C-di-GMP and Its Role in Regulation of Natural Products Production
Among clinical and industrial important microorganisms Streptomyces are the largest source of natural products. But only a fraction of all Biosynthetic Gene Clusters in their genome is active under laboratory conditions. During the last years research has clarified the role of cyclic dimeric 3`-5` guanosine monophosphate, c-di-GMP, as an ubiquitous secondary messenger.J Cell Signal, 2022, Volume 3, Issue 2, p79-90 | DOI: 10.33696/Signaling.3.069
The Role of FCH Domain Only 1 (FCHO1) as an Oncogene in Lung Cancer
Lung cancer is the leading cause of cancer-related death in men and women with a 5-year survival rate of 18%. The PI3K/Akt pathway plays a role in non-small cell lung cancer tumorigenesis and progression. FCH domain only 1(FCHO1) is overexpressed in lung cancer and promotes entry into mitosis and G1/S phase transition, leading to cancer cell growth. Our group has investigated the relationship between FCHO1 and the Akt signaling pathway, which plays an important role in lung cancer growth.J Cell Signal, 2022, Volume 3, Issue 2, p91-95 | DOI: 10.33696/Signaling.3.070

Novel Therapeutic Strategies for Exosome-Related Diseases
Exosomes, a type of extracellular vesicles (EVs), are secreted from cells and taken up again by other cell types. They have attracted attention as new intercellular communication factors involved in various biological processes. Multivesicular bodies (MVBs) are intracellular organelles that are sources of exosomes. Recently, molecular regulatory mechanisms of EVs and MVBs mediated by ubiquitin and ubiquitin-like proteins (UBLs) have been elucidated.J Cell Signal, 2022, Volume 3, Issue 2, p105-109 | DOI: 10.33696/Signaling.3.072
Insights from Natural Product PHGDH Inhibitor Studies
Cancer cells often exhibit a reprogrammed metabolism to accommodate their higher proliferation rates. Serine is a building block for de novo nucleic acids synthesis, and cancer cells typically require more of it. PHGDH is the rate limiting enzyme in human serine synthesis steps and is often highly expressed in cancer.J Cell Signal, 2022, Volume 3, Issue 2, p110-114 | DOI: 10.33696/Signaling.3.073
The Effect of Diet Induced Obesity on Serotonin in Zebrafish
Obesity is a worldwide epidemic and a major risk factor for numerous diseases. The regulation of feeding behavior and body weight depends on a wide range of neuronal pathways influencing satiety and hunger. Serotonin (5-HT) is one of those players identified to have a profound effect on energy homeostasis. The effect of obesity on 5-HT metabolism in the gastrointestinal (GI) tract and its underlying mechanisms still needs to be further elaborated.J Cell Signal, 2022, Volume 3, Issue 2, p115-128 | DOI: 10.33696/Signaling.3.074
The Nature of Radiation-induced Inherited Recessive Gene Mutations in Drosophila Melanogaster
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).
Commentary on NOBOX Mutations in Premature Ovarian Insufficiency
NOBOX is an ovarian specific transcription factor that plays an important role in follicular growth and survival. Nineteen NOBOX variants have been previously associated with premature ovarian insufficiency (POI). Disease severity in patients with heterozygous and homozygous mutations largely overlap however, hampering genotype-phenotype correlations. We recently reported the first case of biallelic truncating mutations (NM_001080413.3 (NOBOX):c.826C>T, p.(Arg276*) and NM_001080413.3(NOBOX):c.1421del, p.(Gly474Alafs*76)) of NOBOX in two Belgian sisters with POI.
Prevalence of Symptom Clusters in Cancer Patients at First Presentation in Palliative Care Clinic as per Different Disease Groups
Cancer has its own disease burden and patients usually suffer from symptom clusters when they are referred for palliative treatment. Identification of symptom cluster trajectories will help clinician to take into account measures that can optimize quality of life of palliative patients. Therefore the aim of this paper is to determine the overall prevalence of symptoms and symptoms clusters in different disease groups according to etiology at the time of first visit to Palliative care clinic by using HIS Palliative First Assessment note indicating Edmonton symptom scale.
Chimeric Antigen Receptor CAR NK Cells Emerging Immunotherapy for the Treatment of Cancer
Although NK cells are recognized as effector lymphocytes of the innate immune system, they also regulate the adaptive immune response by releasing inflammatory cytokines and developing immunological memory. Unlike other lymphocytes such as T or B cells, NK cells do not express rearrangeable, antigen-specific receptors.
Emerging Role of TRPML1 Mucolipin Endolysosomal Channel in Cancer
The transient receptor potential mucolipin 1 (TRPML1) is an endolysosomal channel belonging to the TRP family. Clinically, mutations of TRPML1 have been responsible for a severe lysosomal storage disorder called mucolipidosis type IV.

Five months into the COVID-19 pandemic, the U.S. death toll from the virus has now surpassed 100,000 people. Many more cases remain nationwide, while an unknown number of patients currently harbor the virus asymptomatically. While health officials are now optimistic regarding the decline in prevalence and number of deaths due to COVID-19 and the possibility of a vaccine by the fall, we cannot lose sight of the bigger picture: the next pandemic.
Safety of Using Rituximab Therapy During COVID-19 Pandemic
Rituximab is a chimeric (20% rodent and 80% human) monoclonal antibody that binds to the CD20 antigen present on the cell surface and leads to depletion of mature B-cells [1,2]. It is the first approved monoclonal antibody to be used in the therapy of indolent B-cell non- Hodgkin’s lymphoma and chronic lymphocytic leukemia
Deubiquitinase as Potential Targets for Cancer Immunotherapy
During the last few decades, immunotherapy is considered to be an important approach to help our immune system to fight various kinds of diseases, such as tumor. Sometimes, it works very well for some types of cancers, for example: bladder cancer, colorectal cancer, breast cancer and lymphoma.
The Effect of Glucocorticoids on Angiogenesis in the Treatment of Solid Tumors
Glucocorticoids (GCs) are defined by their role in maintaining glucose homeostasis and natural GCs are a class of corticosteroids secreted by the adrenal cortex. Cortisol is the most important natural GC in humans. Cellular cortisol levels are regulated by the tissue-specific metabolic enzymes 11β-hydroxysteroid dehydrogenase 1 and 2 (11β-HSD 1 and 2); 11β-HSD 1 converts inactive cortisone to active cortisol, while 11β-HSD 2 has the opposite function.

Synthetic Lethal Drug Combinations Targeting Proteasome and Histone Deacetylase Inhibitors in TP53-Mutated Cancers
Tumors harboring mutations in certain oncogenes are often dependent on activation of certain pathways which becomes essential for the survival of the cancer cells. This condition is formally known as synthetic lethality, a state when simultaneous loss of two genes is lethal to a cancer cell, while the loss of the individual genes is not.
Role of the Gut Microbiome in the Modulation of Cancer Immunotherapy Response
The gut microbiome or gut flora is a vast community of microorganisms such as bacteria, viruses, protozoa, and fungi that inhabit the digestive tract of the human and other animals [1,2]. In the human body, bacterial species colonize into the oral cavity, skin, vagina, and placenta, however, the largest population of microorganisms resides in the intestine.
