(SDH)-deficient renal carcinoma: a morphologically distinct entity: a clinicopathologic series of 36 tumors from 27 patients.
CBT are associated with mutation of Succinate Dehydrogenase
Complex (SDHx) gene17.
Taking into account the patient's age, family history, the size of the tumour and the presence of metastases, the specimen was referred to the Department of Pathology at Brigham and Women's Hospital, Harvard Medical School in Boston, Massachusetts, for immunohistochemistry for succinate dehydrogenase
subunit proteins, as this was not available in South Africa at the time.
The succinate dehydrogenase
enzyme is also known as Complex II in the mitochondrial electron transport chain, and consists of four subunits (A-D), with subunits B, C and D associated with PCC and PGL.
Stratakis, "Succinate dehydrogenase
(SDHx) mutations in pituitary tumors: could this be a new role for mitochondrial complex II and/or Krebs cycle defects?," Endocrine-Related Cancer, vol.
is a heterotetrameric complex composed of 4 subunits, SDHA, SDHB, SDHC, and SDHD, and 2 assembly factors, SDHAF1 and SDHAF2 (20).
activity: The activity of succinate dehydrogenase
in MII oocytes (n=10 in each group) was detected by the method described by of Vivarelli (48).
While their inhibitory effect on NADH dehydrogenase (complex I, NDH) received most attention [8, 23, 24], it was also reported that biguanides can inhibit other dehydrogenases in the mitochondrial respiratory chain, namely, succinate dehydrogenase
(SDH)  and mitochondrial glycerophosphate dehydrogenase (mGPDH) .
Estimation of Succinate Dehydrogenase

Histochemical stains showed normal myophosphorylase, phosphofructokinase and myoadenylate deaminase, succinate dehydrogenase

About 70% paragangliomas are sporadic, 30% are hereditary, having identifiable germline mutations of Succinate Dehydrogenase
