HuBlym-1遺伝子の配列変化が,バーキットリンパ腫におけるその変異活性に寄与するかどうかを調査する.
増加したHuBlym-1遺伝子の転写が,その腫瘍発生的可能性を説明するかどうかを判断する.

主な方法:

バーキットのリンパ腫細胞系からの再結合クローンのDNA配列解析.
バーキットのリンパ腫細胞系におけるHuBlym-1遺伝子転写レベルの分析.
細胞焦点形成アッセイは,NIH 3T3 細胞変異後のものです.

主要な成果:

バーキットリンパ腫のHuBlym-1クローンと報告されたシーケンスの間で,シーケンスの違いが見つかりませんでした.
バーキットのリンパ腫細胞系ではHuBlym-1遺伝子転写の有意な増加は観察されなかった.
HuBlym-1にクロスハイブリッド化した,しかし焦点を誘導しなかった再結合DNAクローンが配列化されました.

結論:

ブルキットリンパ腫におけるHuBlym-1遺伝子の変異活動は,配列変異によるものではない.

Histone Modification

The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone deacetylase,...

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Heterochromatin

The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at 9th...

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
