Check point inhibitor anti-PD1 antibody produced some efficacy in Hepatocellular Carcinoma (HCC) patients previously treated with sorafenib. Unfortunately, HCC patients with hepatitis B virus (HBV) infection did not respond as well as uninfected patients. Previously, SMAC mimetics-the antagonist for inhibitor of apoptosis proteins (IAPs) can rapidly reduce serum hepatitis B virus DNA in animal model. APG-1387 is a novel SMAC-mimetic, small molecule inhibitor targeting inhibitor of apoptosis proteins (IAPs)...

Gastric carcinoma is one of the most lethal malignancy at present with leading cause of cancer-related death worldwide. Aquaporins (AQPs) are  family of small, integral membrane proteins, which have been evidenced to play a crucial role in cell migration and proliferation of different cancer cells including gastric cancers. However, the aberrant expression of specific AQPs and its correlation to detect predictive and prognostic significance in gastric cancer remains elusive. In the present study, we comprehensively explored immunohistochemistry based map of protein expression profiles in normal tissues, cancer and cell lines from publicly available Human Protein Atlas database...

Arif Uddin, Supriyo Chakraborty
Lung cancer (LC) is the leading cause of cancer-related deaths all over the world, among both men and women, with an incidence of over 200,000 new cases per year coupled with a very high mortality rate. LC comprises of two major clinicopathological categories: small-cell (SCLC) and nonsmall-cell lung carcinoma (NSCLC). The microRNAs (miRNAs) are small noncoding RNAs, usually 18-25 nucleotides long, which repress protein translation through binding to complementary target mRNAs. The miRNAs regulate many biological processes including cell cycle regulation, cellular growth, proliferation, differentiation, apoptosis, metabolism, neuronal patterning, and aging...

Hidradenoma papilliferum is a rare cutaneous adnexal tumour of middle aged females arising mainly in the apocrine sweat glands of perianal and genital region. Ectopic forms of this entity have been described with majority of them occurring on the head and neck region. We report a case of 16 years young male who presented with two small, well circumscribed, greyish-brown, firm, nodules on his left upper and lower eyelid. A clinical impression of basal cell carcinoma was assumed but on histopathological examination it was diagnosed as hidradenoma papilliferum of eyelid...

OBJECTIVES: While the predictive value of programmed cell death ligand-1 (PD-L1) protein expression for immune checkpoint inhibitor therapy of lung cancer has been extensively studied, the impact of standard platinum-based chemotherapy on PD-L1 or programmed cell death-1 (PD-1) expression is unknown. The aim of this study was to determine the changes in PD-L1 expression of tumor cells (TC) and immune cells (IC), in PD-1 expression of IC, and in the amount of stromal mononuclear cell infiltration after platinum-based chemotherapy in patients with lung cancer...

The cancer stem cell model states that a subset of tumor cells, called "cancer stem cells," can initiate and propagate tumor growth through self-renewal, high proliferative capacity, and their ability to recreate tumor heterogeneity. In basal cell carcinoma (BCC), we have shown that tumor cells that express the cell surface protein CD200 fulfill the cancer stem cell hypothesis. CD200+ CD45- BCC cells represent 0.05-3.96% of all BCC cells and reside in small clusters at the tumor periphery. Using a novel, reproducible in vivo xenograft growth assay, we determined that tumor-initiating cell (TIC) frequencies are approximately 1 per 1...

Although immune checkpoint blockade has shown initial success for various cancers, only a small subset of patients benefits from this therapy. Some chemotherapeutic drugs have been reported to induce antitumor T cell responses, prompting a number of clinical trials on combination chemoimmunotherapy. However, how to achieve potent immune activation with traditional chemotherapeutics in a manner that is safe, effective, and compatible with immunotherapy remains unclear. We show that high-density lipoprotein-mimicking nanodiscs loaded with doxorubicin (DOX), a widely used chemotherapeutic agent, can potentiate immune checkpoint blockade in murine tumor models...

Despite recent advances in screening methods, lung cancer remains the leading cause of cancer-related deaths worldwide. By the time lung cancer becomes symptomatic and patients seek treatment, it is often too advanced for curative measures. Low-dose computed tomography (CT) screening has been shown to reduce mortality in patients at high risk of lung cancer. We present a 66-year-old man with a 50-pack-year smoking history who had a right upper lobe (RUL) pulmonary nodule and left lower lobe (LLL) consolidation on a screening CT...

We have developed the 16F12 mouse monoclonal antibody (mAb) that targets the MISRII receptor expressed by ovarian tumors. Here, we assessed in preclinical models the possibility to use radiolabeled 16F12 in a theranostic approach for small-volume ovarian peritoneal carcinomatosis, for instance after cytoreductive surgery. Methods: DOTA-, DTPA- or DFO-conjugated 16F12 mAb was radiolabeled with beta (177 Lu) or alpha (213 Bi) particle emitters for therapeutic use, and with 89 Zr for positron emission tomography (PET) imaging...

Alpha v beta 6 (αvβ6) integrin is overexpressed by several carcinomas, and thus considered as target for diagnostic imaging and anti-cancer therapies. Recently, we presented SFITGv6 as a novel potential tracer for imaging and targeted therapy of αvβ6 integin-positive carcinomas. Here, we analyzed affinity and specificity of five native αvβ6 integrin-specific binders in comparison to SFITGv6. Methods: Sunflower trypsin inhibitor (SFTI)-1-based peptides containing arginine-glycine-aspartic acid (RGD) motif-spanning octamers of fibronectin (SFFN1), tenascin C (SFTNC), vitronectin (SFVTN), and latency-associated peptides (LAP) 1 (SFLAP1), and 3 (SFLAP3) were synthesized and their binding potential to αvβ6 integrin-expressing head and neck squamous cell carcinoma (HNSCC) cell lines was evaluated...

The display of N-acetylgalactosamine (NAcGal) ligands has shown great potential in improving the targeting of various therapeutic molecules to hepatocellular carcinoma (HCC), a severe disease whose clinical treatment is severely hindered by limitations in delivery of therapeutic cargo. We previously used the display of NAcGal on generation 5 (G5) polyamidoamine (PAMAM) dendrimers connected through a poly(ethylene glycol) (PEG) brush (i.e. G5-cPEG-NAcGal; monoGal) to effectively target hepatic cancer cells and deliver a loaded therapeutic cargo...

BACKGROUND: Immune checkpoint regulators, cytotoxic T lymphocyte antigen 4 (CTLA-4) and the programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) have emerged as promising new targets for cancer therapeutics. While tumor expression of PD-L1 has been shown to have objective responses to anti-PD-L1 immunotherapies, the clinical implications of CTLA-4 expression in tumor cells or immune cells in the tumor microenvironment is still controversial. We investigated the expression of CTLA-4 and PD-L1 in human breast tumors and provided a scoring system for the systematic evaluation of CTLA-4 staining...

Fibroblast activation is associated with tumour progression and implicated in metastasis, but the initial triggering signals required to kick-start this process remain largely unknown. Since small cancerous lesions share limited physical contact with neighboring fibroblasts, we reasoned the first tumour-derived signal for fibroblast activation should be secreted and diffusible. By pulsed metabolic labeling and click-chemistry based affinity enrichment, we sieved through the ductal carcinoma secretome for potential fibroblast activators...

BACKGROUND/AIMS: Lung cancer is one of the most common malignancies in the world. Apoptosis-stimulating protein of p53 (ASPP2), a tumorigenesis related protein, plays a critical role in the initiation and development of various types of cancers. However, the effect of ASPP2 on lung cancer remains unknown. The purpose of this study aims to investigate the mechanism of ASPP2 regulated by miR-21 in lung cancer in vitro and in vivo. METHODS: In the study, migration and invasion assays, apoptosis assay, caspase activity assay, TUNEL staining, real time PCR and western blot were used to investigate the mechanism of ASPP2 regulated by miR-21 in lung cancer in vitro and in vivo...

Small renal masses (SRMs) are increasingly detected incidentally at imaging. They vary widely in histology and aggressiveness, and include benign renal tumors and renal cell carcinomas that can be either indolent or aggressive. Imaging plays a key role in the characterization of these SRMs. While a confident diagnosis can be made in many cases, some renal masses are indeterminate at imaging and can present as diagnostic dilemmas for both the radiologists and the referring clinicians. This article will summarize the current evidence of imaging features that correlate with the biology of small solid renal masses, and discuss key approaches in imaging characterization of these masses using CT and MRI...

Primary neuroendocrine tumours of the cervix are extremely rare, with an incidence of only 0.5-1%; as such, these entities can present a clinical and diagnostic challenge. Small-cell neuroendocrine carcinomas of the cervix are highly aggressive tumours that have a tendency to metastasise. We report a 44-year-old woman who presented to the Gynaecology Clinic of the Employees State Insurance Corporation Medical College & Hospital, Faridabad, India, in 2016 with menorrhagia . Based on a clinical examination, she was provisionally diagnosed with a cervical fibroid...

Epidermal growth factor receptors (EGFRs) and their cytoplasmic tyrosine kinases play significant roles in cell proliferation and signaling. All the members of the EGFR/ErbB family are primary goals for cancer therapy, particularly for tumors of breast, cervix, ovaries, kidney, esophagus, prostate and non-small-cell lung carcinoma and head and neck tumors. However, the therapeutic ability of accessible anti-ErbB agents is limited. Therefore, recognizing EGF analogues or small organic molecules with high affinity for the extracellular domain of the EGFR is a critical target on cancer research...

Cervical cancer is one of the commonest cancers worldwide, especially in developing countries. In early stage disease, a variety of pathological parameters are of prognostic value but currently this does not include tumour grade which, for a number of reasons, is of limited or no value in cervical squamous cell carcinomas. In a recent article in this journal, Jesinghaus and colleagues investigated a novel histopathological grading system based on tumour budding and cell nest size, which has been shown to outperform conventional grading systems for squamous cell carcinoma at several other sites such as lung, oral cavity, and oesophagus in terms of patient prognostication...
