Insights into the differential proteome landscape of a newly isolated Paramecium multimicronucleatum in response to cadmium stress.

Employing microbial systems for the bioremediation of contaminated waters represent a potential option, however, limited understanding of the underlying mechanisms hampers the implication of microbial-mediated bioremediation. The omics tools offer a promising approach to explore the molecular basis of the bioremediation process. Here, a mass spectrometry-based quantitative proteome profiling approach was conducted to explore the differential protein levels in cadmium-treated Paramecium multimicronucleatum.

Glucose Deprivation Promotes Cancer Cell Invasion by Varied Expression of EMT Structural Proteins and Regulatory Molecules in MDA-MB-231 Triple-Negative Breast Cancer Cells.

Cancer is one of the biggest leading causes of death worldwide. With increased accumulation of environmental factors like radiation and mutagens, causative mutation in the gene pool is increasing day by day in the human population. Metastasis and its resistance to a wide variety of treatments are the reasons which make cancer difficult to treat.

Identification of Transcription Factors Differentially Expressed under Neuroinflammatory Conditions: Analysis of RNA-Seq Datasets Combined with an Unconventional Exploratory Approach.

Neuroinflammation, the inflammatory process of the brain or peripheral nervous system, is mediated by various chemokines, cytokines, and other secondary messengers. Just like any other physiological process, transcription factors (TFs) lie at the core of neuroinflammatory process too due to their direct effects on the control of gene expression. Although targeted studies are being done on some of the already known TFs involved in neuroinflammation, still the gap exists in profiling the whole repertoire from transcriptomics data which was the main aim of this study.

Glucose Stress Induces Early Onset of Metastasis in Hormone-Sensitive Breast Cancer Cells.

Cell adhesion is the backbone of many events in the cancer cell life cycle, including proliferation, metastasis, migration, invasion and even cell survival. In a tumor, usually the cells in the core have high migratory potential though they constantly suffer from glucose starvation. Our study was aimed at understanding events such as attachment to the surfaces at one site and then mobility to the secondary sites during progression of cancer in the hormone sensitive breast cancer cells MCF7, following their exposure to different concentrations of glucose in the environment.

Bioactivity-Guided Isolation and Identification of Anti-adipogenic Constituents from the n-Butanol Fraction of Cissus quadrangularis.

Obesity is marked by the buildup of fat in adipose tissue that increases body weight and the risk of many associated health problems, including diabetes and cardiovascular disease. Treatment options for obesity are limited, and available medications have many side effects. Thus there is a great need to find alternative medicines for treating obesity.

A computational and bioinformatic analysis of ACE2: an elucidation of its dual role in COVID-19 pathology and finding its associated partners as potential therapeutic targets.

Despite the continued global spread of the current COVID-19 pandemic, the nonavailability of a vaccine or targeted drug against this disease is still prevailing. The most established mechanism of viral entry into the body is considered to be via angiotensin-converting enzyme 2 (ACE2) acting as a receptor for viral spike protein thereby facilitating its entry in the cell. However, ACE2 is also involved in providing the protection from severe pathological changes.

SHISA3, an antagonist of the Wnt/β-catenin signaling, is epigenetically silenced and its ectopic expression suppresses growth in breast cancer.

Breast cancer (BC) is the foremost cause of cancer related deaths in women globally. Currently there is a scarcity of reliable biomarkers for its early stage diagnosis and theranostics monitoring. Altered DNA methylation patterns leading to the silencing of tumor suppressor genes are considered as an important mechanism underlying tumor development and progression in various cancer types, including BC.

Origin, Potential Therapeutic Targets and Treatment for Coronavirus Disease (COVID-19).

Genetic diversity of Paramecium species on the basis of multiple loci analysis and ITS secondary structure models.

Among ciliates, Paramecium has become a privileged model for the study of "species problem" particularly in the case of the "Paramecium aurelia complex" that has been intensely investigated. Despite extensive studies, the taxonomy of Paramecium is still challenging. The major problem is an uneven sampling of Paramecium with relatively few representatives of each species.

Multiple upstream start codons (AUG) in 5' untranslated region enhance translation efficiency of cry2Ac11 without helper protein.

Cry2Ac11, a 65 kDa insecticidal protein produced by Bacillus thuringiensis, shows toxicity against dipteran and lepidopteran larvae. It is encoded by cry2Ac11 gene ( orf3), which is part of an operon comprising orf1, orf2, and orf3. Orf2, a helper protein, helps in proper folding and prevents aberrant aggregation of newly produced molecules.

The DNA sequences coding for MT-TK gene were sequenced and mutations were detected in all participants.

Domain III of Cry1Ac Is Critical to Binding and Toxicity against Soybean Looper (Chrysodeixis includens) but Not to Velvetbean Caterpillar (Anticarsia gemmatalis).

Insecticidal proteins Cry1Ac and Cry2Ac7 from the bacterium (Bt) belong to the three-domain family of Bt toxins. Commercial transgenic soybean hybrids produce Cry1Ac to control the larvae of the soybean looper () and the velvet bean caterpillar (). The specificity of Cry1Ac is determined by loops extending from domain II and regions of domain III in the three-dimensional structure of the toxin.
