Major Hormones and Their Functions01:27

Major Hormones and Their Functions

2.7K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Abnormal Proliferation

5.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Hormones of the Pituitary Gland01:27

Hormones of the Pituitary Gland

14.9K
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

5.0K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Tumor Progression02:07

Tumor Progression

7.8K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Area of Science:

  • Neuro-oncology
  • Endocrinology
  • Neurosurgery

Background:

  • Pituitary adenomas (PAs) constitute about one-third of intracranial tumors.
  • Non-functioning pituitary adenomas (NFPAs) are the most prevalent type of PA.
  • NFPAs present therapeutic difficulties due to their proximity to critical structures like the optic chiasm and pituitary gland.

Purpose of the Study:

  • To address the lack of effective medical treatments for NFPAs.
  • To investigate growth patterns and biological markers of NFPAs.
  • To identify potential targets for future medical therapies.

Main Methods:

  • Review of existing literature on pituitary adenoma classification and treatment.
  • Analysis of studies characterizing membrane receptors in NFPAs.
  • Exploration of potential biological markers for tumor aggressiveness.

Main Results:

  • Current therapeutic options for NFPAs are limited to surgery and radiation.
  • No reliable markers currently exist to predict NFPA aggressiveness.
  • Characterization of NFPA membrane receptors shows promising results for targeted therapies.

Conclusions:

  • Further research into NFPA growth patterns and biological markers is essential.
  • Understanding these markers could enable personalized patient care.
  • Promising findings in membrane receptor studies may pave the way for novel medical treatments for NFPAs.
