The Many Faces of Sleep Issues in Post-Traumatic Anxiety Condition: A great Up-date in Scientific Characteristics as well as Therapy.
RESULTS Microarray-based analyses revealed that LINC01234 expression was increased in primary EC samples, whereas that of miR-193a-5p was decreased. We found that CCNE1 was a target of miR-193a-5p and that LINC01234, in turn, sponges miR-193a-5p. After treatment with si-LINC01234 or miR-193a-5p mimic, EC cells (Eca-109 and EC9706) exhibited cyclinD1 and Bcl-2 downregulation, and caspase-3, p21, Bax and cleaved caspase-3 upregulation. LINC01234 silencing or miR-193a-5p upregulation resulted in decreased proliferation and colony formation, and increased apoptosis of EC cells. In addition, LINC01234 silencing or miR-193a-5p upregulation resulted in reduced in vivo EC tumor growth and CCNE1 expression in nude mice. CONCLUSIONS We found that silencing of LINC01234 suppresses EC development by inhibiting CCNE1 through competitively binding to miR-193a-5p, which suggests that LINC01234 may represent a novel target for EC therapy.We describe a case of refractory pouchitis successfully treated with tofacitinib. The patient was a 20-year-old woman diagnosed with ulcerative colitis at the age of 14 years. She underwent surgery at the age of 18 years for chronic active inflammation, despite an optimal medication regimen. Ten months after surgery, she was diagnosed with pouchitis. She did not respond to conventional conservative treatment; thus, the case was considered as that of refractory chronic pouchitis. Anti-tumor necrosis factor-α (TNF-α) therapy was administered, which led to some improvement; however, pouchitis recurred. Systemic steroid and vedolizumab were also administered, but the response was unsatisfactory. Therefore, surgery was considered; however, the patient refused to undergo surgery. As identical therapies are recommended for ulcerative colitis and pouchitis, they are considered to have a common etiology. Therefore, we considered tofacitinib therapy in this case. After obtaining the patient's informed consent, tofacitinib treatment was initiated. Acetohydroxamic in vitro The therapy led to improvement in her symptoms as well as in the appearance of the pouch when observed on endoscopy, and surgery was avoided. Thus, tofacitinib may be considered a therapy option for refractory chronic pouchitis.PURPOSE Helicobacter pylori (H. pylori) infection is considered as one of the main cause of gastric cancer. Treatment failure of the infection often occurs due to antibiotic resistance. Herein, we aimed to evaluate the mutations in 23S rRNA gene of H. pylori which are associated with clarithromycin resistance and in rdxA and frxA genes of the bacterium which may be associated with metronidazole resistance, in paraffin-embedded gastric biopsies from patients with gastric adenocarcinoma and gastritis in Tabriz, the northwest of Iran. METHODS In the study, 80 paraffin-embedded tissue sections from 40 gastric cancer and 40 gastritis patients in the Imam Reza hospital, Tabriz, Iran were collected. The existence of ureC gene was verified by PCR method. Genotypical clarithromycin resistance was investigated by real-time PCR method and determination of the melting temperature. PCR reaction and sequencing were used for the evaluation of mutations in rdxA and frxA genes. RESULTS The results of ureC amplification showed that DNA of H. pylori was present in the 82.66% of the obtained DNA samples. About 45.16% of samples were resistant to the clarithromycin and 53.22% of them were resistant to the metronidazole. Based on the results from real-time PCR, the frequency of mutations was as follow A2143G 64.28%, A2142G 44.44% and A2142C 1.11%. The mutations of rdxA gene were 66.66% missense, 30.30% frameshift and 3.03% non-sense. The mutations of frxA gene were 36.36% missense, 54.54% frameshift and non-sense 9.09%. CONCLUSION A2143G mutation is the most frequent mutation among clarithromycin resistant genes in Iran. Also, missense and frameshift mutations are frequent in rdxA and frxA genes. Screening for these mutations could help researchers to investigate the most effective anti-H. pylori antibiotics and to prevent antibiotic resistance.Cancer development is a process of somatic clonal evolution. Darwinian principles of evolution emphasize the interaction between heritable individual variability and selective pressure from the environment. However, the current prevailing concept of cancer evolution mostly focuses on the alterations of genes, signaling, and metabolism inside cells, which underestimates the impact of environmental pressure in selecting the adapted cells. Recently, unsuccessful outcomes and many concerns raised in targeting those alterations inside cells have cast doubt on the current "cell-centric" paradigm of cancer formation, which necessitates a paradigm shift to an outside-in direction that considers environmental changes as a driver in determining the characteristics of selected cells. In the tumor microenvironment, reactive oxygen species (ROS) are one of the most abundant chemical constituents generated by inflammatory and hypoxic conditions. Because of their cytotoxicity when present at high levels, ROS should be the pressure that selects cells with a high capacity for ROS metabolism and antioxidant defense, both of which are referred to as redox metabolism. Cancer genome analyses have found that nuclear factor E2-related factor 2 (NRF2), which plays an indispensable role in redox metabolism, is frequently activated in many types of cancer, particularly lung cancer. This suggests that an ROS-rich microenvironment drives the selection, survival, and growth of cells with high NRF2 activity. Thus, NRF2-driven redox metabolism should be the most crucial part of cancer metabolism, proposing NRF2 inhibitor as an attractive therapeutic target for cancer.Postsynaptic density protein-93 (PSD-93) plays an important role in ischemic brain injury through N-methyl-D-aspartate receptor (NMDAR)-triggered neurotoxicity. GTPase-activating protein for Ras (SynGAP) is a GAP specifically expressed in the central nervous system to regulate nerve development and synaptic plasticity. However, the link between PSD-93 and SynGAP and their role in ischemic brain injury remain elusive. Here, we showed that PSD-93 interacted with SynGAP and mediated SynGAP ubiquitination and degradation following ischemic brain injury. Proteasome inhibitor MG-132 could reverse the decrease of SynGAP protein level in wild-type mice following cerebral ischemia reperfusion through inhibiting SynGAP ubiquitination. Furthermore, NMDA receptor inhibitor MK801 could increase SynGAP protein level in wild-type mice following cerebral ischemia reperfusion. However, in PSD-93 knockout mice, MG-132 or NMDAR inhibitor had no significant effect on SynGAP expression. Both MG-132 and PSD-93 knockout reduced infarct volume and improved neurological deficit in mice at different time points after cerebral ischemia reperfusion.
