E2Fs are genes that regulate DNA synthesis and the cell cycle by encoding a family of transcription factors. Increasing experimental evidence has revealed that E2Fs play key roles in tumor progression in various types of cancer.

We investigated the survival, expression and transcriptional data of E2F1/2/4 in gastric cancer (GC) patients using the immunohistochemistry assay, Kaplan-Meier Plotter, cBioPortal, String, and GEPIA databases. The plasma of GC patients was analyzed using the real-time reverse transcription polymerase chain reaction (RT-PCR) assay. The correlation between E2F1/2/4 expression and clinical features was analyzed using the quartile method. As well, the correlation between E2F1/2/4 and GC immune infiltration was also investigated using the TIMER database. Database of Immune Cell Expression (DICE) was also used to analyze correlations between SOX4 and immune responses.

RT-PCR and tissue immunohistochemistry confirmed that E2F1/2/4 was highly expressed in serum and GC tissue samples of GC patients, the expression of which was not affected by patient age and gender. Also, the survival analysis revealed that low levels of E2F1/2/4 expression were significantly associated with a longer overall survival (OS) in GC patients. E2F1/2/4 was correlated with patient prognosis and immune cell infiltration, including B cells, CD8

T cells, CD4

T cells, macrophages, neutrophils, and DCs in GC. Our findings indicated that E2F1/2/4 could be used as a prognostic biomarker and indicator of immune infiltration in GC.

This study revealed that E2F1/2/4 could be a promising indicator for tumor-associated immune infiltration and prognosis in GC patients.

A growing number of evidence has revealed the vital role of autophagy in pathological processes of cancer, including gastric cancer (GC). However, many previous studies only focused on exploring single pathway or limited genes of interest in GC, which only reflected partial functions of autophagy. The present study aimed to construct an autophagy-related risk signature for GC.

Differentially expressed autophagy-related genes (ARGs) in GC and non-tumor samples were screened through The Cancer Genome Atlas (TCGA) database, followed by bioinformatics analysis using the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) platforms. Prognosis-related ARGs were generated by univariate and multivariate Cox regression test.

A total of seven prognosis-related ARGs (HSPB8, NRG2, GABARAPL1, TMEM74, DLC1, MAP1LC3C and NRG3) were determined to establish a prognostic index (PI) model, which was demonstrated to be an independent prognostic indicator for patients with GC. More importantly, it was successfully validated in an external cohort of patients from the GSE15460 dataset, indicating the useful reproducibility of this signature. In addition, the PI model was associated with immune cell infiltration estimates in GC.

Taken together, the present study suggested that the seven ARGs-related signature could serve as an independent prognostic indicator for patients with GC.

We evaluated the application of enhanced computed tomography (CT) combined with magnetic resonance imaging (MRI) to preoperative diagnosis of thymomas and thymic cysts.

The patients admitted to General Hospital of Tianjin Medical University with anterior mediastinal masses (maximum diameter <5 cm) from 2016 to 2020 were analyzed. In total, 81 patients had been included, including 43 (13 male, 30 female) thymomas (28 cases of myasthenia gravis) and 38 (17 male, 21 female) thymic cysts (2 cases of myasthenia gravis). The median age of the patients with thymomas and thymic cysts was 56 (48-65) and 56.5 (50.8-64) years, respectively. The features of thymomas and thymic cysts revealed on enhanced CT, MRI, and clinically were compared, and we evaluated the diagnostic performance of enhanced CT combined with MRI.

Most thymomas exhibited iso-signal intensity on T1- and T2-weighted imaging (T2WI) and iso- or high-signal intensity on diffusion-weighted imaging. In masses with diameters <3 cm, diffusion-weig MRI is superior to enhanced CT or MRI alone for preoperative differential diagnosis of thymomas and thymic cysts with diameters of less then 5 and less then 3 cm.

Heat shock protein 90 (HSP90) is a molecular chaperone that is responsible for the conformational maintenance of several client proteins that play important roles in DNA damage repair, apoptosis following radiation, and resistance to radiation therapy. DS-2248 (tricyclic pyrazolopyrimidine derivative) is a newly-developed, orally available inhibitor of HSP90 with low adverse effects. We investigated the combined effects of radiation and DS-2248

and

.

SCCVII squamous cell carcinoma cells and tumors transplanted in C3H/HeN mice were used. In vitro combined effects of X-ray radiation and DS-2248 were investigated using a colony assay. Phosphorylated histone H2AX (γH2AX) was quantified after 2-Gy irradiation with or without 24-hour pretreatment with DS-2248. Epinephrine bitartrate research buy The mice bearing SCCVII tumors received oral DS-2248 10 times over 2 weeks and received local irradiation with doses of 1, 2, 3, and 4 Gy delivered 6 times over 2 weeks. Then, tumor volumes were measured.

Radiation plus pretreatment with 50 nM DS-2248 for 24 hours produced synergistic effects on SCCVII cells. γH2AX foci persisted after radiation for longer periods (6 and 24 hours) in DS-2248-treated cells than in control cells. In vivo, the combined effects appeared to be additive when 5 or 10 mg/kg DS-2248 was combined with total radiation doses of 6-18 Gy, but the effect was considered supra-additive when 15 mg/kg of DS-2248 was combined with a total dose of 24 Gy.

The combined effects of DS-2248 and radiation were additive at low drug and radiation doses, but may have been supra-additive at higher doses. Inhibition of slow repair of DNA double strand breaks (i.e., homologous recombination) was considered to contribute to this combined effect.

Invasive adenocarcinoma (IA) manifesting as pure ground-glass nodule is rare and not been well studied. Meanwhile, tumor size is considered as a predictor of invasiveness in lung adenocarcinoma. The present study aimed to investigate the radiological and pathological characteristics as well as prognosis of IA manifesting as pure ground-glass nodule with different sizes.

Patients with solitary pure ground glass nodule (GGN) who underwent resection and were pathologically diagnosed as IA between July 2013 and July 2015 were included. Nodules were divided into four groups according to size A, B, C, and D, corresponding to "≤1 cm," "1-2 cm," "2-3 cm," and ">3 cm," respectively. The correlations and differences in radiological and pathological characteristics as well as prognosis among these groups were analyzed.

The amounts of nodules in groups A, B, C, and D are 17, 148, 78, and 30, respectively. The average diameter of these 273 nodules is 1.9 (1.5-2.4) cm. A large tumor is likely to have low computed culation appearance and exhibit pleural indentation and air bronchogram. Nevertheless, the prognosis is excellent with 100% 5-year disease-free survival regardless of the size and pathological subtype.

The purpose of the present study was to investigate the clinicopathological characteristics and prognostic factors of second primary oral squamous cell carcinoma after radiotherapy for head and neck cancer.

The clinicopathological characteristics of 48 second primary oral squamous cell carcinoma patients with a history of radiotherapy for head and neck cancer were retrospectively analyzed by Kaplan-Meier survival analysis and Cox proportional hazards model, including gender, age, alcohol consumption, smoking, clinical stage, margin status, regional lymph node status, tumor differentiation and treatment mode.

The second primary oral squamous cell carcinoma mostly occurred on the tongue [18/48], buccal [12/48] and gingiva [10/48], and the 3- and 5-year overall survival (OS) was 60.3% and 39.4%, respectively. Margin status and extranodal extension were significantly associated with OS, while only margin status was found to be an independent prognostic factor of OS in the Cox proportional hazards model (P=0.003, HR =3.976, 95% CI 1.596-9.904).

Oral squamous cell carcinoma patients underwent radiotherapy for head and neck cancer show poor survival outcomes. Margin status is an independent prognostic factor of second primary oral squamous cell carcinoma.

This study was designed to explore the prognostic and diagnostic value of Sex-Determining Region Y-Box 9 (SOX9) in cirrhotic hepatocellular carcinoma HCC (CHCC) and noncirrhotic hepatocellular carcinoma (NCHCC).

SOX9 tissue expression was detected using data from The Cancer Genome Atlas (TCGA) database and our cohort. The Kaplan-Meier method was used to analyze differences in survival between high/low SOX9 expression groups. Univariate analysis and multivariate analysis were used to identify independent risk factors associated with overall survival (OS). Receiver operating characteristic (ROC) curve and area under the curve (AUC) were utilized for evaluation of the diagnostic efficacy of SOX9.

SOX9 was found to exhibit differential expression between HCC and adjacent normal tissues but not between CHCC and NCHCC, which was confirmed by RNA sequencing, quantitative real-time polymerase chain reaction and immunohistochemical staining. Kaplan-Meier survival analysis and multivariate analysis revealed that high SOX9 expression was closely related to the OS in NCHCC but not that in CHCC. In CHCC and NCHCC, SOX9 expression was positively associated with serum α-fetoprotein levels. The AUC of SOX9 in differentiating HCC and adjacent normal tissues in CHCC and NCHCC was 0.77 and 0.78, respectively, and no significant difference was found between them.

High SOX9 expression may aid prognostic evaluation in NCHCC but not in CHCC. SOX9 expression was not different between CHCC and NCHCC, but it has reliable and comparable diagnostic value in both CHCC and NCHCC.

Adenosine-to-inosine (A-to-I) RNA editing is one of the most prevalent RNA modifications in the animal kingdom. Since inosine is recognized as guanosines, the A-to-I process mimics A-to-G DNA mutations but can be controlled in a more flexible manner compared to DNA alterations.

We parsed the transcriptomes and translatomes of liver cancer and normal tissues from ten patients. We profiled the landscape of the A-to-I RNA editome in these samples and interrogated whether the A-to-I processes participated in the gene expression regulation in oncogenesis.

Globally, editing activity was enhanced in all tumor samples compared to that in normal samples. Accordingly, expression of the gene encoding the RNA editing enzyme ADAR (adenosine deaminase acting on RNA) was elevated. Two intronic self-editing sites in

mRNAs controlled its splicing pattern and may regulate its translation efficiency (TE). Moreover, the expression of oncogenes was generally upregulated in tumors, whereas tumor suppressor genes (TSG) were downregulated, possibly due to alterations to microRNA binding sites or RNA splicing defects caused by A-to-I editing.
