The Clinicopathological and Genetic Characteristics of High-grade Gliomas with Histone H3.3 G34 Mutation in Teenagers and Young adults
Chromatin is composed of nucleosomes, with each nucleosome consisting of an octamer of two copies each of histones H3, H4, H2A, and H2B. Chromatin is critical for the control of transcription, replication, DNA repair and other aspects of genomic stability.J Exp Pathol, 2020, Volume 1, Issue 2, p33-35 | DOI: 10.33696/pathology.1.006
Liposarcoma of Laryngeal Vallecula
Liposarcoma (LS) is the most common soft tissue sarcoma (20% of the tumors in adults). This neoplasm was first described by Virchow in 1857 and has been well documented thereafter. Liposarcoma is a common soft tissue malignant tumor and is often found in the lower extremities and retro peritoneum. Only about 5.6% of liposarcomas are found in the head and neck and most of these tumors arise from the soft tissues of the neck [1-3].J Exp Pathol, 2020, Volume 1, Issue 2, p45-49 | DOI: 10.33696/pathology.1.007

Succinate Accumulation Links Mitochondrial MnSOD Depletion to Aberrant Nuclear DNA Methylation and Altered Cell Fate
Epigenetic processes provide a mechanism for integrating metabolic inputs and translating them into various phenotypic outputs [1,2]. Indeed, epigenetic modifiers often require or are inhibited by key citric acid cycle (CAC) metabolites (e.g. succinate,J Exp Pathol, 2020, Volume 1, Issue 2, p60-70 | DOI: 10.33696/pathology.1.009
Mechanistic and Translational Advances Using iPSC-Derived Blood Cells
The human induced pluripotent stem cell (iPSC) technology was developed more than ten years ago and has provided important tools for the mechanistic and cellular interrogation of many diseases . To generate iPSC lines, somatic cells are reprogrammed into cells resembling embryonic stem cells by the overexpression of key transcription factors.J Exp Pathol, 2020, Volume 1, Issue 2, p36-44 | DOI: 10.33696/pathology.1.010
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).
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.
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.
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.
Circulating Cell-Free RNA: A New Perspective for Endometrial Cancer
In order to implement the knowledge of cancer to monitor its evolution and setting, in the last decade, new minimally invasive and repeatable samples collection have been developed such as liquid biopsy.
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.

The Link of Nutrient Fluxes to Hepatic Insulin Resistance at Gene Expression
Insulin resistance has been studied extensively at systemic, organ, tissue and cellular and molecular levels. Overnutrition plays an essential role in the development of chronic metabolic diseases such as obesity and type 2 diabetes. For subjects without genetic defects, the development of insulin resistance and type 2 diabetes is a graduate process. How the transition from an insulinsensitive state to an insulin-resistant state occurs, and what the roles of nutrients are in the process have not been fully understood. Here, we try to summarize the current understanding of insulin-regulate gene expression in the liver, and describe a phenomenon of hepatic insulin resistance at gene expression (HIRAGE), which may be linked to overnutrition.
