This comprehensive review emphasizes the various ways that bioinformatics contribute to biodiversity preservation, agriculture, public health, renewable energy, and environmenta...

Globally, the incidence of cancer is growing rapidly especially among developing nations. Cancer is the second leading cause of mortality worldwide before the age of 70 years. Several statistical techniques have been created and reported for estimating cancer incidence and mortality rates. The standard biomarker for cancer growth and different canc...

Endocrine disruptors are man-made or naturally occurring chemical substances, upon exposure, alter the male reproductive health by interfering with hormonal homeostasis and spermatogenesis. Several studies have supported the hypothesis that a decrease in sperm count over the past few decades is due to exposure to environmental contaminants possessi...

Purpose: Lung cancer is the most commonly diagnosed and leading cause of cancer death worldwide. Imidazo-benzamides are considered to be good anti-cancer agents.

Apoptosis and Male Infertility

Tobacco in its smoke and smokeless form are major risk factors for esophageal squamous cell carcinoma (ESCC). However, molecular alterations associated with smokeless tobacco exposure are poorly understood. In the Indian subcontinent, tobacco is predominantly consumed in chewing form. An understanding of molecular alterations associated with chewin...

Candida tropicalis belongs to the non-albicans group of Candida, and causes epidermal, mucosal, or systemic candidiasis in immunocompromised individuals. Although the prevalence of candidiasis has increased worldwide and non-albicans Candida (NAC) are becoming more significant, there are very few studies that focus on the NAC biology. Proteins and...

Carcinogenic effect of tobacco in oral cancer is through chewing and/or smoking. Significant differences exist in development of oral cancer between tobacco users and non-users. However, molecular alterations induced by different forms of tobacco are yet to be fully elucidated. We developed cellular models of chronic exposure to chewing tobacco and...

Tobacco usage is a known risk factor associated with development of oral cancer. It is mainly consumed in two different forms (smoking and chewing) that vary in their composition and methods of intake. Despite being the leading cause of oral cancer, molecular alterations induced by tobacco are poorly understood. We therefore sought to investigate t...

Smoking is the leading cause of preventable death worldwide. Though cigarette smoke is an established cause of head and neck cancer (including oral cancer), molecular alterations associated with chronic cigarette smoke exposure are poorly studied. To understand the signaling alterations induced by chronic exposure to cigarette smoke, we developed a...

EGFR-based targeted therapies have shown limited success in smokers. Identification of alternate signaling mechanism(s) leading to TKI resistance in smokers is critically important. We observed increased resistance to erlotinib in H358 NSCLC (non-small cell lung carcinoma) cells chronically exposed to cigarette smoke (H358-S) compared to parental c...

The Sertoli cell, the somatic component of seminiferous tubule, provides nutritional support and immunological protection and supports overall growth and division of germ cells. Cytoskeletons, junction proteins, and kinases in Sertoli cells are prime targets for reproductive toxicants and other environmental contaminants. Among the varied targets,...

Background: Dysregulation of miRNAs is associated with the development of non-small cell lung cancer (NSCLC). It is imperative to study the dysregulation of miRNAs by cigarette smoke which will affect their targets, either leading to the overexpression of oncoproteins or downregulation of tumor suppressor proteins. Objective and methods: In this...

Background: Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers with high mortality rate. Cigarette smoke and chewing tobacco are well known risk factors associated with ESCC. However, molecular mechanisms associated with development of ESCC among smokers and chewers are poorly understood. MicroRNAs play an important role i...

Axl-Gas6 signaling plays an important role in numerous cancers. Axl kinase, a member of receptor tyrosine kinase family is activated by different mechanisms with Gas6 as its major activator. Targeting the Axl with inhibitors may block the binding of Gas6 and further hinders the activation of Axl. This in turn inhibits the Axl-Gas6 signaling. Thus,...

Objectives Curcumin has been shown to exhibit anti-neoplastic effects. However, due to its poor bioavailability, the use of curcumin as an anti-cancer drug is limited. Thus, it is necessary to identify molecules as an alternative to curcumin that could serve as anti-cancer targets. In this study, we attempted to understand the underlying curcumin-m...

Epidermal growth factor receptor (EGFR) is overexpressed in 90% of head and neck squamous cell carcinomas (HNSCC). However, most clinical trials with tyrosine kinase inhibitors (TKIs) have shown modest response rates due to development of acquired resistance. We performed whole exome sequencing (WES) of an isogenic pair of erlotinib-sensitive (SCC-...

Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers with high mortality rate. Smoking is one of the established risk factors of ESCC. However, there is limited data on molecular alterations associated with cigarette smoke exposure in esophageal cells. Understanding the effects of cigarette smoke on esophageal squamous epithe...

Tobacco usage is a known risk factor associated with development of oral cancer. It is mainly consumed in two different forms (smoking and chewing) that vary in their composition and methods of intake.

Cellular transformation owing to cigarette smoking is due to chronic exposure and not acute. However, systematic studies to understand the molecular alterations in lung cells due to cigarette smoke are lacking. To understand these molecular alterations induced by chronic cigarette smoke exposure, we carried out tandem mass tag (TMT) based temporal...

Proteomics analysis of chronic cigarette smoke exposure is a rapidly emerging postgenomics research field. While smoking is a major cause of lung cancer, functional studies using proteomics approaches could enrich our mechanistic understanding of the elusive lung cancer global molecular signaling and cigarette smoke relationship. We report in this...

Chronic exposure to cigarette smoke markedly increases the risk for lung cancer. Regulation of gene expression at the post-transcriptional level by miRNAs influences a variety of cancer-related interactomes. Yet, relatively little is known on the effects of long-term cigarette smoke exposure on miRNA expression and gene regulation. NCI-H292 (H292)...

Despite advances in clinical management, 5-year survival rate in patients with late-stage head and neck squamous cell carcinoma (HNSCC) has not improved significantly over the past decade. Targeted therapies have emerged as one of the most promising approaches to treat several malignancies. Though tyrosine phosphorylation accounts for a minority of...

In the last decades, several studies evidenced a decrease in male fertility in developed countries. Although the aetiology of this trend in male reproductive health remains a matter of debate, environmental compounds that predispose to weight gain, namely obesogens, are appointed as contributors because of their action as endocrine disruptors. Obes...

The pineal gland is a neuroendocrine gland located at the center of the brain. It is known to regulate various physiological functions in the body through secretion of the neurohormone melatonin. Comprehensive characterization of the human pineal gland proteome has not been undertaken to date. We employed a high-resolution mass spectrometry-based a...

We investigated the protective role of quercetin and vitamin E on BLCO-induced testicular apoptosis. Experimental rats were divided into four groups of four each. Animals were orally administered 2 ml/kg corn o...

Background The folkloric use of Bonny light crude oil (BLCO) in the treatment of gastrointestinal disorders and as an anti-poison is a generally acceptable practice in the Niger Delta area of Nigeria. The testicular dysfunction induced by BLCO exposure is of public concern with a view to its folkloric usage. The present study investigated the effec...

We hypothesized that de novo variants (DNV) might participate in the genetic determinism of sporadic early-onset Alzheimer disease (EOAD, onset before 65 years). We investigated 14 sporadic EOAD trios first by array-comparative genomic hybridization. Two patients carried a de novo copy number variation (CNV). We then performed whole-exome sequencin...
