ZW10: an emerging orchestrator of organelle dynamics during the cell division cycle.

Zeste white 10 (ZW10) was first identified as a centromere/kinetochore protein encoded by the ZW10 gene in Drosophila. ZW10 guides the spindle assembly checkpoint signaling during mitotic chromosome segregation in metazoans. Recent studies have shown that ZW10 is also involved in membranous organelle interactions during interphase and plays a vital role in membrane transport between the endoplasmic reticulum and Golgi apparatus.

PLK1 phosphorylation of ZW10 guides accurate chromosome segregation in mitosis.

Stable transmission of genetic information during cell division requires faithful chromosome segregation. Mounting evidence has demonstrated that polo-like kinase 1 (PLK1) dynamics at kinetochores control correct kinetochore-microtubule attachments and subsequent silencing of the spindle assembly checkpoint. However, the mechanisms underlying PLK1-mediated silencing of the spindle checkpoint remain elusive.

Clinically proven natural products, vitamins and mineral in boosting up immunity: A comprehensive review.

Background: and Purposes: The terminology "immune boost-up" was the talk of the topic in this Covid-19 pandemic. A significant number of the people took initiative to increase the body's defense capacity through boosting up immunity worldwide. Considering this, the study was designed to explain the natural products, vitamins and mineral that were proved by clinical trail as immunity enhancer.

Genetic association in and genes elevate the risk of prostate cancer.

Background: and are biologically potential genes responsible for prostate cancer.

Aim: We aimed to analyse the expression and association of and genes in prostate cancer.

Subjects And Methods: Web-based bioinformatics tools were used to assess the association of and genes with prostate cancer risks.

Genetic polymorphisms in CDH1 and Exo1 genes elevate the prostate cancer risk in Bangladeshi population.

The polymorphisms of invasion suppressor gene CDH1 and DNA mismatch repair gene Exo1 have been reported to play critical role in the development, tumorigenesis, and progression of several kinds of cancers including prostate cancer. This study was designed to analyze the contribution of single-nucleotide polymorphisms of the CDH1 (-160C/A) and Exo1 (K589E) to prostate cancer susceptibility in Bangladeshi population. The study included 100 prostate cancer cases and age-matched 100 healthy controls.

Evaluation of cytotoxic, analgesic, antidiarrheal and phytochemical properties of Hygrophila spinosa (T. Anders) whole plant.

Background: Synthetic drugs are going to be replaced by plant-derived traditional drugs due to their cost effectiveness, relatively less harmfulness, and efficacy against multidrug resistance organisms. Hygrophila spinosa (Acanthaceae) has been used in a wide range of ailments including flatulence, diarrhea, dysentery, gonorrhea, and menorrhagia. Therefore, we investigated the cytotoxic, antinociceptive, and antidiarrheal effects of H.

Phytopharmacological evaluation of ethanol extract of Sida cordifolia L. roots.

Objective: To investigate the phytochemical screening (group determination) and selected pharmacological activities (antioxidant, antimicrobial and analgesic activity) of the plant Sida cordifolia Linn (S. cordifolia).

Methods: Eighty percent concentrated ethanol extract of the roots was used.

Characteristics of the CD8+ lymphocytosis during primary simian immunodeficiency virus infections.

Objective: To investigate the source of the expanded blood CD8+ subsets during an acute primary simian immunodeficiency virus (SIV) infection of macaques and the potential role of these cells in disease progression.

Design And Methods: The primary CD8+ lymphocytosis, which occurs at 1-2 weeks following infection with SIVsmm/PBj-14, was examined in rhesus and cynomolgus macaques. Extensive subset analysis of the expanded blood CD8+ cell pool in a rhesus macaque was compared phenotypically with those in thymus, lymph nodes, spleen, ileum and lung washouts obtained at necropsy during blood lymphocytosis.

Virus-induced cytokines regulate circulating lymphocyte levels during primary SIV infections.

Decline in blood CD4+ lymphocytes during primary symptomatic infections with HIV is usually attributed to viral killing, and has not been considered in terms of altered lymphocyte migration and sequestration. We therefore sought to examine whether CD4+ cell loss from blood of macaques undergoing an acute primary SIV infection might be due to increased synthesis of cytokines, known to profoundly affect lymphocyte trafficking, rather than to direct lymphocyte destruction by virus. The findings indicate that rapid lymphocyte depletion following acute infection is not selective for CD4+ cells, correlates precisely with increased plasma IFN-gamma and tumor necrosis factor-alpha levels, and is reversible.

Deletion of the nef gene abrogates the ability of SIV smmPBj to induce acutely lethal disease in pigtail macaques.

Simian immunodeficiency virus (SIV) infection in macaque species is typically associated with the development of a progressive immunodeficiency disease, similar to human AIDS, resulting in death of animals in months to years after infection. In contrast, a variant virus, termed SIVsmmPBj, induces an acute disease in macaques, resulting in death in 5 to 14 days after infection. Previously, we have shown that several viral determinants contribute to the pathogenesis of this disease.

Titration and characterization of two rhesus-derived SIVmac challenge stocks.

Simian immunodeficiency virus infection of macaques is a model for human immunodeficiency virus infection of humans. In vivo-titrated stocks of SIV are essential for the utilization of this model for vaccine development. The elicitation of anti-human cell antibodies by some vaccines prepared in human cells and the related protective effects of the vaccine produced in human cells suggest a need for new macaque-derived SIV stocks.
