Transcriptomic analysis of esophageal cancer reveals hub genes and networks involved in cancer progression.

Esophageal carcinoma (ESCA) has a 5-year survival rate of fewer than 20%. The study aimed to identify new predictive biomarkers for ESCA through transcriptomics meta-analysis to address the problems of ineffective cancer therapy, lack of efficient diagnostic tools, and costly screening and contribute to developing more efficient cancer screening and treatments by identifying new marker genes. Nine GEO datasets of three kinds of esophageal carcinoma were analyzed, and 20 differentially expressed genes were detected in carcinogenic pathways.

Exploring existing drugs: proposing potential compounds in the treatment of COVID-19.

The COVID-19 situation had escalated into an unprecedented global crisis in just a few weeks. On the 30 of January 2020, World Health Organization officially declared the COVID-19 epidemic as a public health emergency of international concern. The confirmed cases were reported to exceed 105,856,046 globally, with the death toll of above 2,311,048, according to the dashboard from Johns Hopkins University on the 7 of February, 2021, though the actual figures may be much higher.

Extracellular heat shock proteins and cancer: New perspectives.

Heat shock proteins (HSPs) are a large family of molecular chaperones aberrantly expressed in cancer. The expression of HSPs in tumor cells has been shown to be implicated in the regulation of apoptosis, immune responses, angiogenesis and metastasis. Given that extracellular vesicles (EVs) can serve as potential source for the discovery of clinically useful biomarkers and therapeutic targets, it is of particular interest to study proteomic profiling of HSPs in EVs derived from various biological fluids of cancer patients.

A computational approach to design potential siRNA molecules as a prospective tool for silencing nucleocapsid phosphoprotein and surface glycoprotein gene of SARS-CoV-2.

An outbreak, caused by an RNA virus, SARS-CoV-2 named COVID-19 has become pandemic with a magnitude which is daunting to all public health institutions in the absence of specific antiviral treatment. Surface glycoprotein and nucleocapsid phosphoprotein are two important proteins of this virus facilitating its entry into host cell and genome replication. Small interfering RNA (siRNA) is a prospective tool of the RNA interference (RNAi) pathway for the control of human viral infections by suppressing viral gene expression through hybridization and neutralization of target complementary mRNA.

drug design and molecular docking studies targeting Akt1 (RAC-alpha serine/threonine-protein kinase) and Akt2 (RAC-beta serine/threonine-protein kinase) proteins and investigation of CYP (cytochrome P450) inhibitors against MAOB (monoamine oxidase B) for OSCC (oral squamous cell carcinoma) treatment.

The overexpression of Akt1 (RAC-alpha serine/threonine-protein Kinase) and Akt2 (RAC-beta serine/threonine-protein Kinase) is a hallmark of Oral Squamous Cell Carcinoma (OSCC). Because of the elevated frequency of OSCC occurrence in South Asian countries, novel therapeutic approaches are indispensable. Drugs that inhibit the overexpression of Akt1 and Akt2 proteins in Akt pathway and do not cause reduced expression of MAOB can be leads for OSCC treatment.

Characterization and Analysis of Mammalian AKR7A Gene Promoters: Implications for Transcriptional Regulation.

Aldo-keto reductase (AKR) superfamily is responsible for preventing mammalian cells from the toxic and carcinogenic effect of different genotoxic and non-genotoxic chemicals by reducing them, though the inducibility of these genes are different in different species. The aim of this paper is to compare the gene regulation mechanisms of AKR superfamily genes in different species and to identify the conserved areas, which are responsible for gene regulations in the presence of antioxidant, toxicants, and non-genotoxic carcinogens. At the beginning of the analysis AKR genes found in different species were divided into two groups based on their amino acid sequence similarities.

The Breakthrough of Biosimilars: A Twist in the Narrative of Biological Therapy.

The coming wave of patent expiries of first generation commercialized biotherapeutical drugs has seen the global market open its doors to close copies of these products. These near perfect substitutes, which are termed as "biosimilars", do not need to undergo intense clinical trials for their approval. However, they are mandated to produce identical similarity from their reference biologics in terms of clinical safety and efficacy.

An Empirical Analysis of the Perceived Challenges and Benefits of Introducing Biosimilars in Bangladesh: A Paradigm Shift.

The high demand for and resulting financial success of biopharmaceutical products over the last three decades have seen the door open for close copies of these biological products, also known as biosimilars. This paper seeks to collate all relevant published intelligence with acquired survey data to assess the weight of available evidence that these products hold immense potential for the pharmaceutical industry in terms of their applications and benefits. Biosimilars also pose to be of great promise to the Bangladesh pharmaceutical industry, with the commitment of drastically reducing its dependence on foreign imports of biopharmaceutics to meet local demand.
