPD3-AS1 expression was associated with good OS and PFS. Furthermore, ENTPD3-AS1 interacted with miR-155-5p and activated the expression of HIF-1α, which was an important tumor suppressor gene in the development of RCC. The functional experiments revealed that overexpression of ENTPD3-AS1 inhibited cell proliferation in RCC cell lines and the effect could be rescued by knocking down HIF-1α. Our findings reveal that SNP-mediated lncRNA-ENTPD3-AS1 upregulation suppresses renal cell carcinoma via miR-155/HIF-1α signaling.The STING pathway and its induction of autophagy initiate a potent immune defense response upon the recognition of pathogenic DNA. However, this protective response is minimal, as STING activation worsens organ damage, and abnormal autophagy is observed during progressive sepsis. Whether and how the STING pathway affects autophagic flux during sepsis-induced acute lung injury (sALI) are currently unknown. Here, we demonstrate that the level of circulating mtDNA and degree of STING activation are increased in sALI patients. Furthermore, STING activation was found to play a pivotal role in mtDNA-mediated lung injury by evoking an inflammatory storm and disturbing autophagy. Mechanistically, STING activation interferes with lysosomal acidification in an interferon (IFN)-dependent manner without affecting autophagosome biogenesis or fusion, aggravating sepsis. Induction of autophagy or STING deficiency alleviated lung injury. These findings provide new insights into the role of STING in the regulatory mechanisms behind extrapulmonary sALI.The sponge-associated microbial community contributes to the overall health and adaptive capacity of the sponge holobiont. This community is regulated by the environment and the immune system of the host. However, little is known about the effect of environmental stress on the regulation of host immune functions and how this may, in turn, affect sponge-microbe interactions. In this study, we compared the bacterial diversity and immune repertoire of the demosponge, Neopetrosia compacta, and the calcareous sponge, Leucetta chagosensis, under varying levels of acidification and warming stress based on climate scenarios predicted for 2100. Neopetrosia compacta harbors a diverse microbial community and possesses a rich repertoire of scavenger receptors while L. chagosensis has a less diverse microbiome and an expanded range of pattern recognition receptors and immune response-related genes. Upon exposure to RCP 8.5 conditions, the microbiome composition and host transcriptome of N. compacta remained stable, which correlated with high survival (75%). In contrast, tissue necrosis and low survival (25%) of L. chagosensis was accompanied by microbial community shifts and downregulation of host immune-related pathways. Meta-analysis of microbiome diversity and immunological repertoire across poriferan classes further highlights the importance of host-microbe interactions in predicting the fate of sponges under future ocean conditions.BACKGROUND We investigated the impact of collagen usage in colo-colonic anastomoses on intra-abdominal adhesion and anastomosis safety. MATERIAL AND METHODS A total of 30 adult albino Wistar rats (aged 6-8 months) weighing 180-230 g in the laboratory setting were used in this study. Rats were divided into the 3 groups, consisting of 10 rats in each group treated with gentamicin-impregnated collagen, treated with only collagen, and the control group. After 7 days, rats were sacrificed to evaluate adhesion scores and anastomosis bursting pressures. The Evans scoring system was used to rate adhesion levels. HO3867 Bursting pressures were measured using a handheld tension device, and the scores obtained at the moment of tissue dissection were determined as the bursting pressure. RESULTS The mean adhesion scores were 2.86±0.37 in the control group, 1.80±0.91 in the collagen group, and 1.78±0.83 in the gentamicin-impregnated collagen group, with the control group showing significantly higher scores than the other groups (p=0.010 and p=0.011, respectively). The mean bursting pressure levels were 174.29±44.68 mmHg in the control group, 223±38.6 mmHg in collagen group, and 223.33±42 mmHg in the gentamicin-impregnated collagen group, showing that the mean bursting pressure levels were significantly lower in the control group than the other groups (p=0.027 and p=0.029, respectively). CONCLUSIONS This study suggests that colo-colonic anastomosis coverage using materials incorporating collagen alone or gentamicin-impregnated collagen increases the safety of anastomosis and reduces intra-abdominal adhesions.BACKGROUND Anorectal infections occur in 5% to 9% of patients with hematological malignancies, including acute myeloid leukemia, and cause febrile neutropenia and sepsis. Surgical treatments of anorectal abscesses tend to be avoided in patients with leukemia owing to persistent neutropenia and bleeding risks. CASE REPORT A 56-year-old man presented with an ischiorectal abscess. Preoperative laboratory test results revealed leukocytopenia and anemia. He was diagnosed with acute myeloid leukemia. He developed septic shock. Antibiotic treatment was ineffective, and fever persisted. One week later, the abscess was treated by incision and drainage. Two days later, induction chemotherapy was initiated. No pus was drained; cellulitis spread to both buttocks. Pain worsened, and oxycodone was administered. Achievement of complete remission failed. Reinduction therapy was started, followed by fistulotomy of the abscess with extensive debridement of cellulitis on day 6. Granulation was observed on day 17. The patient's fever resolved on day 21. Although hematopoietic recovery was observed, bone marrow examination demonstrated partial remission. Two additional courses of chemotherapy were administered. Abscess recurrence was not observed, even during febrile neutropenia. The surgical wound shrank to a skin defect along the gluteal cleft. He achieved complete remission and was transferred to another hospital, where he underwent 3 allogeneic stem cell transplants. He died of leukemia progression. CONCLUSIONS Surgical treatments can prevent fatal progression of anorectal abscess, even during neutropenia. Incision and drainage are suitable for fluctuant abscesses. For a non-fluctuant abscess aggravated by sepsis and cellulitis, it is worth considering more invasive surgical interventions, including debridement and fistulotomy.
