Although metabolic modulation in the tumor microenvironment (TME) is one of the key mechanisms of cancer immune escape, there is a lack of understanding of the comprehensive immune landscape of the TME and its association with tumor metabolism based on clinical evidence. We aimed to investigate the relationship between the immune landscape in the TME and tumor glucose metabolism in lung adenocarcinoma. Methods: Using RNA sequencing and image data, we developed a transcriptome-based tumor metabolism estimation model...

How to improve the efficacy and reverse the resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), such as erlotinib, remains a major challenge in the targeted therapy of lung adenocarcinoma with EGFR-activating mutation. Phosphoglycerate dehydrogenase (PHGDH) is the key enzyme of de novo serine biosynthesis over-expressed in various types of cancer including lung cancer. Elevated PHGDH expression is correlated with a worse overall survival in clinical lung adenocarcinoma patients...

Lung cancer is a leading cause of cancer-related death among both men and women in the United States, where non-small cell lung cancer accounts for ∼85% of lung cancer. Lung adenocarcinoma (ADC) is the major histologic subtype. The presence of actionable mutations prompts the use of therapies designed to specifically address the deleterious effects of those cancer-driving mutations; these therapies have already shown promise in cases carrying those actionable mutations (∼30%). Innovative therapeutic approaches are needed for the treatment of 70% of patients suffering from lung ADC...

Histone acetylation plays crucial roles in transcriptional regulation and chromatin organization. Viral RNA of the influenza virus interacts with its nucleoprotein (NP), whose function corresponds to that of eukaryotic histones. NP regulates viral replication and has been shown to undergo acetylation by the CREB-binding protein (CBP) from the host. However, whether NP is the target of other host acetyltransferases is unknown. Here, we show that influenza virus NP undergoes acetylation by the two host acetyltransferases GCN5 and P300/CBP-associated factor (PCAF) and that this modification affects viral polymerase activities...

BACKGROUND: Gallbladder cancer is unusually seen but can result in highly mortality rate. It makes challenge to diagnose for clinicians due to present asymptomatic or non-specific clinical presentation including abdominal pain, anorexia. It usually also accompanies with cholelithiasis (incidence is 1-2%) and incidentally detected by radiologic examination such as ultrasound, computed tomography or intra-operative intervention accidentally. Gallbladder cancer results in highly fatal malignancy because it is difficult to early detect...

Germline mutation of BRCA-associated protein-1 has been implicated in the development of tumor predisposition syndrome and high risk for malignant mesothelioma, lung adenocarcinoma, uveal melanoma, and cutaneous melanoma. Here, we present the case of a patient with recurrent metastatic melanoma who was found to have germline BAP1 and somatic BRAF mutation by clinical genomic sequencing. Detection of a germline mutation prompted screening for other cancers and surveillance in family members. Prospective integrative sequencing for pediatric cancer patients may identify pathogenic germline mutations and may improve outcomes and treatment-related morbidity by early diagnosis of malignancy...

miRNAs play important roles in lung adenocarcioma (LADC) progression. We previously found that miR-1290 expression was upregulated in LADC tissue and serum samples from patients with LADC, and correlated with prognosis. However, the biological role of miR-1290 in LADC and mechanism of such role are poorly understood. Here, we found that miR-1290 overexpression promoted LADC cell proliferation, cell cycle progression and invasion, while suppressing cell apoptosis in vitro . Furthermore, miR-1290 promoted tumor growth, invasion and metastasis in vivo ...

TAp73 and p53 are involved in regulating tumor angiogenesis and vasohibin-1 (VASH1) is an anti-angiogenic factor. Whether TAp73 regulates angiogenesis positively or negatively is controversial. The status of P53 may determine the effect of TAp73 on angiogenesis. To the best of our knowledge it has not been previously reported whether TAp73, p53 and VASH1 are coexpressed in lung cancer. We profiled the association between TAp73 and p53 and VASH1 expression in lung adenocarcinoma (LAC) and investigated the function of TAp73 in regulating tumor angiogenesis...

A disintegrin and a metalloprotease (ADAM) 9 is a metzincin cell-surface protease involved in several biological processes such as myogenesis, fertilization, cell migration, inflammatory response, proliferation, and cell-cell interactions. ADAM9 has been found over-expressed in several solid tumors entities such as glioma, melanoma, prostate cancer, pancreatic ductal adenocarcinoma, gastric, breast, lung, and liver cancers. Immunohistochemical analyses highlight ADAM9 expression by actual cancer cells and associate its abundant presence with clinicopathological features such as shortened overall survival, poor tumor grade, de-differentiation, therapy resistance, and metastasis formation...

Hay synthesis of a novel series of symmetrically tetra-substituted thiophenyl zinc(II)phthalocyanines (RS)4 ZnPcs 4a-c was reported. Their novel 4-thiophenyl-phthalonitriles precursors 3(a-c) were synthesized from their substituted thiophenols 2(a-c). They were screened for their in-vitro antitumor activity on Human lung adenocarcinoma (A549), human breast adenocarcinoma (MCF-7) and hepatocellular carcinoma in comparison with healthy normal cells (human fibroblast cells). Preliminary study of the structure-activity relationship showed that electronic factors in the trifluoromethyl moiety that attached to the ZnPc skeleton had a magnificent effect on the antitumor activity of the newly synthesized (RS)4 ZnPcs 4a-c...
