Etoposide‐induced cancer cell death: roles of mitochondrial VDAC1 and calpain, and resistance mechanisms

open access: yesMolecular Oncology, EarlyView.
The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Effective Mixed-Type Tissue Crusher and Simultaneous Isolation of RNA, DNA, and Protein from Solid Tissues Using a TRIzol-Based Method

open access: yesJ
One of the major challenges of studying biomarkers in tumor samples is the low quantity and quality of isolated RNA, DNA, and proteins. Additionally, the extraction methods ideally should obtain macromolecules from the same tumor biopsy, allowing better ...

Dual activity of PNGM-1 pinpoints the evolutionary origin of subclass B3 metallo-β-lactamases: a molecular and evolutionary study

open access: yesEmerging Microbes and Infections, 2019
Resistance to β-lactams is one of the most serious problems associated with Gram-negative infections. β-Lactamases are able to hydrolyze β-lactams such as cephalosporins and/or carbapenems.

Respiratory complex I‐mediated NAD+ regeneration regulates cancer cell proliferation through the transcriptional and translational control of p21Cip1 expression by SIRT3 and SIRT7

open access: yesMolecular Oncology, EarlyView.
NAD+ regeneration by mitochondrial complex I NADH dehydrogenase is important for cancer cell proliferation. Specifically, NAD+ is necessary for the activities of NAD+‐dependent deacetylases SIRT3 and SIRT7, which suppress the expression of p21Cip1 cyclin‐dependent kinase inhibitor, an antiproliferative molecule, at the translational and transcriptional

Drug Resistance in Cancer: An Overview

open access: yesCancers, 2014
Cancers have the ability to develop resistance to traditional therapies, and the increasing prevalence of these drug resistant cancers necessitates further research and treatment development.

DRUG-RESISTANCE OF BACTERIS

open access: yesThe KITAKANTO Medical Journal, 1963
In the field study many types of drug-resistant E. coli, Shigella and Citrobacter were isolated by this laboratory. And seven types of transmissible drug-resistance factor were obtained; R(TC) R(SM), R(CM. TC), R(SM. SA), R(CM. SM SA), R(TC. SM. SA) and R(CM. TC.SM. SA). The R(CM) factor was segregated from (CM.

Drug Resistance in Tuberculosis

open access: yesAnnals of Saudi Medicine, 1990
Resistance to antituberculosis drugs is due to the occurrence of resistant mutants in the bacterial population even before exposure to these drugs. These mutations are chromosomal in origin. Resistance occurs when the bacterial population is large or when drugs are used alone. Potent drugs such as rifampicin, isoniazid and streptomycin are effective in

Analysis of comprehensive genomic profiling of solid tumors with a novel assay for broad analysis in clinical diagnostics

open access: yesMolecular Oncology, EarlyView.
In molecular cancer diagnostics, comprehensive genomic profiling (CGP) is going to replace the small NGS panels since it provides all clinically relevant somatic variants as well as genomic biomarkers with clinical value. Here, we compared two CGP assays and demonstrate that the choice for diagnostic implementation will depend on the specific ...

Enigmatic exosomal connection in lung cancer drug resistance

open access: yesMolecular Therapy: Nucleic Acids
Lung cancer remains a significant global health concern with limited treatment options and poor prognosis, particularly in advanced stages. Small extracellular vesicles such as exosomes, secreted by cancer cells, play a pivotal role in mediating drug ...
