Dietary methionine supplementation promotes mice hematopoiesis after irradiation.

Background: With the increasing risk of nuclear exposure, more attention has been paid to the prevention and treatment of acute radiation syndrome (ARS). Although amino acids are key nutrients involved in hematopoietic regulation, the impacts of amino acids on bone marrow hematopoiesis following irradiation and the associated mechanisms have not been fully elucidated. Hence, it is of paramount importance to study the changes in amino acid metabolism after irradiation and their effects on hematopoiesis as well as the related mechanisms.

Integrated whole-exome and bulk transcriptome sequencing delineates the dynamic evolution from preneoplasia to invasive lung adenocarcinoma featured with ground-glass nodules.

Objective: The genomic and molecular ecology involved in the stepwise continuum progression of lung adenocarcinoma (LUAD) from adenocarcinoma in situ (AIS) to minimally invasive adenocarcinoma (MIA) and subsequent invasive adenocarcinoma (IAC) remains unclear and requires further elucidation. We aimed to characterize gene mutations and expression landscapes, and explore the association between differentially expressed genes (DEGs) and significantly mutated genes (SMGs) during the dynamic evolution from AIS to IAC.

Methods: Thirty-five patients with ground-glass nodules (GGNs) lung adenocarcinomas were enrolled.

A novel enemy of cancer: recent investigations into protozoan anti-tumor properties.

Cancer remains a significant global health issue, despite advances in screening and treatment. While existing tumor treatment protocols such as surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy have proven effective in enhancing the prognosis for some patients, these treatments do not benefit all patients. Consequently, certain types of cancer continue to exhibit a relatively low 5-year survival rate.

Ivermectin induces nonprotective autophagy by downregulating PAK1 and apoptosis in lung adenocarcinoma cells.

Introduction: LUAD (Lung adenocarcinoma), the most common subtype of lung carcinoma and one of the highest incidences and mortality cancers in the world remains still a substantial treatment challenge. Ivermectin, an avermectin derivative, has been traditionally used as an antiparasitic agent in human and veterinary medicine practice during the last few decades. Though ivermectin has been shown to be effective against a variety of cancers, however, there is few available data reporting the antitumor effects of ivermectin in LUAD.

Postoperative radiotherapy for completely resected thymoma: Differing roles in masaoka stage II and stage III disease.

Methods: Recorded cases of thymoma at Xinqiao Hospital were retrospectively analyzed from 1991 to 2019.

Circumsporozoite Protein Enhances the Efficacy of Gefitinib in Lung Adenocarcinoma Cells by Inhibiting Autophagy Proteasomal Degradation of LC3B.

Almost all lung adenocarcinoma (LUAD) patients with EGFR mutant will develop resistance to EGFR-TKIs, which limit the long-term clinical application of these agents. Accumulating evidence shows one of the main reasons for resistance to EGFR-TKIs is induction of autophagy in tumor cells. Our previous study found that circumsporozoite protein (CSP) in can suppress autophagy in host hepatocytes.

CWHM-1008 is a novel class of antimalarial drug; however, the inhibitory impact of CWHM-1008 on lung adenocarcinoma (LUAD) cells remains unclear. This study aimed to explore the anticancer effect and underlying mechanisms of CWHM-1008 on LUAD cells in vitro and in vivo.

REPORT- Clinical outcomes of using second - versus first-Generation EGFR-tkis for the First-Line treatment of advanced NSCLC patients with EGFR mutations: A meta-analysis.

First-generation EGFR-TKIs (gefitinib/erlotinib) and second-generation EGFR-TKI (afatinib) have become the current first-line treatments for EGFR-mutated non-small cell lung cancer (NSCLC), however, the effects of using second-generation EGFR-TKIs compared to those of using first-generation EGFR-TKIs as a first-line treatment for NSCLC patients with EGFR mutations remain unknown. We conducted this meta-analysis based on 4 retrospective and 2 randomized controlled studies published between 2016 and 2018. We surveyed the effectiveness of afatinib/dacomitinib and gefitinib/erlotinib as first-line treatments for stage III-IV EGFR-mutated NSCLC patients.

A Noninvasive Multianalytical Approach for Lung Cancer Diagnosis of Patients with Pulmonary Nodules.

Addressing the high false-positive rate of conventional low-dose computed tomography (LDCT) for lung cancer diagnosis, the efficacy of incorporating blood-based noninvasive testing for assisting practicing clinician's decision making in diagnosis of pulmonary nodules (PNs) is investigated. In this prospective observative study, next generation sequencing- (NGS-) based cell-free DNA (cfDNA) mutation profiling, NGS-based cfDNA methylation profiling, and blood-based protein cancer biomarker testing are performed for patients with PNs, who are diagnosed as high-risk patients through LDCT and subsequently undergo surgical resections, with tissue sections pathologically examined and classified. Using pathological classification as the gold standard, statistical and machine learning methods are used to select molecular markers associated with tissue's malignant classification based on a 98-patient discovery cohort (28 benign and 70 malignant), and to construct an integrative multianalytical model for tissue malignancy prediction.

Repositioning of Antiparasitic Drugs for Tumor Treatment.

Drug repositioning is a strategy for identifying new antitumor drugs; this strategy allows existing and approved clinical drugs to be innovatively repurposed to treat tumors. Based on the similarities between parasitic diseases and cancer, recent studies aimed to investigate the efficacy of existing antiparasitic drugs in cancer. In this review, we selected two antihelminthic drugs (macrolides and benzimidazoles) and two antiprotozoal drugs (artemisinin and its derivatives, and quinolines) and summarized the research progresses made to date on the role of these drugs in cancer.

Moesin as a prognostic indicator of lung adenocarcinoma improves prognosis by enhancing immune lymphocyte infiltration.

Background: Ezrin-radixin-moesin (ERM) have been explored in many cancer processes. Moesin, as its component, has also been found to play an important role in the prognosis of cancer patients, tumor metastasis, drug resistance, and others. Especially in regulating the immunity, but most results came from direct studies on immune cells, there is no clear conclusion on whether moesin has similar effects in tumor cells.

Artesunate inhibits epithelial-mesenchymal transition in non-small-cell lung cancer (NSCLC) cells by down-regulating the expression of .

In recent years, more and more studies have shown that antiparasitic drugs can affect a variety of biological processes of tumor cells and exhibit a potential anti-tumor activity. Although artesunate (ART), a strong bioactive derivative of artemisinin and widely used clinically against malaria, was found to have an inhibitory effect on tumor cells, it is still unclear whether ART could regulate the tumor malignancy of non-small-cell lung cancer (NSCLC) cells. In this study, we aimed to investigate the effect of ART on migration capacities in NSCLC cell lines of A549 and H1975.

Objective: To analyze the clinical value and molecular mechanism of in non-small cell lung cancer (NSCLC).

Safety and efficacy of INTRABEAM intraoperative radiotherapy for invasive thymoma.

Intraoperative radiotherapy (IORT) has been used to treat different residual solid tumors after tumor removal and has shown many advantages over other treatment methods. However, the use of IORT for invasive thymoma has not been reported. Therefore, in this study, we tried to determine the safety and efficacy of INTRABEAM IORT for the treatment of invasive thymoma.

Dichloroacetate enhances the antitumor efficacy of chemotherapeutic agents via inhibiting autophagy in non-small-cell lung cancer.

Background: Chemotherapy is still the primary adjuvant strategy of cancer therapy; however, the emergence of multi-drug resistance has been a cause for concern. Autophagy has been demonstrated to have a protective role against chemotherapeutic drugs in cancer cells, and autophagy inhibition is generally considered to be a promising therapeutic strategy. However, the paucity of effective and specific autophagy inhibitors limits its application.

Plasmodium circumsporozoite protein suppresses the growth of A549 cells via inhibiting nuclear transcription factor κB.

Blocking the activation of nuclear factor κB (NF-κB) is a promising strategy for the treatment of non-small cell lung cancer. The circumsporozoite protein (CSP), a key component of the sporozoite stage of the malaria parasite, was previously reported to block NF-κB activation in hepatocytes. Therefore, in the present study, the effect of CSP on the growth of the human lung cancer cell line, A549, was investigated.

SGEF is a potential prognostic and therapeutic target for lung adenocarcinoma.

Background: SH3-containing guanine nucleotide exchange factor (SGEF), a RhoG-specific guanine nucleotide exchange factor (GEF), was consider as a key signal that determines cancer cell invasion. Although SGEF has been considered to highly express in glioma and prostate cancer. However, it is not well illustrated in LAC.

Anastomotic reinforcement with omentoplasty reduces anastomotic leakage for minimally invasive esophagectomy with cervical anastomosis.

Purpose: Anastomotic leakage is the most feared postoperative complication after esophagectomy. Omentoplasty, wrapping the omentum around the alimentary tract anastomosis, is thought to decrease the anastomotic leakage rate. The purpose of this clinical study is to investigate the use of omentoplasty to reinforce cervical esophagogastrostomy after minimally invasive esophagectomy (MIE).

Clinical outcomes of WBRT plus EGFR-TKIs versus WBRT or TKIs alone for the treatment of cerebral metastatic NSCLC patients: a meta-analysis.

Whether WBRT plus EGFR-TKIs has a greater survival benefit than EGFR-TKIs alone or WBRT alone remains controversial in NSCLC patients with multiple brain metastases. To rectify this, we conducted a systematic meta-analysis based on 9 retrospective studies and 1 randomized controlled study published between 2012 and 2016, comprising 1041 patients. Five studies were included in the comparison of WBRT plus EGFR-TKIs and EGFR-TKIs alone.

Segmentectomy versus wedge resection for the treatment of high-risk operable patients with stage I non-small cell lung cancer: a meta-analysis.
