Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Gene
  • Enzyme

Hitoshi Okamura mainly investigates Circadian rhythm, Suprachiasmatic nucleus, Endocrinology, Internal medicine and Circadian clock. His research in Circadian rhythm intersects with topics in Epinephrine, Denervation and Cell biology. His research integrates issues of Genetics, Period, Cryptochrome and Mesoderm in his study of Cell biology.

His Suprachiasmatic nucleus study incorporates themes from Molecular biology, Vasoactive intestinal peptide, Norepinephrine and Period Circadian Proteins. The various areas that Hitoshi Okamura examines in his Endocrinology study include Regulator, Receptor and Rhythm. His Circadian clock research is multidisciplinary, relying on both Messenger RNA, Transcription, E-box and Ratón.

His most cited work include:

  • Control mechanism of the circadian clock for timing of cell division in vivo. (886 citations)
  • Light-Induced Resetting of a Mammalian Circadian Clock Is Associated with Rapid Induction of the mPer1 Transcript (754 citations)
  • Synchronization of cellular clocks in the suprachiasmatic nucleus. (751 citations)

What are the main themes of his work throughout his whole career to date?

His main research concerns Internal medicine, Endocrinology, Circadian rhythm, Suprachiasmatic nucleus and Cell biology. Internal medicine is closely attributed to Nucleus in his work. His Endocrinology research is multidisciplinary, incorporating perspectives in Neuropeptide and Vasoactive intestinal peptide.

His research on Circadian rhythm often connects related topics like Gene expression. His Suprachiasmatic nucleus study combines topics in areas such as Molecular biology and Messenger RNA, In situ hybridization. The concepts of his Cell biology study are interwoven with issues in Period and CLOCK Proteins.

He most often published in these fields:

  • Internal medicine (46.82%)
  • Endocrinology (45.58%)
  • Circadian rhythm (26.68%)

What were the highlights of his more recent work (between 2009-2021)?

  • Circadian rhythm (26.68%)
  • Cell biology (20.67%)
  • Internal medicine (46.82%)

In recent papers he was focusing on the following fields of study:

Circadian rhythm, Cell biology, Internal medicine, Endocrinology and Circadian clock are his primary areas of study. His studies examine the connections between Circadian rhythm and genetics, as well as such issues in Gene expression, with regards to Zinc finger. His work deals with themes such as Transcriptional regulation, Period and Gene isoform, which intersect with Cell biology.

Hitoshi Okamura regularly links together related areas like Regulator in his Internal medicine studies. He usually deals with Endocrinology and limits it to topics linked to Vasopressin receptor and Vasopressin. The Circadian clock study combines topics in areas such as Kinase and Metabolic pathway.

Between 2009 and 2021, his most popular works were:

  • RNA-Methylation-Dependent RNA Processing Controls the Speed of the Circadian Clock (498 citations)
  • Salt-sensitive hypertension in circadian clock-deficient Cry-null mice involves dysregulated adrenal Hsd3b6. (299 citations)
  • Mice Genetically Deficient in Vasopressin V1a and V1b Receptors Are Resistant to Jet Lag (217 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Gene
  • Enzyme

Hitoshi Okamura mainly investigates Endocrinology, Internal medicine, Circadian rhythm, Circadian clock and Cell biology. His Internal medicine research includes elements of Genetic translation and Neuroscience. He studies Suprachiasmatic nucleus which is a part of Circadian rhythm.

As part of one scientific family, Hitoshi Okamura deals mainly with the area of Suprachiasmatic nucleus, narrowing it down to issues related to the Receptor, and often CLOCK Proteins and Thermoregulation. Hitoshi Okamura interconnects Gene expression and Purine metabolism in the investigation of issues within Circadian clock. Hitoshi Okamura has included themes like Phenotype, Lineage and Period in his Cell biology study.
