Nucleolar casein kinase 2 alpha as a prognostic factor in patients with surgically resected early‑stage lung adenocarcinoma.

Lung cancer remains a leading cause of global cancer‑related deaths, therefore the identification of prognostic factors for lung cancer is critical. Casein kinase 2 alpha (CK2α) is one of the driver kinases in various cancers, and it was previously demonstrated that CK2α localization was associated with a poor prognosis in invasive breast cancer. In the present study, the importance of CK2α in the nucleolus was explored as a potential prognostic marker for surgically resected early‑stage lung adenocarcinoma.

[Gut Microbiota as a Potential Biomarker for Immune Checkpoint Inhibitors].

Immune checkpoint inhibitors(ICIs)currently play a predominant role in the standard treatment of non-small cell lung cancer(NSCLC)across all stages. While PD-L1 positivity has traditionally been used as the sole effective biomarker, evidence suggests that certain efficacy exists even in PD-L1-negative lung cancers. Various investigations have been conducted to identify biomarkers predicting the therapeutic efficacy of ICIs, focusing on both tumor-local and host-related factors.

An AsCas12f-based compact genome-editing tool derived by deep mutational scanning and structural analysis.

SpCas9 and AsCas12a are widely utilized as genome-editing tools in human cells. However, their relatively large size poses a limitation for delivery by cargo-size-limited adeno-associated virus (AAV) vectors. The type V-F Cas12f from Acidibacillus sulfuroxidans is exceptionally compact (422 amino acids) and has been harnessed as a compact genome-editing tool.

Analysis of factors related to cognitive impairment in a community-based, complete enumeration survey in Japan: the Nakayama study.

Background: The number of patients with cognitive disorders is rapidly increasing in the world, becoming not only a medical problem, but also a social problem. There have been many reports that various factors are associated with cognitive dysfunction, but the factors have not yet been fully identified. This was a community-based complete enumeration study which aimed to identify risk and protective factors for dementia.

Aberrant Expression of GABA-Related Genes in the Hippocampus of 3xTg-AD Model Mice from the Early to End Stages of Alzheimer's Disease.

Background: We explored the gene expression levels in the brain of 3xTg-AD model mice to elucidate the molecular pathological changes from the early to end stages of Alzheimer's disease (AD).

Objective: We re-analyzed our previously published microarray data obtained from the hippocampus of 3xTg-AD model mice at 12 and 52 weeks of age.

Methods: Functional annotation and network analyses of the up- and downregulated differentially expressed genes (DEGs) in mice aged 12 to 52 weeks were performed.

Gestational exposure to haloperidol changes Cdkn1a and Apaf1 mRNA expressions in mouse hippocampus.

Background: The onset of schizophrenia is associated with both genetic and environmental risks during brain development. Environmental factors during pregnancy can represent risk factors for schizophrenia, and we have previously reported that several microRNA and mRNA expression changes in fetal brains exposed to haloperidol during pregnancy may be related to the onset of this disease. This study aimed to replicate that research and focused on apoptotic-related gene expression changes.

[Clinical Features of Endocrine Disorders with Immune Checkpoint Inhibitor in Patients with Non-Small Cell Lung Cancer].

Immune checkpoint inhibitors(ICIs)could cause immune-related adverse events(irAEs), of which endocrine disorders are relatively common. Symptoms include fatigue, anorexia, and shock, making diagnosis and treatment difficult. This study aimed to analyze the characteristics of patients with non-small cell lung cancer concomitant with endocrine disorders as irAEs.

Wnt/β-Catenin Signaling and Resistance to Immune Checkpoint Inhibitors: From Non-Small-Cell Lung Cancer to Other Cancers.

Lung cancer is the leading cause of cancer-related deaths worldwide. The standard of care for advanced non-small-cell lung cancer (NSCLC) without driver-gene mutations is a combination of an anti-PD-1/PD-L1 antibody and chemotherapy, or an anti-PD-1/PD-L1 antibody and an anti-CTLA-4 antibody with or without chemotherapy. Although there were fewer cases of disease progression in the early stages of combination treatment than with anti-PD-1/PD-L1 antibodies alone, only approximately half of the patients had a long-term response.

Blood expression and methylation status in Alzheimer's disease.

Aim: This study aimed to investigate the expression levels and methylation status of () in the blood of Alzheimer's disease (AD) patients and age- and sex-matched healthy controls.

Methods: Fifty AD outpatients and 50 healthy contorls were enrolled. Blood samples were collected for processing of complementary DNA and genomic DNA.

Ectopic adrenocorticotropic hormone-secreting carcinoid with solitary cryptococcosis in the lungs.

Background: Carcinoid tumors can on rare occasions ectopically produce adrenocorticotropic hormone (ACTH), causing Cushing's syndrome, and patients could become immunocompromised. Care must therefore be taken regarding infectious complications. In particular, ACTH-producing pulmonary carcinoid is not easy to diagnose by itself, and when combined with pulmonary nodules as infectious foci, each is very difficult to diagnose.

[β-Catenin Expression in Non-Small Cell Lung Cancer and Therapeutic Effect of Immune Checkpoint Inhibitors].

Recently, β-catenin mediated immune escape mechanism has been reported in several cancers. We investigated whether β-catenin is associated with resistance to immune checkpoint inhibitor therapy in non-small cell lung cancer. Non-small cell lung cancer patients expressing high levels of β-catenin showed poor progression-free survival and overall survival after single agent anti-PD-1 therapy.

Lung adenocarcinoma coexisting with diffuse idiopathic pulmonary neuroendocrine cell hyperplasia manifesting as multiple pulmonary nodules: A case report.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH), a rare condition, is characterized by pathological proliferation of neuroendocrine cells. Some of them are localized to the airway mucosa, and others locally infiltrate to form tumorlets and nodules. Here, we present a patient with lung adenocarcinoma accompanied by DIPNECH, making the latter difficult to distinguish from multiple pulmonary metastases.

Thoracoscopic resection of posterior mediastinal paraganglioma: perioperative management and surgical tips.

Posterior mediastinal paraganglioma (PM-PGL) is a rare disease that is difficult to diagnose. If PM-PGL is misdiagnosed preoperatively, surgeons may encounter severe tachycardia and hypertension and easy bleeding from the tumor during the operation. Therefore, it is essential to include PGL as a differential diagnosis for mediastinal tumors.

An engineered ACE2 decoy neutralizes the SARS-CoV-2 Omicron variant and confers protection against infection in vivo.

The Omicron (B.1.1.

CTLA-4 Expression in Tumor-infiltrating Lymphocytes Is Irrelevant to PD-L1 Expression in NSCLC.

Background/aim: Treatments containing ipilimumab have shown a good outcome in patients with non-small cell lung cancer (NSCLC) regardless of the PD-L1 tumor proportion score (TPS). However, the association between PD-L1 TPS and the expression of CTLA-4 in tumor-infiltrating lymphocytes is unknown.

Patients And Methods: Fifty-five NSCLC patients who underwent surgery in our hospital were included in this study.

Identification of conserved SARS-CoV-2 spike epitopes that expand public cTfh clonotypes in mild COVID-19 patients.

Adaptive immunity is a fundamental component in controlling COVID-19. In this process, follicular helper T (Tfh) cells are a subset of CD4+ T cells that mediate the production of protective antibodies; however, the SARS-CoV-2 epitopes activating Tfh cells are not well characterized. Here, we identified and crystallized TCRs of public circulating Tfh (cTfh) clonotypes that are expanded in patients who have recovered from mild symptoms.

The clinical significance of tertiary lymphoid structure and its relationship with peripheral blood characteristics in patients with surgically resected non-small cell lung cancer: a single-center, retrospective study.

Introduction: The presence of tertiary lymphoid structure (TLS) in tumor tissues has been reported to be a factor associated with a good prognosis in several types of cancers. However, the relationship between TLS formation and peripheral blood findings remains unclear. The purposes of the study were to evaluate the effect of the presence of TLS on survival and determine the peripheral blood characteristics associated with TLS formation in non-small cell lung cancer (NSCLC) patients.

[Association between Immunotherapy with Immune Checkpoint Inhibitors(Anti-PD-1 Antibodies)and Intestinal Microbiota].

Immune checkpoint inhibitors(ICIs)are playing an increasingly important role in the treatment of cancer. In the field of lung cancer, ICIs are widely administered from primary therapy to maintenance therapy after chemoradiation for non-small cell lung cancer. However, excluding tumor proportion score(TPS)for PD-L1, no other biomarker has been reported to be clinically useful.

Blood CDKN2A Gene Expression in Aging and Neurodegenerative Diseases.

Background: Cyclin-dependent kinase inhibitor 2A (CDKN2A) is an important gene in cellular senescence and aging.

Objective: This study assessed the utility of blood CDKN2A mRNA expression levels and methylation status as a potential biomarker for aging and the pathogenesis of Alzheimer's disease (AD).

Methods: The correlation between CDKN2A mRNA expression levels and age was examined in 45 healthy subjects, after which mRNA expression levels were compared among 46 AD patients, 20 mild cognitive impairment due to AD patients, 21 Parkinson's disease patients, 21 dementia with Lewy bodies patients, and 55 older healthy controls.

A patient with ALK-positive lung adenocarcinoma who survived alectinib-refractory postoperative recurrence for 4 years by switching to ceritinib.

Echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) rearrangements are found in ~ 5% of patients with non-small cell lung cancer (NSCLC). Several tyrosine kinase inhibitors (TKIs) have been developed for treatment of so-called ALK-positive NSCLC. In cases of tumor progression during treatment with second-generation ALK-TKIs, such as alectinib, brigatinib, or ceritinib, National Comprehensive Cancer Network guidelines propose a switch to lorlatinib, a third-generation ALK-TKI, or to cytotoxic chemotherapy.

CLDN15 is a novel diagnostic marker for malignant pleural mesothelioma.

Malignant mesothelioma is a cancer with a poor survival rate. It is difficult to diagnose mesotheliomas because they show a variety of histological patterns similar to those of various other cancers. However, since currently used positive markers for mesotheliomas may show false positives or false negatives, a novel mesothelial positive marker is required.
