Chromosome 7 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 7, one copy inherited from each parent, form one of the pairs. Chromosome 7 spans about 159 million DNA building blocks (base pairs) and represents more than 5 percent of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 7 likely contains about 1,150 genes.

Genes on chromosome 7 are among the estimated 20,000 to 25,000 total genes in the human genome.

Researchers identify genes that make Staphyloccocus bacteria resistant to treatment

A Rutgers-led team has discovered two genes that make some strains of harmful Staphyloccocus bacteria resistant to treatment by copper, a potent and frequently used antibacterial agent.

Researchers reveal novel computational tool used to analyze genetic variation

The field of genetic sequencing has undergone a dramatic revolution over the past 20 years. In 2001 the first copy of the three billion base pairs that assemble the human genome was published.

Zebrafish offers clue to alleviate gastrointestinal distress related to autism

University of Miami researchers have discovered a clue in the humble zebrafish's digestive tract that, one day, could help people on the autism spectrum alleviate one of the most common yet least studied symptoms of their disorder: gastrointestinal distress.

Cannabinoid receptor type 1 appears to be potential target to treat Down syndrome

A study by the Neuropharmacology Laboratory-NeuroPhar of the Department of Experimental and Health Sciences at UPF reveals the involvement of the endocannabinoid system in cognitive disorders in mouse models of Down syndrome.

Study: BldC protein in Streptomyces acts as ‘brake’ to control timing of sporulation

Streptomyces are soil-dwelling bacteria that produce approximately two-thirds of the antibiotics in current clinical use.

Large genetic analysis of impulsiveness reveals links with psychiatric disorders

Impulsiveness and substance use share a genetic basis, according to genome-wide association studies published in JNeurosci by academic and industry researchers.

Study sheds light on the genetic causes of tumors in salivary glands

Acinic cell carcinoma is the third most common malignant form of salivary gland cancer. These tumors are similar to normal salivary gland tissue and occur most frequently in the parotid gland.

Researchers discover how transcription factors find specific loci within DNA

Bioengineering experts have discovered that transcription factors which bind non-specifically to mitotic chromosomes are more efficient at finding their binding site within DNA during interphase.

Study shows that aging and chronic diseases share common genetic factors

The global population aged 60 or over is growing faster than all younger age groups and faces the tide of chronic diseases threatening their quality of life and posing challenges to healthcare and economy systems.

Big data opens door for characterizing immunity-related genome in Japanese population

Although different genes are distributed widely across chromosomes, many genes related to the immune system are clustered together on human chromosome 6, in a segment called the major histocompatibility complex (MHC) region.

RNA-induced gene fusion can occur in mammalian cells, reveals study

A fusion gene is a new gene made by joining parts of two different genes. The current thought is that fusion genes can happen in cells with unstable genome when part of the DNA from one chromosome moves to another chromosome.

Nine early career scientists named 2019 recipients of the Damon Runyon-Rachleff Innovation Award

The Damon Runyon Cancer Research Foundation announced that nine scientists with novel approaches to fighting cancer have been named 2019 recipients of the Damon Runyon-Rachleff Innovation Award.

Novel therapeutic approach for treatment of leukemia

The BCR/ABL gene, which does not occur among healthy people, has been shown to be a causative agent in the pathogenesis of B-cell acute lymphocytic leukemia.

Researchers uncover new role of heterochromatin in maintaining chromosomal integrity

Although many people are aware that chromosomal damage and shortening contribute to the aging process, understanding how chromosomal defects occur is about more than just finding a way to turn back the clock. Large changes in the structure of chromosomes, known as gross chromosomal rearrangements, can result in cell death or genetic diseases such as cancer.

Cellular recycling process may prevent cancer initiation, finds study

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA.

Study sheds new light on male infertility

Hope has emerged for infertile men as scientists at Newcastle University have understood the importance of a gene in regulating the production of fully-functioning sperm.

New research focuses on noise sensitivity and general fearfulness of canine behavior

Researchers in the Hannes Lohi research group in the University of Helsinki focused on two forms of canine fearfulness: noise sensitivity and general fearfulness.

Experimental drug can positively modify key characteristic behavior in FXS patients

Researchers at MIND Institute at UC Davis and Rush University Medical Center have found that mavoglurant, an experimental drug known as a mGluR5 negative modulator, can positively modify a key characteristic behavior in individuals with fragile X syndrome.

Scientists aim to find genetic causes of developmental abnormalities in the vagina and uterus

A percentage of females are born with a missing or underdeveloped vagina and uterus, and scientists are working to analyze the genes of hundreds of them to get a better idea about causes, improve genetic counseling and ideally treatment.

Unexpected connection found between feeding and memory centers of the brain

The search for a mechanism that could explain how the protein complex NCOR1/2 regulates memory has revealed an unexpected connection between the lateral hypothalamus and the hippocampus, the feeding and the memory centers of the brain, respectively.
