Predicting exploratory thoracotomy in non-small cell lung cancer: a computed tomography based nomogram approach.

Purpose: Non-small cell lung cancer (NSCLC) constitutes a substantial global health challenge, with surgical resection serving as a principal therapeutic approach. Nevertheless, the frequency of exploratory thoracotomy without en-bloc resection remains significant, particularly in advanced-stage cases, thereby adversely affecting prognosis. This study aims to predict risk scores for exploratory thoracotomy and analyze postoperative survival in patients with central NSCLC, utilizing CT (computed tomography) imaging subsequent to neoadjuvant therapy.

NPC1L1 on pancreatic adenocarcinoma cell functions as a two-pronged checkpoint against antitumor activity.

Pancreatic adenocarcinoma (PAAD) is a highly lethal malignancy with an immunosuppressive microenvironment and a limited immunotherapy response Cholesterol is necessary for rapid growth of cancer cells, and cholesterol metabolism reprogramming is a hallmark of PAAD. How PAAD cells initiate cholesterol reprogramming to sustain their growth demand and suppressive immunomicroenvironment remains elusive. In this study, we for the first time revealed that PAAD cells overcome cholesterol shortage and immune surveillance via ectopically overexpressing NPC1L1, a cholesterol transporter but function as a two-pronged checkpoint, which not only directly suppresses TCR activation of CD8T cells but also hijacks the intracellular cholesterol from CD8T cells.

BCAR1 facilitates the survival of lung adenocarcinoma cells by augmenting the unfolded protein response, autophagy, and the formation of vasculogenic mimicry.

Background: Our objective was to elucidate the pivotal roles of BCAR1 in unfolded protein response (UPR), autophagy and vasculogenic mimicry (VM) formation, processes that essential for the metastasis of lung adenocarcinoma (LUAD) cells.

Methods: The morphological assessment of endoplasmic reticulum (ER) status and autolysosomes in H1975 and H1299 LUAD cells following BCAR1 knockout (KO) was conducted using transmission electron microscope. The expression of markers and cellular functions related to the UPR, autophagy, and VM formation were examined in LUAD cells tissues.

However, no evidence exists to direct clinical decision-making regarding the choice of operative and nonoperative management. This study aimed to determine the clinical efficacy of different therapeutic strategies in both general and stratified patients.

E3 ubiquitin ligase TRIM21 targets TIF1γ to regulate β-catenin signaling in glioblastoma.

Elucidation of the mechanism of ubiquitation has led to novel ways to treat glioblastoma (GBM). A tripartite motif (TRIM) protein mediates a reversible, stringent ubiquitation which is closely related to glioma malignancy. This study intends to screen the most vital and abnormal regulating component of the tripartite motif protein and to explore its underlying mechanisms.

Research on skeletal muscle impact injury using a new rat model from a bioimpact machine.

: Skeletal muscle impact injury occurs frequently during sports, falls, and road traffic accidents. From the reported studies on skeletal muscle injury, it is difficult to determine the injury parameters. Therefore, we developed a new model of gastrocnemius impact injury in rats with a bioimpact machine, with which the experimental operation could be conducted in feasibility from the recorded parameters.

Inhibition of APE1 Expression Enhances the Antitumor Activity of Olaparib in Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer that is prone to recurrence and metastasis. Because of the lack of expression of estrogen receptor (ER) and progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) in TNBC, treatment methods are greatly limited. In this study, the proliferation inhibition and apoptosis-inducing effects of PARP1 inhibitors in TNBC breast cancer cells and in vivo xenograft animal models were examined to investigate the molecular role of APE1 in PARP1-targeted therapy.

Dry eye symptoms in interferon regulatory factor 3-deficient mice due to herpes simplex virus infection in harderian gland and lacrimal gland.

Purpose: Dry eye syndrome (DES) is a multifactorial ocular disorder. The possible pathogens and pathogenic mechanisms for virus-related dry eye disease are largely unknown. The current study aimed to provide evidence for mechanisms contributing to DES induced by herpes simplex virus (HSV) infection in the harderian gland (HG) and lacrimal gland (LG).

A Clinical Diagnostic Study: Fibulin-2 is a Novel Promising Biomarker for Predicting Infection.

Introduction: Infection remains a major cause of morbidity and mortality in hospital. As uncontrolled early infection may develop into systemic infection and eventually progress to sepsis, it is important to address infection at an early stage. Furthermore, early detection and prompt diagnosis of infection are the basis of clinical intervention.

The development and progress of nanomedicine for esophageal cancer diagnosis and treatment.

Esophageal cancer (EC) is a common gastrointestinal malignancy with poor prognosis and high mortality. Although combined therapeutic strategies have been developed, the 5-year survival rate of patients with EC remains relatively poor. Conventional anti-cancer drug delivery techniques have some shortcomings, such as nontargeted delivery and nonspecific toxicity.

Gut Microbiota for Esophageal Cancer: Role in Carcinogenesis and Clinical Implications.

Esophageal cancer (EC) is a common malignant tumor of the upper digestive tract. The microbiota in the digestive tract epithelium comprises a large number of microorganisms that adapt to the immune defense and interact with the host to form symbiotic networks, which affect many physiological processes such as metabolism, tissue development, and immune response. Reports indicate that there are microbial compositional changes in patients with EC, which provides an important opportunity to advance clinical applications based on findings on the gut microbiota.

Pulmonary Sclerosing Pneumocytoma (PSP) is considered as a benign tumor, although a few cases have been reported to have multiple lesions, recurrence, and even regional lymph nodes (LNs) metastasis. Here, we report a case of PSP with atypical histologic features and malignant biological behavior, and explore its molecular genetic changes. The 23-year-old male showed a 6.

BCAR1 plays critical roles in the formation and immunoevasion of invasive circulating tumor cells in lung adenocarcinoma.

We investigated the roles of breast cancer anti-estrogen resistance 1 (BCAR1/p130Cas) in the formation and immunoevasion of invasive circulating tumor cells (CTCs) in lung adenocarcinoma (LUAD). Biomarkers of CTCs including BCAR1 and CD274, were evaluated by the CanPatrol method. Proteomics analysis of LUAD cells and exosomes after BCAR1 overexpression (BCAR1-OE) was performed by mass spectrometry.

Inhibiting the redox function of APE1 suppresses cervical cancer metastasis via disengagement of ZEB1 from E-cadherin in EMT.

Background: Metastasis is a major challenge in cervical cancer treatment. Previous studies have shown that the dual functional protein apurinic/apyrimidinic endonuclease 1 (APE1) promotes tumor metastasis and is overexpressed in cervical cancer. However, the biological role and mechanism of APE1 in cervical cancer metastasis have rarely been studied.

Advances in Drug Resistance of Esophageal Cancer: From the Perspective of Tumor Microenvironment.

Drug resistance represents the major obstacle to get the maximum therapeutic benefit for patients with esophageal cancer since numerous patients are inherently or adaptively resistant to therapeutic agents. Notably, increasing evidence has demonstrated that drug resistance is closely related to the crosstalk between tumor cells and the tumor microenvironment (TME). TME is a dynamic and ever-changing complex biological network whose diverse cellular and non-cellular components influence hallmarks and fates of tumor cells from the outside, and this is responsible for the development of resistance to conventional therapeutic agents to some extent.

Mechanisms of Pharmaceutical Therapy and Drug Resistance in Esophageal Cancer.

Pharmaceutical therapies are essential for esophageal cancer (EC). For the advanced EC, the neoadjuvant therapy regimen, including chemotherapy plus radiotherapy and/or immunotherapy, is effective to achieve clinical benefit, even pathological complete response. For the unresectable, recurrent, and metastatic EC, the pharmaceutical therapy is the limited effective regimen to alleviate the disease and prolong the progression-free survival and overall survival.

U three protein 14a (UTP14A) promotes tumour proliferation and metastasis via the PERK/eIF2a/GRP78 signalling pathway in oesophageal squamous cell carcinoma.

Metastasis and malignant proliferation are major obstacles to the treatment of oesophageal squamous cell carcinoma (ESCC), and UTP14A is associated with poor prognosis in ESCC. However, its mechanisms have not been fully elucidated. The TCGA and GEO databases were used to identify candidate target genes and possible downstream targets.

Simultaneous expression of TTF1 and GATA3 in a lung biopsy sample: confusion in diagnostic pathology.

Background: In daily work, pathologists often use TTF1 and GATA3 in the differential diagnosis of primary lung adenocarcinoma (TTF1+ GATA3-) and metastatic bladder cancer (or breast cancer) (TTF1- GATA3+). However, we encountered a small lung biopsy sample of TTF1+ GATA3+ (clinically suggesting both lung and bladder occupancy), and the dyeing results caused us great confusion; thus, we intended to determine the expressions of TTF1 and GATA3 in lung and bladder cancer by expanding the sample.

Methods: The study included a complete case report and the tissue microarrays including pulmonary squamous cell carcinomas (n = 55), lung adenocarcinomas (n = 47), high-grade (n = 68) and low-grade (n = 43) urothelial carcinomas of the bladder.

Epigenetic Inactivation of SOX30 Is Associated with Male Infertility and Offers a Therapy Target for Non-obstructive Azoospermia.

Non-obstructive azoospermia (NOA) is the most severe form of male infertility. However, the etiology of NOA is largely unknown, resulting in a lack of clinical treatments. Here, we performed a comparative genome-wide profiling of DNA methylation and identified SOX30 as the most notably hyper-methylated gene at promoter in testicular tissues from NOA patients.

Overexpression of U three protein 14a (UTP14a) is associated with poor prognosis of esophageal squamous cell carcinoma.

Background: Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive and lethal cancers lacking valid prognostic biomarkers. As an essential component of a large ribonucleoprotein complex, U Three Protein 14a (UTP14a) might play important roles in human tumorigenesis. However, the clinical significance and functions of UTP14a in ESCC still remain unclear.
