Ionizing radiation has been indispensable to medical diagnosis. In cancer, radiation therapy or radiotherapy (RT) offers patients a better chance of survival. It destroys cancer by depositing high-energy radiation on the cancer tissues, though it may directly damage a few normal cells.J Cell Signal, 2023, Volume 4, Issue 1, p13-20 | DOI: 10.33696/Signaling.4.086
Venetoclax, a small-molecule B-cell lymphoma 2 (BCL-2) inhibitor, selectively eradicates leukemic stem cells (LSCs). While venetoclax has revolutionized the treatment of acute myeloid leukemia (AML), treatment failure and disease relapse are common. Mechanisms underlying venetoclax resistance are surprisingly heterogeneous.J Cell Signal, 2023, Volume 4, Issue 1, p1-12 | DOI: 10.33696/Signaling.4.085
Purinergic P2X7 Receptor as a Potential Targeted Therapy for COVID-19-associated Lung Cancer Progression
Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection is a serious threat to lung cancer patients. Hereby, we hypothesize that Coronavirus disease 2019 (COVID-19) may contribute to lung cancer progression by increasing extracellular adenosine triphosphate (ATP) levels and hyperactivating the purinergic P2X purinoceptor 7 receptor (P2X7R).J Cell Signal, 2023, Volume 4, Issue 1, p21-25 | DOI: 10.33696/Signaling.4.087
HCC is one of the most common malignant tumors. The life and health of humans are gravely threatened by HCC because of its hidden onset, high recurrence rate, poor therapeutic effect, and high mortality. It is essential to explore the particular pathological mechanisms of HCC in order to increase the rate of early diagnosis and enhance patient therapy outcomes.J Cell Signal, 2023, Volume 4, Issue 1, p26-29 | DOI: 10.33696/Signaling.4.088
A Computational Investigation on Rho-related GTP-binding Protein RhoB through Molecular Modeling and Molecular Dynamics Simulation Study
An indispensable member of the Rho family, RhoB is an isoprenylated small GTPases that modulate the cellular cytoskeletal organization. While DNA gets damaged, it takes part in the neoplastic apoptotic mechanism. In this study, we evaluated the structure of Rho-related GTP-binding protein RhoB due to the unavailability of 3D structure in the protein data bank database.J Cell Signal, 2023, Volume 4, Issue 1, p30-48 | DOI: 10.33696/Signaling.4.089
The nature of gene mutations induced by ionizing radiation in germ cells and transmitted to offspring remains one of the most important problems in radiation genetics of higher eukaryotes. The data accumulated in this field were obtained by different authors under different experimental conditions which does not give a complete insight about the nature of radiation-induced inherited mutations at different genome levels (chromosome, gene, DNA).
Karyotypic Profile of Chronic Myeloid Leukemia in Patients Diagnosed at Tertiary Level in Afghanistan
Balanced translocation resulting in fusion of the Abelson gene (ABL1) from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2 is the pathognomonic molecular driver of CML. The resulting BCRABL 1 fusion gene is both the diagnostic as well as therapeutic target of CML. The first agent with tyrosine kinase inhibitor activity that was licenced in 2000 for treatment of CML patients, was Imatinib, gradually followed by multiple agents with higher efficacy.
It is now well accepted that the ionizing radiation-generated reactive oxygen species (ROS), that constitute ~2/3 of the effects of external beam radiation, do not only produce direct tumor cell death, but also affect the surrounding microenvironment. Moreover, this indirect effect of radiation may result in systemic effects, specifically the initiation of an inflammatory response.
While the global COVID-19 pandemic has challenged the entire humanity and health systems, it also triggered researchers to urgently perform clinical trials to assess the safety and efficacy of many agents and modalities to combat COVID-19. As of April 22, over 650 clinical studies have been registered both in USA and internationally. Results from these studies are also coming at a brisk pace in this unprecedented emergency.

This approach drastically changed the way of performing surgical operations, improving patient’s outcome undergoing thoracic surgery.
The variety of methods employed during the fabrication of MONPs can alter the characteristics and control the properties of the obtained nano-oxides. The reaction mechanisms and, therefore, the functionality of nanostructured MOx depend on their composition
Endothelial cells (ECs) are mesodermally-derived modified simple squamous epithelial cells that collectively form the vascular endothelium–the vast living shield that lines the luminal surface of all blood vessels, the lymphatic circuit, and heart. Endothelial cell phenotypes vary among different organs and tissues with regard to specific barrier characteristics, and can be altered by environmental stimuli
The Role of Direct Oral Anticoagulants in Advanced Chronic Kidney Disease – Questions and Future directions
With the advent of the direct oral anticoagulants (DOACs), patients requiring anticoagulation for common conditions such as atrial fibrillation and venous thromboembolism no longer need to worry about dietary restrictions or regular monitoring of the international normalized ratio which complicated warfarin treatment.
VA-Radiation Oncology Quality Surveillance Program: Enhancing Quality Measure Data Capture, Measuring Quality Benchmarks and Ensuring Long Term Sustainability of Quality Improvements in Community Care
High quality cancer care improves patient survival and quality of life. Radiation plays an important role in cancer management, given that over 50% of all cancer patients receive radiation therapy as either a primary treatment or for palliation. Ensuring quality of radiotherapy specifically, is therefore important to achieving optimal patient outcomes.

In the last decade, the study of nanometer-scale particles has grown exponentially worldwide. This growth is due to the broad field of nanostructures applications, which, due to their dimensions in nanometric sizes, have new properties not found in micro and macro scale. These properties result from the increase in the ratio between the surface area and volume, and the nanostructures’ size directly influences these. Tolerance to temperature, variety of colors, changes in chemical reactivity,
